| Fuse
& Relay Panel Diagrams |
|
The Bentley Service Manual has numerous errors in its list for relays and
fuses. Most of those errors have been corrected here! However, it's wise to
verify your relays using the relay part numbers listed below.
The fuse/relay panel is located
under the dash, driver's side, behind the kneebar.
1980-1982 fuse/relay panel part number:
171941821C
1983-1993 fuse/relay panel part number:
171941821D
NOTES:
-
Fuse amperage:
Green = 30;
Yellow = 20;
Blue = 15;
Red = 10.
-
The numbers in the relay diagrams are
position locations and have no relation to the numbers on the actual
relays.
-
1980-1982 Cabriolets use
ceramic fuses.
-
1980-1982 fuel pump relay: Originally
installed in position 7; due to a recall, the relay should have been moved
to position 1 with a wiring loom bridge to position 7.
-
If your car has factory-installed heated
seats, the relays for this option are under each front seat.
-
If your car has a factory-installed 2-stage
after-run cooling fan system ('88-'89), the relay for this fan is mounted to
the left front fender.
-
If your car has a factory-installed power
windows, there is a control unit beneath the dash on the passenger
side.
-
If your car has a factory-installed power
top, there is a covered thermo-fuse above the relay panel.
-
If your car has dealer-installed daytime running lights, there
may be a relay in or above the
top row of the main panel relays (not shown in the diagrams).

diagrams |
|
Wiring diagrams can be found in the Bentley Service Manual as well as the
Haynes Repair Manual.
NOTE: Those with 1986 Cabriolets should follow
both the 1986 and the 1987 Bentley main wiring diagrams; much, but not all,
of the wiring in a 1986 resembles the 1987 diagrams.
Click here for an explanation on how to read the wiring diagrams (56K
warning!).
|
|
Warm wires |
|
Warm-to-the-touch wires are not at all unusual in these cars, due, in part,
to the way they were wired at the factory.
However, wires that become so warm or hot that they melt their insulation
and/or smoke are cause for concern. An overly warm wire is indicative
of a circuit with high resistance. This high resistance can be caused
by various issues: bad ground connections, poor wire connections, faulty
switch, faulty relay, etc.
|
|
Connecting the
OBD I diagnostic/scan tool |
|
Under the shift boot, towards the front.
NOTE: Only Cabriolets equipped with Digifant I engines have the OBD I
diagnostic port; furthermore, an OBD II diagnostic tool
cannot be used to pull fault
codes from an OBD I system!
|
|
Voltage
drop & voltage readings |
|
Voltage drop
is a common malady on Cabriolets due to a poorly designed electrical system. Voltage
drop can be witnessed on the VDO volt gauge with the engine running: When
turning on the headlights, for instance, the volts will drop from 14 down to
12 (the drop is actually more severe when reading the voltage at the
battery, then at the headlight; this is because the volt gauge is not 100%
accurate); the volt gauge needle will also bounce in rhythm with the turn
indicators. If the charging system is in good working
order and all ground wires/connections are in good shape, this is nothing to
really worry about. However, to combat voltage drop (and to
increase headlight output), install headlight relays, clean all ground
contacts and replace ground cables.
Voltage readings:
|
|
Reverse lights do not work |
| If the fuse/relay and bulbs
are okay,
replace the reverse (back-up) light switch located on top of the transmission
(on automatics, the switch is connected to/near the shift lever).
To test the reverse light switch: Disconnect
the electrical plug, jump the black and black/blue wire terminals, turn the
ignition switch to the battery-on position. If the lights turn on, the
switch is faulty. |
|
Headlights |
| Headlamp Type |
Description |
|
9003/HB2 |
A 7" round Halogen, dual-filament sealed-beam headlamp with lens
optics that came stock on Cabriolets in North America. These
headlamps are usually marked with "DOT" on the lens. If your
Cabriolet has the dual-round set-up, these headlamps are the outer
lights and are both hi- and lo-beam. |
|
H3 |
A 5" headlamp and single-filament bulb assembly that looks like
a sealed-beam headlamp ("H3" can also refer to just the bulb).
Once the H3 headlamp assembly is installed, only the H3 bulb
requires replacement when burned out. A small variety of wattages,
up to 100W, for the H3 bulbs is available. If your Cabriolet
has the dual-round set-up, these headlamps are the inner lights and
are hi-beam only (they are not driving lights, nor are they fog
lights!). |
|
H4 |
A 7" headlamp and dual-filament bulb assembly that looks like a
sealed-beam headlamp ("H4" can also refer to just the bulb).
The H4 headlamps use the same socket pattern as the 9003/HB2
sealed-beam headlamps and, therefore, are
direct replacements to the stock sealed-beam lamps.
Once the H4 headlamp assembly is installed, only the H4 bulb
requires replacement when burned out. These headlamps are
usually marked "H4" on the lens. A small variety of wattages, up to
100W, for the H4 bulbs is available. |
|
E-code |
European-spec (ECE) headlamp.
Stock-type lamp has lens optics; other E-code lamps, listed below,
usually are without lens optics. Has a slightly different (and
better) beam pattern than a U.S.-spec (DOT) headlamp and are
identified by the "E" logo on the lens. E-codes are actually
not street-legal in the USA, but can be bought from suppliers
listing the lamps as for "off-road use only". These lamps
usually use the H4 and/or H3 bulb listed above. These lamps
come with a higher initial cost than sealed-beam lamps, and one
replacement bulb can cost as much as a pair of sealed-beam lamps.
However, replacing just the bulb is much more convenient, and these
lamps can be used with higher wattage bulbs than what sealed-beams
produce. |
|
HID |
HID stands for high-intensity discharge. Rather than a
glowing filament, this type of lamp produces light by an electric
spark arcing across a gap inside a Xenon gas-filled capsule.
This type of lamp produces a brighter, truer-white beam of light.
Very expensive type of headlamp that can also cause glare problems
for oncoming drivers. |
|
Angel-eye |
Type of headlamp that produces a halo-effect when illuminated.
Predominantly used as a cosmetic replacement. Available as
both outer (H4) and inner (H3) lamps. The H4 angel-eye
headlamps are also available with cross-hairs. |
| "City
light" |
"City light" is a European term for a 5-watt parking light found
on the front of European cars and is located inside the headlamp
housing, or inside the turn signal housing. The reason for
these lights: When parking on the street at night, the right or left
(depending on which side of the street the car is parked) "city
light" is to be illuminated. City lights are not required in
the USA, but they come in handy if you've eliminated your
Cabriolet's stock bumper lights or have swapped your Cabriolet's USA
bumpers to "Euro bumpers". |
|
Crystal-clear,
smoked,
cross-hair, yellow,
blue |
Aftermarket headlamps that have crystal-clear lenses (without
lens optics), smoked (tinted) lenses, yellow lenses, blue lenses,
and/or with black cross-hairs in the center. These lamps
usually use the H4 and/or H3 bulbs listed above and, aside from a
wattage upgrade from the stock sealed-beams, these headlamps are
mostly cosmetic replacements and are usually E-code. |
| Note 1: If you live in
a state that requires bi-/annual vehicle inspections (not to be
confused with emissions tests!), using headlamps not stamped
with "DOT" may result in a failed inspection.
Note 2:
If you are upgrading the headlights to higher-powered lamps, you should add relays to the headlight circuit (see below)
to get the most out of your new headlights and to prevent
overloading the electrical system (higher-powered headlamps = higher
current draw). |
|
|
City lights |
|
If
you are installing city lights on a North American Cabriolet, wire the
lights to the stock wiring based on how you want the lights to be used.
Stock wiring in the car:
Black = turn signal
Gray
= parking/running light
Brown = ground
If
you're installing Euro bumper lights that include city lights, you'll need
to splice the two ground wires together prior to wiring them to the car's
brown ground wires.
|
|
Headlight relays |
|
Whether you are upgrading your headlights or not, it is a very wise idea to
relay the headlights. The stock headlight wiring uses paltry 16 gauge
wires, uses the headlight switch as a power source, and contains lengthy
wire runs, all of which cause resistance and, ultimately, voltage drop at
the headlights thereby reducing each lamp's luminosity. Adding relays powers the headlights directly from the
battery/alternator, will reduce voltage drop in the electrical system, will extend
the life of the alternator and headlight switch, will increase the light output giving you whiter
& brighter light, and will reduce
the chances of the headlight switch overheating.
Click here for a DIY guide for
relaying your headlights. If you'd rather not do it yourself, a
complete relay wiring harness is available for approximately $90 at
Concept1 , or for $35 at
4Crawler.

Lo-beam, 10.86 volts at

Lo-beam, 13.36 volts at

|
A standard Halogen sealed-beam headlamp produces 100% of its light output
at 12.8 volts (or 13.2 volts in Europe). Using the "before" image above and voltage drop
figures found on the Web, each of those headlamps is producing less
than 53% of their possible light output at 10.86 volts.
Pathetic! |
After installing the headlight
relays, each Halogen sealed-beam headlamp in the "after" image above is producing 100%
of its light output at 13.36 volts. Woo-hoo! |
|

relays, etc. can be found at

Headlight
switches |
|
Two different headlight
switches were used in Cabriolets. If you're replacing the switch, use
the table below to ensure you're buying the correct one! For example,
AutohausAZ lists the 321-K switch for a 1990 Cabriolet, which is the wrong
one!

Installing
LEDs |
|
Want
to brighten up your lights, or change their color, or reduce the power
drain? Replace the original bulbs with LEDs. LEDs have come a
long way in the last several years. Rather than buying LEDs and the
appropriate resistors, you can now buy LEDs that include resistors for a
plug-and-play application in most instances. Download the
DIY Guide for a how-to. The

**
LED numbers are based on
www.superbrightleds.com part numbers; this is one of the best sources
for LEDs. Any number listed with "x__" indicates that you can choose
how many LEDs come in the bulb.
General rule of thumb when it comes to LEDs: Replace the incandescent bulbs
with LEDs of the same color as the lens. In other words, front
side-marker light will require an amber LED; rear tail lights will require
red LEDs; instrument cluster will require green LEDs if you plan to keep the
green hue.
LED FAQs:
Q: Can the dash LEDs be dimmed? A: Yes.
Q: Can LEDs be used in the turn signals? A: Rear: Yes, but
you'll need to wire in resistors due to the lights being wired into the
hazard light switch. Front: Not unless you have Euro bumpers or
headlights with "city lights". The North American bumpers use dual-filament
bulbs.
Q: Can LEDs be used for the tail lights and brake lights? A:
Yes. But you'll want to buy red LEDs; white LEDs will wash the color
out.
Q: Which ones are better, regular or super-brights? A: It's
up to you. Generally speaking, if you're using colors other than
white, you'll probably want super-brights; if you're using white, go with
regular. However, it all depends on how bright you want your lights to
be. For safety reasons, you don't want your tail lights to be as
bright or brighter than your brake lights.
Q: What do I need to do in order to change the interior color?
A: You'll need to buy your preferred color LEDs and remove the green
film for the clock and tach/speedometer. If you like the green hue but
just want the lights brighter, get green (yes, green not white) LEDs and
leave the green film in the cluster (or remove the film, your choice, but
get the green LEDs).
Q: Can I install LEDs into the switches so they match? A:
Yes. You'll need to add a resistor to each switch light, however.
Q: How can I be sure the LEDs work before reassembling everything?
A: With the LEDs installed, apply power to them using a 9V battery.
If they don't work, reverse their positions (polarity matters with LEDs). |

Disabling
day-time running lights |
|
Canadian Cabriolets built from 1990-1993 have hard-wired day-time running
lights (DRLs) from the factory, as Canadian law requires DRLs. If, for
whatever reason, you want/need to disable the factory DRL system, locate the
yellow 20-gauge wire on the back of the headlight switch (it should be
plugged into the TFL pin); either push/pull it out of the harness connector,
or cut it and cap/tape it off. You can also disconnect the same yellow
20-gauge wire from the A-21 pin on the back of the relay panel.

Rev limiters |
|
The CIS Cabriolets have a rev limiter built into the fuel pump relay. When
the rpm's reach 6500 or so (for a 1.8L; lower displacement engines will have
slightly lower limits - see below), the fuel pump relay shuts off the fuel pumps.
This is a safety feature; however, the relay can be replaced with part #321
906 059 F so that the cut-off point is increased to 7500-8000 rpm's. It is
highly unwise to bypass this feature by installing a horn relay in place of
the fuel pump relay or rewiring the fuel pump relay because when the key is
turned to the "battery-on" position, the pumps will run continuously, even
in the event of an accident which could be cause for a very dangerous, if
not fatal, situation. Digifant Cabriolets have a rev limiter built into the
ECU and cannot be altered.
Approximate rev limits:
1.6L: 6000
1.7L: 6200
1.8L: 6500
