Alex: the S3 car has only 5 pleats on the front seats. The S2 has many more,
narrower pleats. Your car is a S2. While the S3 was on sale in the 79 model
year in the UK, the North American sales began for the 80 model year. So,
back to fuse #9. On the S3 car this is reserved exclusively for the rear fog
lamps, which neither your car nor any North American S3 had. On the S2, fuse
9 is, as you say, for the RH side and tail lamps, and this car does not have
the “bulb out” warning lamps, does it? In any case, the panel in the trunk
is easily removed if it is like the S3 in trim: 2 slotted plastic screws and
it pulls off to reveal the ECU. I think we really need some help here from a
S2 owner.

Great, thanks, we do have the churchy tail lamps – I’ll check the seats
tomorrow.

S3 if

you have triangular rear tail lamps rather than “church window” shaped
ones.

Lots of other details as well, like wide pleats rather than the very
narrow,

multiple pleated seats of the S2. In any case, I will have to check my
schematic tomorrow (Saturday) and follow up on this.

Gregory, thanks. Ours is a SIII, because of the consensus on EFI,
etc., I

think. The ground on the right front sidelamp was just replaced
completely
with a new setup, involving soldered connections for both ground and
power

and

I know it works. There’s just no power on fuse #9 (LHD, left side
box),

which

indicates on the fuse map that it’s for “Right Side/Tail Lamps”. I’ll
check
the fuses in the back you mention – how do you get the panel off? Is
the

passenger-side fuse panel obvious to get at?

Thanks,

Alex

Alex: the S2 car is different in detail so what I will tell you may
not

apply exactly. On S3 cars the bulb failure unit for rear bulbs, AND
the

in-line fuses for the rear lights are behind the rear seat panel in
the

trunk. The front bulb failure unit is located on the passenger side
fuse

panel board, and here are also the fuses (3A) for the front park and
side

marker lights (#14 and 15, but these may be different in your car).
Since

the right and left rear marker lights are on the same fuse, for
example,

I

doubt that this is your problem. I would suspect faulty grounds. The
ground

for the right front marker and park light on the S3 is located on
the

inner

fender, right side. The rear ground point is on the inner fender
(behind

the

trunk side panel) in the trunk. Be aware also that the North
American

side

marker lights have a strange ground at the light itself. It is a
bullet

connector that fits into a circular sleeve. Very exposed to mud and
moisture, so a cleaning of this would not hurt. It is visible at the
rear of

the lamp, in the front fender. The rear light of course is protected
by

the

inner fender, so that is not a problem. I hope this helps.

Gregory, all right side markers and tail light are out and no
power is

on

fuse

9 – this comes from the burned-out lamp detector and the main
switch.

Where

is the detector? Could the main light switch have a bad contact?

Gregory, thanks, yes we have 10, 1" pleats on the seats, with wide side
sections. I have the cover over the ECU off and am messing around looking for
more fuses. I see no fuse block under or in the glove box.

I’m wondering if the main light switch has a bad contact – I’ve fiddled with
it, but looks like I need to remove it. There are 2 Philips screws coming up
under its exterior plastic shroud – I assume those will help.

At your service! I believe Alex and I have identical cars, so I may be
able to help. Unfortunately, I’m at work and the Jag’s at home. Also, I’m
not sure what the question is. Your right rear tail lamps are not working
and you are looking for in-line fuses in the trunk? Let me know what you
want me to look for.

have to be very careful when buying parts.

Dave, as I mentioned to Gregory separately, I took a motorcycle battery,
popped the top end of fuse #9 and connected it to the battery – the lamps all
worked (RH side/tail + license). So the fuse is not being fed power from the
switch. I don’t know if the car is supposed to have bulb-out detectors,
because of the confusion between SII and III you point out. I do know the ckt
diagrams show two terminals on the main light switch – one for fuse 8 (LH
side/tail + fuse 7 and panel-lamp dimmer), and one for fuse 9 (RH side/tail +
license). So it looks like I take the fuse panel & switch out to find the
trouble.

I found nothing but the ECU in the trunk and no fuse panel under the glove
box. Also, no puddle lights – have to get some like my 82 Accord has and put
them in! The Accord’s coil cover works well on the Jag, so why not?

By the way, I do hope our cars are close, mine is VIN: JAVLN49C111236. Since
I need the right rear outside chrome trim for the rear window (screen), I
guess I need to determine exactly what will fit.
