Due
to some intermittent gauge operation and what seems to be the usual maintenance
for an XJ-S of this vintage, I decided to clean up the contacts on my instrument
cluster. Since I already had it out of the car, this is what I started with.
In order to properly prop up the cluster for a front view, I used a half-eaten
bag of Cooler Ranch Doritos. |
 |
| The
next step is the fun part. Take out all the screws. They are pozi-drive.
I found a set of drivers from size 0 -3 in a kit at Advance Auto. Snap out
all the bulb holders. Initially, I tend to group the screws by funtion in
order to remeber where they came from. Handle the flexible circuit carefully
and be sure to remove all the screws(1) that hold the black front facia
onto the white instrument pod. Additionally, there are two white plastic
retainers(2) for the flexible circuit that most be removed by separating
the black and white halves of the cluster and compressing the retaining
tabs from the other side. |
 |
| After
you get the screws out, you can carefully separate everything to get all
these parts. Handle the gauges with care to avoud bending/damaging the indicator
needles. I found an inherent defect from the factory in my tach. The sub-structure
had been twisted, probably as a practical "rework" to make it
fit. When I tightened one of the screws and re-installed, the tach needle
hung up around 3200 RPM due to interference with the screw. I added an extra
washer to regain clearance and all is well. |
 |
| The
clarity of this picture should explain all (I say this quite a bit, keep
in mind that it is, in fact, not). This is the flexible circuit and barrel
gauges laid out. All of the contact surfaces have been cleaned with my handy
sanding pen. Handle all of these parts
carefully as they are fragile. |
 |
| Reinstalling
the barrel gauges. Note that each one has two metal retaining clips(1) that
must be carefully replaced. Slip with the wrong tool on these and you could
be missing a needle on one of our gauges. I used a small, flat-bladed screwdriver
to push them back down into place. |
