I have had my 1991 XJ6 for about 2 plus weeks now and I have learned a lot. Here is what I did. I read my manual from cover to cover 4 times. I now know where to look for things and what the symbols mean. I have also learned to trouble shoot electrical problems. Most are not tough unless you have a short to ground and then you have to find out where. It just takes time to get used to where everything is at,how it works. luckly my 1991 is almost perfect. I had 1 blow fuse and have one intermittent alarm on a bulb failure. That one may be hard to find. Always remember this. Start with the easiest thing and work from point A to point Z somewhere in there you will fix it.

Welcome rrman03!

It's nice to have another member from Tennessee! Reading the manual is a great way to begin your relationship with your car, and confounds all the snobs who don't think we know how to read in Tennessee.... :-)

To continue your education, I would highly recommend that you visit the "XJ40 'HOW TO' quick links" thread on the home page for this forum and download these files:

Haynes Manual
AJ6 4.0L Engine Management System Diagnostic Guide

And also spend some time reviewing all the wisdom in the XJ40 eBook at the Jag-Lovers forum:

Hey rrman03!


Welcome to the forum! I'm new here as well, although I've been lurking at the Jag-Lovers forum for a while. I found a post in the archives there about corrosion on the contacts in the rear tail light housings that caused a bulb to have inconsistent power. The next time the bulb fail alarm comes on check your tail lights and brake lights to see if you can tell which bulb it is. Maybe you could try cleaning the metal contact for that bulb.


Oh, and like Don said, there are a lot of great resources available for our cars - don't forget the archives here and at Jag-Lovers. You can search for any problem and usually find lots of previous posts about how other owners solved the problem.


Best,

Welcome to the forum,

To 93SB's point, and from my personal experience, the problem may be with the BFM's in the boot. AS 93SB suggested, next time it happens, get out right away and examine the behavior of the light assembly's in the rear, turn on your flasher as well and ensure all bulbs are working.

It may not be a bulb, but the BFM controlling the affected light assembly. Common issue is poor solder joints on the BFM boards, which are usually simple to identify. Poor solder joints are typical to intermittent failure signals on the VCM.

Another thing you can do is clean all ground points on the vehicle. Though it may have been garage kept, the metal will still oxidize over time and needs to be refreshed with a cleaning on the lugs and the body contact point. Cover when reassembled with dielectric grease to slow down the oxidation process. Don B did an excellent pictorial on Jag-lovers.com of the process on his '93, yours will be very close to his in regard to ground locations. Go to the link below and view his various albums:

The cleaning of the grounds should be considered an "maintenance" objective every few years at the least.

Good luck and Take care.

Welcome indeed. Allow me to compliment you on your exquisite choice of cars.

Cheers,
