The bulb failure warning light that has been intermittently coming-on is now glowing full time. As none of my bulbs are out I suspect this could mean a loose ground wire somewhere. Does anybody have any experience in tracking down this type of problem. Also, how can I find out where the grounds are located?

Thanks in advance for your comments.

Bill, hope this is of some help. I had a similar problem on my 945. I found that just replacing my rear brake and signal lamps with new ones did the trick. To check grounds, they should be very near the lamp housing. You may have to pull back some trunk lining to see it well.
