I have a '92 740T Wagon which has some fault lights illuminated on the dash. The ABS light, the Bulb Out light, and the OD Off light all come on intermittently. Usually, if the ABS light and/or the Bulb light are ON, the OD light is OFF, and visa-versa. The other day, I found that the ABS light was ON, but dim. When I depressed the brake pedal enough to release the shift lock (you can hear it), the ABS light goes OFF, and the OD light comes ON. I was able to repeat this over and over while sitting in the driveway.

I'm assuming that this is a bad connection/ground somewhere, but if someone has seen something like this before or has any ideas of how I can narrow my search, I'd really appreciate it. Thanks.

Kevin.
