Yes, I have the dreaded "grounding through the parking brake cable" problem, that I don't want to turn into the "Disco Inferno" problem. (Sorry, couldn't help it.) But it only happens when the lights are on, everything's fine in the daytime. Careful study of the Rave revealed three ground locations nearby: E301/E302, under the driver seat, and E303 under the console. (The white connector in the upper middle of the photo, under what looks like a mounting screw.) This, obviously, seems the most likely culprit.
Are there any others I missed that I should be looking for? I'm going to pull up the console this afternoon to replace the parking brake lever.
Thanks all!
