Wiring Problem on 2002 LT

I need your help. I just got the rear trunk repainted on my LT.... beautiful job by the way! The body shop disassembled the trunk (speakers, backrest, power point, brake light on upper rack, etc and gave it back to me reassembled.

I installed the trunk on the bike this afternoon and now the right rear speaker howls with a high pitch sound like feedback... (the bike does not have a BMW intercom connected to the speaker so there is no possiblity of microphone based feedback...). The rear brake light on the luggage rack does not work either. When the feedback is happening the radio does not play through the front or rear speakers. If I disconnect the electrical connector for the rear speakers, powerpoint, and luggage rack the howling stops.

I don't think that it is possible to incorrectly connect that main connector under the passenger seat. I have not started to disassemble the trunk yet to find the problem. I was hoping someone could give me some advice of where to look based on previous experience.

Thanks for your help.

Cool

Gibby, common sense and basic troubleshooting will tell you that the problem is something in the trunk. Unless you had the problem before removing it. The squeal in the speaker sounds like something may be either shorted, or connected backwards? I'm sure one of the senior gurus here will chime in with more precise suggestions, but do make sure you don't have any water in any of the connections since that will certainly give you problems.

Good Luck,

John

Is is possible you pinched some wiring when putting the trunk back on?

Thanks for your advice. It turns out one of the wire harnesses got pinched and worn through behind the backrest. I guess when the body shop reassembled the trunk, they shifted the wires around and the two bare, worn through wires touched!

All fixed now!
