So, i've been doing research, reading every post that I could, trying different things, but the solution to my electrical problem is a mystery to me. Here's the situation with my 87 325is:
Last Fall, I replaced the grommet seal on my trunk antenna; removed the antenna unit, unhooked the power to thread the grommet on. When I reinstalled everything, I noticed that my radio and OBC no longer worked. The OBC is backlit, and the radio only displays the time (the wrong time - always resets to 1:00). Other items that don't work: the tach, trunk light, the antenna.
When I start my car, the clock on the radio reads 1:00 with the OBC only backlit. The clock starts keeping time but once I press the power button on the radio, the numbers reset to 1:00, and the antenna starts to go up an inch before it just retracts and stops. The radio head unit doesn't seem to be getting power as trying to tune to a station, and the rewind/fast forward on the tape deck doesn't produce any kind of results.
What I've tried: replaced all the fuses in the engine compartment fuse box, tested continuity with a multi-meter on the fuses, checked the inline fuses behind the head unit (fine), checked connection on the back of the OBC.
So, I'm at a bit of a loss as to what to try next. SI board batteries, SI board solder? Is there an internal fuse in the OBC? Any suggestions on what I should try next? Thanks in advance for any help.
