Hi All

2002 r53 w/o xenon headlamps

Recently, accessories like ac, emergency flashers, directionals, headlight turn themselves off.
I've checked all the fuses.
Engine still runs.
Pull over turn everything off, wait 15sec or so. Start back up and all seems to be ok.

Is there a relay or a place to start diagnosing. I have 40 years of electronic troubleshooting, intermittent are always the worst.

I had a similar situation a while back. You can read about it here.

I had killed the battery and did not get it fully charged. Computer didn’t like the lower voltage I guess. Fully charged the battery and haven’t had any issues like it again.

There a few other weird electrical problems that steem from the front drains in the sunroof separating from the down tube. Water ends up in the passenger floor and eventually the one of the ECUs in the passenger footwell.

Couple places to start.
