I had a battery go bad on me a few months back. Since then, the radio has been intermittently losing power:
1) display goes blank for a fraction of a second, then comes back on displaying clock as 1:00
2) radio/cd quits playing if it was on
3) No apparent loss of power to anything else I can see at the time (instrument cluster, headlights, windows, etc.)
It seems to happen more often with cold, bumps, or when operating the windows, but I haven't figured out a way to make it happen on command.
Anybody seen this before? Do any of the following sound more or less likely than the others?
1) HW problem with radio or something else in the circuit
2) wiring or connection problem
3) Something else drawing a short gulp of power and starving the radio
My experience troubleshooting intermittend electrical problems is limited to guitars and amps. For those, I just turn it on and poke at stuff till I hear the problem show itself. In this case, I guess that means turning up the radio while I wiggle wiring harnesses.
