I've got an ongoing intermittent electrical power loss on my 99 C70, where it dies stone cold dead - no dash lights, no power to anything at all. This usually happens at low speeds when braking, and is sometimes preceded by the stereo power dropping in and out.
After just a minute, it starts up again, no problem, just requiring the radio unlock code. No check engine lights, codes, or anything. It almost acts like a relay/circuit breaker is dropping out, then recovering.
I'm looking for a complete, detailed wiring diagram for it, figuring there are only a few points where it could lose power that completely. If anyone can point me to one, I'd appreciate it.
Likewise, if anyone has suggestions, I'm open to them. I discussed this in a previous thread - https://www.matthewsvolvosite.com/forums ... 5&p=132777 - that didn't gain me much ground, despite some good suggestions.
