I've been there done that. Sadly, no one on the list could ever predict
where such a problem can be. I ended up spending about $6,000 tracking
down the problem, replacing nearly everything in the electrical system.
In the end, it came down to replacing wires one at a time and cleaning
connections everywhere (especially ground). Electrical problems are the
worst!!

Ouch, sorry to hear of your pain. But consider that the best step,
cleaning each connection, esp. the ground ones, is something an
owner can do her/himself [if it were legal; a question I'll skirt..]
investing only sweat equity....

One major reason for such nightmares may be the average A&P does
not have a lot of experience troubleshooting intermittent electrical
problems.
