I'm another one who hates electrics. If it were me I'd look at earth connections as already suggested, pull all connectors and get the contact cleaner in there. Sometimes just breaking then reseating connectors will get rid of such problems on it's own, but might as well clean em up while you're there. Electrical problems can be weird...(used to work avionics on Puma helicopters - bad earths were a common cause of all kinds of weird and not-so-wonderful behaviour. Pulling and reseating black boxes also seemed to fix more faults than I care to remember).
