Do you have a voltmeter, or do you have a buddy that can make electrical measurements?
Aha, yes. Mine is a Wineguard PS-1503.

I have a meter, and know basic electricity, but know nothing about how this system works. What/where should I check? Can this thing go haywire, correct itself overnight, be fine for a year or so, then go through the exact same cycle again?

If it's working fine, like it is now, should I expect a voltage reading to be off or would I have to wait til it goes out again?
