Just a quick note as I try to organize a procedure for diagnosing why my strobe lights have started working only periodically.
I don't do a lot of night flying, although I always use strobes, and I first noted the problem when we picked up the plane in Hibbing at night a couple of weeks ago to fly it back to South St. Paul. But, because I fly mostly during the day in the summer and that was my first night flight since.... geez, I don't know when... it's possible this has been a problem for a while. Anyway, at startup the strobes wouldn't fire although after awhile they came alive.
Sometimes they work. Sometimes they don't.
So I figure the problem is one of these.
a) The VP-50 switch itself. I figure this is easily diagnosed by reassigning that circuit to another switch and see if it works.
b) A loose or broken wire or ground at the power supply (or maybe at the VP-50 but not likely considering how many there are all bundled together. It's like freakin' ree-bar.
c) A bad power supply
So here's the Vertical Power VP-50 (may it rest in peace) question for those of you familiar with its operation .
Since the VP-50 is supposed to warn of a fault in the circuit and the annunciator is not illuminating, what is it NOT?
