If you happen upon some old fashioned analog ammeters, they're great, I have 100ma,500 ma, 1 amp, 3 amp DC meters, and a couple of AC versions which I haven't used in years. Put appropriate range meter at head of the voltage divider circuit and you can find out in seconds whether you have a problem, in which case, shut down immediately.
