A 10 amp CB in series with a 4 watt testlamp.

Can you see that only 1/3 amp can be flowing in this series circuit.

I = P/V, so Amps = 4 watts /12 volts.

That is why this CB in series with a testlamp can't possibly trip.

Sorry I can't give any further input to your problem though Evan.

Gary,
I understand your point now. Not sure of the test lamp wattage, or even if it acts as a current limiting device (I'd think not, but then again I'm just a knuckle-dragging metallurgist that has tried for several months to find and fix this gremlin so what do I know?). Here is the video instruction I followed that prescribed wiring the test lamp in series with the CB. Seemed to work?
