Re: Alt Field Circuit Breaker Popping

With breaker removed, Measure the resistance across the two terminals. Breaker in= 0 ohms. Breaker pulled= infinite ohms.
Ideally you would rig a rest with a DC power source, breaker, and load resistor. Dial up 50 amps. The breaker should hold. Dial up higher, perhaps 60 or 70 amps, the breaker should trip within a minute.
Or test without disconnecting the breaker. Engine not running, Turn bus on, breaker button pushed IN. Read battery voltage on both terminals. Button pulled, battery voltage only one terminal, 0 volts on the other

Update: I’ve located a 50amp breaker labeled MAIN. I turned on Master, electronics come on, and then I pulled the 50amp breaker. Nothing turned off. I’ve removed the breaker and would like to know how to test to confirm if it’s working or not.
Should all electronics turn off if I pulled the MAIN breaker?
