I have tested like you said, and got very funny readings.
OK, I ordered new 12 v /8A breakers from Great Lakes Shippers to replace mine. Did not get them last week FedEx lost my package. These breakers are funny for me to understand. So here is my questions:
1. There is no reset button any where for these breakers, all I have by the switch is a small red light, is it supposed to come on when the breaker trips? or is it supposed to be on when the breaker is ok?
2. With not button that clicks out when breaker trips, do you replace the breaker every time it goes out?
3. I am thinking very strongly about changing over to a fuse panel. So would 12v/8A breaker be replaced with how amp fuse,10amp?
This novice thanks you for you very much for your knowledge and advice.
