I have a drain on my 12volt system. I have found articles on how to find it. All of them tell you to pull fuses until your multi-meter shows a drop in amps. My problem is I have 12v DC circuit breakers instead of fuses. They are small round pegs about the size of a pencil eraser. They pop out when blown and you just push in to turn back on. However, I can not figure out how to turn them off to open the circuit to test for amp drop. Thanks for your help.
How many are there?
Here is how to do it
Put your ammeter in line and note the drain.
now, one at a time PUSH those breakers, like you are trying to reset them....
As a safety feature (Some 1-D-10-T types try to "Lock them down" so they do not trip so as a safety feature) When pushed they open.
When the meter reading goes down.. That's the circuit. (there may be more than one)
