battery disconnect

[lutodive]

Have GEOPRO 19FD 2019. I do not have any 12v power. When connected to my vehicle all lights etc work. My batteries are good. I tested them with a voltmeter. I tested the fuses and breakers. The other day I disconnected the batteries using the key. Reconnected I don't have 12v power. How do I test the battery disconnect to find out if is the issue or if I have another problem.
thank you

Can you test with your voltmeter at the disconnect switch?

Also, following the battery positive cable, there is a resettable circuit breaker. It will be on the A-frame of the trailer, or just underneath the front edge. You will have to lie on your back on the ground to see it (illustration below).

To test it:
Measure from each of the terminals to frame ground
12 Vdc on both-->Breaker is okay
12 Vdc on terminal closest to battery; 0v on terminal furthest from battery-->Breaker has tripped.

OR
Measure between the two terminals
Almost 0Vdc-->Breaker is okay
Around 12Vdc-->Breaker has tripped

If the breaker has tripped, press the tiny button on the end, just above the mounting screw, until it clicks.
