Ok, shore power is good, battery is good.
just want to be sure we are talking about the 12v system (furnace, led lights, hydraulic system and gas water heater) works on shore power NOT when shore power is disconnected.
We are NOT talking about the 120vac system (residential fridge) which is powered by the battery via an INVERTER.
Ok, put the battery disconnect key back in and turn it ON. Make sure you are on shore power.
We are going to test your self resetting circuit breakers in the battery compartment.
They are the 50A red looking things. They look like buss bars but they are circuit breakers.
Put your multimeter black lead to chassis ground (the frame of the trailer or the negative terminal of the battery).
Pull the covers off the breakers. Set your multimeter for DC volts. Put the red positive meter lead to each post of the breaker one at a time. You should have 12vdc on each one since everything does work on shore power.
Safely disconnect shore power. Check each of the posts again. Again you should have 12vdc on each post.
If you donít....the one that is missing 12vdc is probably faulty.
