Do battery cutoffs and auto-reset breakers ...

...fail in such a way that they reduce battery capacity?

I put a brand new battery in my rig but this morning 20 minutes of furnace dropped the voltage enough that the main circuit breaker tripped then reset a few seconds later.

The only things between the battery and the 12V distribution panel and the cutoff and breaker (and the converter). They obviously "work" but something is dragging down the voltage. I've checked for loose connections at the battery but not at the converter or panel. I guess that's next.

    Ok first how much battery did you put in?

    The main breaker Tripped and reset? Is it a self resetting thermal type and how big. That should not happen unless it needs replacement.

    Please give us a lot more info

    Battery type and size (IE: Group 24, Pair of GC-2, multiple Group 29s, MARINE/deep cycle

    Breaker type and size.

    Did you prep this new battery by putting it on a charger before installing it? WHAT circuit breaker? If 120 vac then it would seem your converter was running full tilt trying to charge a depleted battery while also trying to supply sufficient power to run the furnace. You need to be more specific. ;)
  • Please clarify if you are on shore power or not. Are the "breakers" 120v or DC?
