I put a new set of Sears Platinum batteries in my 2013 Eagle Cap in July 2013. I have 280 watts of solar running through a MPPT controller. My rig was in Yakima WA for several months earlier thi...

Either buy or borrow a multi-meter that has a clamp on amp meter. This is the one I have: Sears Clamp Ampmeter
With nothing hooked to the battery (disconnect either the positive or negative lead), what is the battery voltage? Is it in the vicinity of 12 volts?
With your transfer switch disconnected, all 12v power should be off, reattach the battery and use the clamp ammeter to read the current flowing out of the battery. It should be zero.
With everything turned off inside (lights, fan, fridge, etc), turn on your transfer switch. You should have a light load (ammeter may say zero or one) but anything much over 1 amp means you have a short somewhere. If this happens, I'd suspect up front since work was done there. Use the clamp ammeter on your wiring harness to find where current is flowing.
Hope this helps. Others may elaborate or have better ideas.
