Faulty Battery Disconnect Switch? - UPDATE
The last couple of weeks we have lost 12V to the rv. Our inverter works great (connected directly to the batteries) and the batteries charge just fine. All fuses check out with the volt meter.
This is an intermittent problem and I am wondering if it has something to do with the battery disconnect switch?
Thanks in advance.
Found the problem. I took all the cables off for a good cleaning and found the heavy duty that runs betweeen batteries had been tightened too much causing the cable ring for the post to splinter and break. I had a spare as they come two in a box. 12Vs are back and working.
