Kevin & Ros Posted May 17, 2017 Report Share Posted May 17, 2017 Our motorhome is a 2014 THour Miramar. On our last trip, I noticed voltage drop whenever the motorhome was not connected to shore power or running off the generator, including when the rig was running. I have checked the circuit breakers and fuses. Any ideas? Link to comment Share on other sites More sharing options...

Kevin & Ros Posted May 17, 2017 Author Report Share Posted May 17, 2017 Thanks. Since the batteries were the original stock batteries, I thought weak batteries were a possibility. Link to comment Share on other sites More sharing options...

BTW, there should be no difference between shore power and generator power. Both provide 120V to the MH. Now when the rig is running, the engine alternator could be providing 12V power to the house batteries. Some Mfg wire their rigs to do that, others don't.
