2019 Thor ACE 30.2
My radio continues to inconsistently lose power, after replacing the stock Axxera with a new Pioneer. Some have said it’s a radio problem, but there’s no way different units from different manufacturers behave the same way. I replaced the new wire harness just to be sure that was good. Same issue.
Because I can run the radio while the engine is off, I know the radio runs off house batteries (this is normal). So today I thought I would connect the radio to the engine battery. First step, disconnect the engine battery. After that, the headlights still work and I can turn the engine over!
Also, earlier this year I installed a voltmeter directly to the engine battery and house batteries (separately) and it still shows power on both have power. So this means somewhere in the wiring Thor bridged the house and engine. Somewhere. What in the world?! And I living in a cuckoo clock?!
