kaypsmith Report post Posted August 22, 2020 Sounds like a fuse/circuit breaker between house batteries may be blown or tripped. Or a relay may not working. Share this post Link to post Share on other sites

Start with your meeter and work from the battery's till you find where the power is interrupted. I had a bad connection/cable end. I found the bottom cable on a stack of 3 on the battery was broken and not making contact it was still held by the plastic and didn't seem to move so it wasn't till I took the outher 2 off I found it. You would be surprised how many things require 12 volt power to operate/work. When the engine is running you have power from the alternator. Let me know what you find.
