I bought my 2015 R31CB last year. I have been having issue with the wipers, the mast light, the VHF radio and maybe some other issues. I finally spent a few hours on the mast head light and have nailed down a bad ground. My digital meter is deceptive because it reads 12 volts but as soon as you load the circuit the voltage goes to zero. My wipers start to move and then stall. My VHF radio turns on by itself and won't go on when I want it to. I think it may have taken out my stereo last year. Does anyone have any idea where to start looking? I had all six batteries replaced last spring when I bought it so it's possible the yard did not reconnect everything correctly. Any help is appreciated.
