Today I'm going to take a closer look. Makes sense the voltage would spike if there is a bad ground or fault somewhere. I bet you would bet me on the main cables.

I quit buying the yellow tops. My CJ ate those things up. I thought they would be best for the winch. I have had excellent luck (so far) with the blues with winches. I too have gone to NAPA batteries and parts in general for that matter. I will only go to AZ, O'R, etc. for oil and paper towels.

Re: Voltage Gauge read 19 volts - Digital Meter says 14.2

So after cleaning all the cables and connectors, testing everything I could think of, I finally took it into my local Auto Electric shop. Turned out to be the Alternator. I didn't test this because I had just replaced it 3 months prior. Figured I could rule it out. Nope. Brand new NAPA alternator faulted inside. $400 later all is good.

Well I would have lost that bet, since an internally shorted alternator is very highly uncommon, but not the first one I have heard about.
