CJ gauges use 5 volts, not 12.

Re: Water Temp operation by itself. How to configure
They are pretty picky. Your method would rely on alternator output with
no regulation and the gauges would go with the rpm or lights or...
Mine has a punky rivet connection on the board inside so I sometimes
only get 3 volts and my gauges act accordingly.

no regulation and the gauges would go with the rpm or lights or...
Mine has a punky rivet connection on the board inside so I sometimes
only get 3 volts and my gauges act accordingly.

Re: Water Temp operation by itself. How to configure
I thought there was a rectifier in the alternator to keep it from going way
overvoltage.
The battery acts as a filter to get rid of a lot of that AC stuff.
But I agree....a separate regulator is what I'd use....
