As usual, good advice Steve. There is a nicely done tech tip on how to convert your stock ammeter gauge to a voltmeter. When I get finished with the Warning Circuit and fine tune the Heater controller, I am going to sit down with a few gauges and do that tech tip. I know they did an amazing job with it. My concern is it is not for the weak. It's a pretty involved and very intricate process. If I can do it, anyone can, so I guess we will see!

I have an Engineer friend who pointed out to me that the original Ammeter is merely a D'Arsonval meter movement and there is no reason we can't just reconfigure the inputs. So I sent him a nice NOS Amp Gauge for our trucks. He looks at it and says, NEVERMIND I WAS WRONG, too much involved.
