Looking for a digital ammeter for my tractor that reads negative as well as positive amps. The digital ones I've seen only register the amps in one direction. Any help?

That should do the trick! Thanks for posting.
Thinking about ways to provide the external power supply: Wonder how long a 9 VDC battery would last given the Power consumption: <= 20mA?
Perhaps a way of switching the 9VDC off when ignition switch is off. Or spend a few dollars and get a DC to DC isolater?

The 9 volt battery would be a pain.. Always dead when you need it.. I would keep looking for one that did not need an isolated power supply. Or you could do the isolated power supply thing I guess.
