Posted November 14, 20186 yr Good morning guys, Recently my "check guages" light has been coming on and the dash DC Volt meter would spike all the way over to the high side. When I stop the vehicle to check the voltage with my VOM the error goes away. What do you guys think this probably might be?

November 14, 20186 yr Author Which green wire would this be? Where would I find this? Under the hood?
November 14, 20186 yr Owner There are only the green and blue wires on the back of the alternator. Green is a variable ground for the alternator field. Blue is +12V when the key is turned on.
