Serious electrical Problems
We put it back on the car (attached the 2 cords). Everything was fine for 15 minutes then all of a sudden the electrical gauge on the dash Completely dropped to 8v!!!
I've heard the gauge on the dash just shows how your alt is running. Is this true?
The heater was blowing very low and the whole dash was very dimmed.
Please help!! Where do we get started?
I have a voltmeter.
