Blas,
The red light does come on when the key is turned on but not started.

The jumper didn't make any difference in the needle movement.

The voltages are as follows:

1000 rpm 1200rpm 1400rpm
Alternator 12.65v 13.44v 15.75

Solenoid 12.23 13.09 15.25

Battery 12.29 13.22 15.48


It seems that If I increase the rpm above 1400rpm, the voltage doesn't stop climbing to over 16 volts. A bit high?

I did locate the ground on the drivers side front.
