1992 244...what color wire is going to the battery light in the dash
bulb.
Leave that circuit alone...just plug in your voltmeter on its own circuit...use cigar lighter wire..or whatever has positive voltage.
Then fix the light bulb socket.... The exciter circuit works well. You will not add reliability by re-inventing it.
You do not need a resistor, just a signal from the ignition switch run position to the exciter terminal on the alternator. This wire needs to be capable of suppling 2 - 6 amps depending on the alternator and battery state of charge.
So I need to create a solution..
I re-wired my exciter wire setup.
The stock cluster does not work properly and the alternator would not charge.
I now have a wire running from a switched fuse (forget which one, but I could look), through a diode to the exciter terminal.
Works great.
You could modify this very easily to run a bulb, or voltmeter and not have to worry about fixing the instrument cluster.
You do not need a resistor.
