Wiring Help 6.1 w/ factory harness

OK,my way of running my ammeter killed two birds with one stone.

I ran a separate wire from the output post of the alt - to the input post of my factory Ammeter.

HOWEVER - If you do this - you will reduce the current draw through your ammeter and it may not register any increase in load.

I did it because I didn't want to accidentally fry my ammeter if the regulator crapped out. Remember - these alts put out 150/160 amps...easily enough to kill your ammeter if the alt goes into overcharge - so if you want to run your ammeter - I suggest you run a separate wire to it like I did from the alt.

The ammeter "output" wire goes to the starter relay, just as your main alternator wire does.

Otherwise just don't connect it - if you have a voltmeter you don't really need an ammeter.


Cant help with voltmeter wiring...never run one.
