Re: internally regulated alternator: resistor or no resistor?

My 12SI alternator and my ammeter work perfectly, no idiot light and no resistor.

Re: internally regulated alternator: resistor or no resistor?

I sell volt gauge conversions for these trucks. If you run any thing over a 60 amp alternator, the amp gauge will not work correctly.

This will correct that and let you read actual battery voltage.

Contact me if interested.
