It is a Ford alternator. No I have not put a shunt across it. I read it needs to be a 18 gauge across the 2 main large 2 terminals.

The have some very good information about alternator wiring and the pros and cons of one wire vs conventional. If the alternator has an internal regulator, it may not have the wire that needs to hook up to the gen light. There are 100 amp internal regulated alternators that are AC Delco brand that Hall Pantera was selling. I have one and my gen light did not work after I installed it, but there was a post on that back that would have allowed it to work if I had hooked it up correctly. I now have a single wire aftermarket 140 amp unit and there is no way to make the gen light work with that unit.
The problem with the Pantera amp gauge is that all of the power from the alternator is running through it. If the amp gauge fails, you are not going to be able to charge the battery.
