New to site, new to Mopar overheating issues
On the back of the alternator there should be one brush in an insulated holder. Green field wire attaches to the terminal on it.
If there is a second insulated brush with a terminal on it, that needs to be connected to ground.
On pre-1970 alternators, that second brush is in a non insulated holder and attached to the alternator casing. Those are don't require a grounding wire since the esecond brush is grounded to the case.
