Alternator Regulator Part Number

[pantheroc]

What is the Alternator Regulator Part Number, 2003 and where to order?

Perfomred all the typical checks, drop on neg side, pos side, voltage at batt, voltage at Alt. Volts going low when hot, no significant voltage drop between battery and alternator.

You want the 4G white one. There is only three colors and the other won’t work.
