Libby007 Unless your a purist a 1-wire alternator is a good way to go splice bat. and arm. wires at the regulator change bulbs if not done already,gas gauge resistor,heater motor resistors (takes2 )use your fused heater switch. Only trouble may be alternator kinda hard to prime because of low R.P.M. Use as small an alternator pulley as is practical, ammeter should show charge work good. Bartimos is right get it so you can drive it not work on it all the time !!! oop change coils !!
