76 duster..14.7 at idle climbs 15.5 with rpm increase. new-charged battery. used alternator.
battery voltage is 12.6..checking the ballast resistor blue wire key on at run i have 11.8 and same back probing blue wire at regulator plug. if i unplug the regulator i get 12.4 at the ballast and at the regulator plug blue wire, almost full battery voltage. after plugging reg back in and going to alternator i have 12.3 at alternator blue and 1.9 at alternator green. i unwrapped the harness between alt and regulator plug and blue and green wires are ok,no melt and have continuity on green wire from reg plug to terminal end. is there a short? or bad regulator?
