OK ROY YES BATTERY LIGHT COMES ON AS SOON AS WE TURN ON KEY BUT NEVER GOES OFF I SEEN ON YR DIA WE HAVE DIFF WIRES IN DIFF LOCATIONS WE HAVE A WHITS WITH A BLK TRACER ON ONE WE HAVE 12.9 V AT BK/OR OK DID YOU NEED VOLTAGE REF ON THE OTHER TWO ROY AS WELL

Expert:  roy replied 9 months ago.

GOOD INFO OK OURS HAS NO POWER TO THE WHITE AND BLACK WIRE IT SHOULD HAVE 12 VOLT REF CORRECT ROY IS THIS WIRE A FUSE TO IT SIR

Expert:  roy replied 9 months ago.

ok, did not see a wt.bk wire on the diagram. I found one that did.

I will post that. if there is no power there, the alternator is bad. it is fed from internal. it is a jumper

Expert:  roy replied 9 months ago.

it feeds the stator.
