Thank you Qmulus ,Miles and others who Pm'd me. In the middle of the night I realized what the cause was and wrote myself a note in case I forgot . Yes, I know !
In Post 1 "...(alternator) Terminal B1. So this is where the problem must be ??"
Correct but why?
Qmulus must have been dreaming about this also because he also got the right answer. There are 3 conductors that connect on the back of the alternator : 1 blue that goes to the instrument cluster(IIRC) -it has it's own connector.
The other large terminal with the 14(??) mm nut has the starter wire and one red conductor. This red conductor with a ring terminal was not connected.Exactly what Qmulus predicted. Thank you ! I can still see the i.d. tag "ALT"I made for it dangling.
Qmulus made another good point about carbon contamination of the bearings and the need to clean out the carbon from the motor to prevent the fan discs sucking it into the front bearing of the SAI pump motor.
But how to free the stakes on the face plate of the motor.?? I used a Dremel with a grinding wheel but it was a tedious process and lots of abrasive debris.Maybe Qmulus has a better way to dismantle the motor?
Thank you ALL who helped me !
