Thanks for the advise. I've already decided to go the route of either
tackeling the rebuild myself (rectifier is about $29) or taking to
a rebuild shop (haven't checked out prices yet). Charlie Brown's
write up seems pretty straight forward.
Only question I have, to the list also, is my Lucas alternator is
differently than any listed in the TRF catelog. It has a large 1 on the
backing (the black placstic casing) and then a box shaped outline with
numbers 5 6 7 vertically alligned in the box and then ACR next to the
My interpretation of this would be the alternator can be used/is equal
the 15 ACR, the 16 ACR, and the 17 ACR. The rear wire connector has two
leads, one with three wires (smaller brown, brown/yellow, and another
yellow or white (didn't check that closely yet)) and the other with two
(large brown/yellow and the ground wire). Anyone familiar with this
for a Lucas alternator? Charlie, are you listening?
