Front Alternator 8V92

[gregory O]

alternators require many working parts any one part that fails will not allow it
to work. when a bearing goes out it still pumps amps but the heat can screw the
windings and vr. if the prior rebuild didnt repair the bearing or other cause
for resulting failure replacing a burnt electrical component will be short
lived, like in your case. The other possibility is something is burning out the
electronics and replacing the alt will only prove that point with a third
failure.

Check the output when output wire is disconnected from bus batteries. I would
then take the alt to a good rebuilder.

one other test is to remove both ends of the charge wire, insulate the battery
end, then check for continuity with ground at the alt end. there should be no
continuity, if there is, 'continuous path' will show a ground fault which will
always demand amps.


You can usually find a referral of a local parts re builder from a local
salvage yard. WHen ever I am forced to buy a Pepboys reman alt or starter I drop
it off at my favorite rebuilder in Riverside Ca. they ship
