Alternator Dead? kinda long post 200

Charge the battery.... while you do that and it needs it anyway, haul out the alt again. Open it and find the diodes.... With no wires attached to the alt from the car set the ohm meter to XK, then prob a diode first one way then reverse the test leads... If it is a good diode it will read one way and not the other.... Do all of them....

If you find they are all good and read one way and not the other, then ask once again as test the armature gets detailed.

So far I am not convinced you have a dead Alt.....

DID you clean the copper slip rings, which the brushes run on?

With the engine off take a DC volt reading on the wires behind the ALT and again with the engine running.

I believe one is a ground so hold the volt meter probe to that, and with the red lead probe the other 2 wires... 1 should read the same as the battery even with the car off. The other one should not read with the dcar off, and 1/2 battery voltage with the car running...

What they do read is a mystery to me from here..

I am new here, and I like the way DF deals with giving the info, but I saw a need to try to add a bit more.. I hope this offends no one in any way. Mac
