Dead alternator - Type 4 bay, cant find a new one.

[72Bus_in_OC]

Alternator just went out and Im having a hell of a time trying to find a new one. I know there are re-builds online but trying to go new here if possible.

My brother in law was telling me that there are conversion kits for Chevy alternators, has anyone here ever done that?

The only new alternator I was able to find was in Belgium and can be here in a couple of days, bad news its $320.

You can buy a remanufactured at your local FLAPS for about $70

your local electric motor rewind shop should be able to rebuild it for you too.

55 amp easy to find. Most likely Telford has looked over Gary's (Aeromech). That would be the one to get. That said, be sure the backing plate clears the stud and washer, and make your own gasket.

Good news everyone! I found a brand new one in Perris (Autozone) which is about 40 miles from me. Driving over to pick up now.

[SGKent]

do not install it until you understand the stud and washer problem that exists or you will burn some things up.

If it's new, it is likely a Bosch for a different application that will kind of fit. As mentioned make sure the two studs on the diode plate have been shortened and that the one washer is either a small diameter one or has been clipped. There may be gaps in the housing that need to be sealed off as well.

Don't forget when you install the new one that it must get power from the wire that comes from the dashboard light... this is to magnetize! Don't ask me! I thought it was already defective...

Thanks for the info all!

I'm now zeroing in on the Black (15) from the ignition ..

I thought the Blue was powered by the Red from the Alt... but now I see that there's a jumper from the Black to the Alt Light .. to the Blue.

So, assuming the Black is cold.. and the Alt Light is cold.. would that prevent the Alternator from energizing / building Amps ?

Odd to me that the Alt light is off when the key is ON, but the Alt light is on when the engine is running. more staring at diagram is in order.

[SGKent]

did you verify if S9 has voltage on at least one side of the fuse. Count from the left.
