Alternator in my 62 Grumman Olson kurbside is bad and I can't seem to find a replacement that looks correct on images. Does anyone here know what I need?

Can you put up a picture of what you have? Instructions for posting pictures are on the left of every page. It is very easy.

It's in a tight spot. Just my luck finally get a 60s vehicle and still can't find the room to work on it. Lol

That looks like a pretty standard Delco-Remy generator. There is a voltage regulator somewhere, at the end of the two wires attached to the terminals.

What can be seen of the insides looks pretty good, the brushes are not worn and the commutator looks good.

The wiring looks poor, I would start there. Take that blob of tape or whatever off the brown wire and see what is underneath. Repair the repair so it has good current capacity and clean up both of the connections at the terminals. It just might work then.

There may be an oval shaped data plate with the name "Delco-Remy" on it as well as numbers. From the rusted look of the area, the plate may be gone. It was held in place with a small rivet at each end of the oval.

That's not an alternator- - - -it's a 12 volt DC generator. There will also be a regulator mounted somewhere in the engine compartment, a rectangular box about 3 by 4 inches, about 3 inches tall, with 3 wires attached to it. You'll need to figure out whether the generator, the regulator, or the wiring (or any combination thereof) is the actual problem. I'd strongly suggest getting some professional help, since calling the item in your photo an "alternator" speaks volumes about your experience with older charging systems. The first thing I'd suggest would be to disconnect, clean, and reinstall all the wires, AFTER disconnecting both battery cables. Short circuits destroy wiring harnesses, and sometimes entire vehicles, in a big hurry!

Well that explains what that 3x4x3 box was that I found in the grove compartment. I'll pull out the ol multi meter and start hunting. Sadly much like the carb and master cylinder the serial plate appears to be gone. Thanks for pointing me in the right direction guys!

Check out this tech tip I wrote a few years ago. The title says "6 Volt" but the same principles and procedures will apply to the later model 12v systems.

So, the reason I thought it was bad, was I noticed my battery was charging.

So while it was idling, I disconnected one of the battery terminals and the engine died. So now after finding out its a generator system and 45 minutes of YouTube later... Is it correct that the generator doesn't charge the battery or provide enough power to run the engine at idle?

The furthest I've driven this since I got it was less than a quarter mile. So I've never had it up to speed to actually generate anyting.

Thanks Jerry I'll give it read in the am smile
