Alternator?

[hwcurtice]

Are these pretty common? For a m1009? What should I expect to pay for one?

Common, meaning will I be able to hit up the local parts store and get one off the shelf?

They are a isolated ground, not common. Napa has a part number for them but people have reported here that is was not an isolated ground. Best option is to have a shop re build it.

Another option:

Only the passenger side has to be an isolated ground. One for a 1975 Cadillac Fleetwood is the same alternator but not isolated ground. It can be used on the drivers side. Shop around for the best price. If you rebuild yours make sure the shop understands that they are isolated grounds!

So actually, I need to determine which one is bad.

Not necessarily. Rebuilding both wouldn't be a bad thing.

I've got a pair of rebuild kits on order because mine are a tad weak, the most they will put out while still keeping battery voltage above 12.8 is 30 amps. Under $40 per kit is a lot of saved cash.

The kits contain both bearings, the main rectifier bridge, the field diode trio, brush set and filter capacitor. It takes me longer to get the alternator out of the vehicle than to overhaul it.

Perfect time to learn how to rebuild an alternator

Don't be afraid, they are very simple inside. Follow the TM's and take a few pictures during disassembly, you'll be golden! Not to mention piece of mind knowing your GENs are new again. Also be sure to replace the GEN dash bulbs, clean the bulb sockets, and may as well desire the pigtails at the GEN. Sounds expensive and time consuming bit it's pretty quick and cheap. Good insurance policy!

Desire pigtails? Not since 4th grade.... I'm thinking replacing all the dash bulbs is a good thing, for a 30ish old rig.

I'm actually waiting to hear back on legalities on the rig. The guy selling doesn't have the title, the fool.

When I registered due to age, I did not need a title. Most states will not with the age, only a bill of sale. I actually (best policy in most situations) kept my mouth shut when first registering and played stupid...which is not difficult. I had an SR97 doc from the US Gov't that is required for proof of transfer of ownership. Usually a smile and a friendly greeting gets you a long way at the DMV. Tell them only what they need to know.

Of course you will want to ensure your new purchase is not stolen!

Who doesn't love pigtails??? You are crazy!

The ones on your rig are thirty years old and more than likely brittle or melted. Always a good practice to replace. I recommend some nice marine grade shrinkwrap butt connectors. Good for another thirty years

I don't understand the desire term. I'm sure it was an autocowreck thing. Just want to know what you meant.

I forgot about the SR97...

I don't understand the term 'desire' I'm pretty sure it's just an autocowreck of something else, but it's too early and I haven't had enough coffee...

Be sure to drink lots of coffee before doing any electrical diag
