Default alternator - any special issues

I think that the alternator in my 1981 C3 died last night, and I plan to have the car towed to a shop today for examination. Are there any special issues with regard to this alternator of which I should be aware?

Don't have it towed just for the alternator. The alternator is an easy job (2 bolts) and I'll come over to help if you want me to.

Wow, thanks for the fast response. It's nice to see that there is another McKinney resident on the board.

As you can tell, I am as mechanically inept as there is. I therefore appreciate the offer. If I go to one of the local parts stores, are they likely to have the alternator that I need?

If you really don't mind helping me with this task, shoot me a PM or e-mail me. Thanks!

They should have one or be able to get one pretty quickly. It is nothing special or rare. Easy job should be able to switch it out in about 1/2 hour.

I'd do the same if I was still working in the area, But I think Bill is a whole lot closer.

Good luck, let us all know how it goes.

There is a local shop in the Pittsburgh area that you can walk, drive, or scooter your alternator to. With a set of multiple connectors he can hook up any brand of alternator to his testor and tell you what is/is not going on there. You should be able to find one in your yellow pages.

I 'upgradded' my alternator on my 1980. I got one from a 1986 Corvette. It puts out about 100 amp instead of the stock 63 amp. This is good if you have extra radio equipment or electric radiator fans. All I had to do was pull the pulley from the original alt and put it on the new 1986 alt.

There are 2 bolts that hold the alternator in. Then you have 1 bolt on the back for the ground wires, 1 nut that holds the positive wires and 1 two wire connector on the top. Make sure to disconnect the ground from the battery before you start anywork. Get a Haynes manual and they should have the removal / install instructions in there.

Guys that just drop in to run their count up and say nothing tick me off too

That said I picked up a truck 150 amp alternator and had no trouble bolting it in. I made the mistake of going for the single wire and it doesn't work that well. If you draw power from under the dash the single wire alternators can't compensate for the added draw and increase their output. They sense output from the alternator itself and any draw further down the road doesn't alow the alternator to increase it's output.

That's not fair. He contributes far more than

He weighs in frequently with and

Now if those three don't advance anyone's understanding of a complex techical issue, then I don't know what does.

An added thought.... If the alternator is bad then there is a good chance that the battery is dead as well. Bring a charger or some other means to jump it. Good luck.

Default Old Trick from an old man

A quick and cheap check for an alternator is to take a long steel screwdriver and hold it loosly near the alternaor while the engine is running. If the screwdriver is attracted magnetically to the alternator then you probably have another problem like the battery.

Post *****. Probably has low self-esteem. Needs to have big post numbers to feel good. Probably does not own a 'vette. Needs to post 35 times a day to feel worthwhile. Mech. ocupation is probably bogus, as he doesn't post mechanical help.

Why doesn't a moderator or someone warn these guys, that if they keep posting BS and those smilies in a tech or general forum instead of the OT forum, they will be booted out. Takes up Forum bandwidth, and I hate seeing all those smilies as the only thing in a message.

texaswilkins was of great assistance to me, and my '81 now has a new alternator and is up and running once again . . . just in time to get it indoors before the bad weather hits. Thanks to Bill and the board in general for the help. It was greatly appreciated.

This board has been real good to me and if I can return the favor by helping somebody out then that's the least I can do.
