alternator swap help?????

My og generator took a dump today and i want to buy an alternator. Anyone got any tips on which one to get and what kinda brackets i need. I havent looked inside to see yet.

The previous owner of mine ditched the generator for an alternator but it looks like the stock brackets were adjustable enough to fit what he put in it, as the brackets look stock. The one in mine is from a 67 GTO. I had to get a 67GTO voltage regulator as I couldn't get it to charge using the Econoline one because it didn't have enough tabs sticking out of it. But to replace both alt and voltage regulator cost me about $75. I wired it myself and it charges great and the dash light even turns on and off as it should. I say this because when it comes to eleteical I am just aweful. If I can do it you can do it. Goodluck!

I have seen that you can upgrade to a Chevy Internally regulated alt from a pickup, mount it with a spacer for the lower bolt, eliminate some wires... just off the top of my head, tossing the suggestion out there if you are curious. I was able to buy an alternator and voltage regulator in our Canadian Tire stores, so I'm sure Autozone or whatever would stock direct replacements.

Cool i think im gonna go for the gm one wire alt.

Respectfully speaking but the Chevy single wire has been the hot one that a lot of people have been using for quite a long time,, HOWEVER the new rage is the Ford 3G alternator. Its smaller than the Chevy 100 amp, and puts out 90 amps at 600 RPM,, from 130 full out to as much as 150 when worked. I have bought four of them, one chromed, one plain Jane (new),, and the two at the bone yrd for $15 bucks each. Its a single wire, so you can dump all the wiring back and forth to our regulator.

Last one was bad,, it was supposed to be his discussion of belts and what AMP loads a single or double or serp can handle,, I cant locate it on his site anymore,, and the last post was not it,,, here is on specifically about his alternators though

Lol I know what you mean, I was kind of bummed when I found out that my replacement alternator was from GM, but it already fit so nice with the brackets it had already I wasn't going to go through the hassle. The previous owner put a mopar electric fuel pump on the van and after a week of having it on the road it crapped out. That junkyard alternator seems like a great idea.

Forgot to mention, the most important part of using this alternator, in case someone hasn't noticed??????? its cranking out 90 amps at idle!!!! how many times in stop and go traffic have you had to put it in idle and or slip the clutch and sit on the gas to keep the r's up???? this one puts out just about as much as the GM at idle!!!! the GM will only crank the amps at full speed..... important for headlights, heaters, fans and stereos when your stuck in traffic watching the temp gauge hit self destruct,,,, LOL..

so how do u eliminate the voltage reg when using a 3g? what wires go where from the back of the new alt

So im going to use a 1g alt (regular style) i had laying around from a previous 302 build. Im not sure about the new volt reg wiring though. The old volt reg has a tab that says ARM? Theres a small box under the old reg that wires up to it what is this? BTW wiring is not my forte haha.

I second this question. The previous (hack) owner of my van "converted" to a one wire alternator, now my battery keeps dying. Also, where in the world is the fusible link coming off of the alternator located, or supposed to be located. I'm about ready to burn my van to the ground if I can't get my battery to charge

I still haven't resolved my charging issue, i was just gonna replace the whole damn wiring harness when i get a chance.

I am having the same problem. My battery charged over night and is almost full. My neighbor and I are going to try and tackle this issue tonight. I think adding the new alternator is causing my regulator to drain the battery. These old vehicle and their electrical problems are a nightmare.

good Luck on your new wire harness. Im going to give this ago on my own and if I cant fix it I will take it to a mechanic and unwillingly willingly fork out the cash.

THE FUSE-BALE IN ours is the pink wire from the switch up front and not at the solenoid,,
vic

Actually,, I believe I am wrong, it is a resistor wire to the coil, and no fuse able link at all,, sorry.

Curious, as the AMP load on the link you used. If its a main line, I would suspect it be pretty high amps. Is there a reason why you simply wouldn't just use a breaker, so at least to not be stranded on the road if it tripped?? I had a Dodge years ago that left me out in the sticks one time,,,
