alt conversion,,,

[caspear78]

is there any venders on the board that seel the one wire coneversion kits for an interal reglator for our trucks,,, and how much do they run?

Personally I wouldn't go with a one wire deal. They don't charge onless you rev the engine and if you get a screwwy pully ration you can have to rev it pretty high. That could kill the bettery if the wife or anyone else driving the vehicle don't get it to that magic RPM.
Plus replacements can have your rig parked for a week or so.


I would just go get an alt for a 77 c-10 with A/C. That'll get you a hefty alt with plenty of power. Then all you have to do is splice in the correct pigtail, and then at the regulator you just jump a couple wires and all is good.
There is also a plug in kit for the swap...but I couldn't tell you where to get it at.

I don't see what the big deal is about one wire alts.

Yeah there overrated i put one on a 73 bb 4wd blazer my cousin once had it was junky no voltage at idle.

I always put on the internal regulator alternators , its pretty easy to hook up just take the large wire off the harness that plugs into the alt and run it on the back of the alt on the charge post and run the other wire to IGN power but dont hook it to the same wire as the coil truck wont turn off like that..

and if you want an alternator larger than 60 amps dont ask for one for a 77c10 ask for one for a big caprice with elec windows or a 84 t/a ho Or a Z 28 there 95 amps

I think it was frank who sold the kit,very simple works great. Been awhile since I bought it and been buying alot of parts lately trying to finish it up. Sorry

I used an altenator off of either a 95 or a 98 silverado. I can take some pics of the wiring for you if you want. I find pics help more then explanations.
