Has anyone done an internal regulated alternator swap on their trucks? What about the GM cs130?

 

Is there some reason you are wanting to do this? Regulators are dirt cheap and don't require an alternator swap at a hundred bucks plus when they go out.

 

I agree with Chad completely. FoMoCo uses external regulation as a safety valve.

FoMoCo externally regulated style Alternators go from $29.95 & up for a rebuilt and Regulators go for $8.95 and up with a good one going for around $15-$18. So a well rebuilt Alternator for 49.95 and a good regulator for $18 is what worse case $67.95? But the worst case with a FoMoCo system usually is just a regulator, or if you jump a lot of people or get jump started a lot, a diode array in your alternator. $18to $30.00, right?

A 1 wire Alternator is roughly $120. You'll have to create alternator to your system wiring with fuse link. Everytime it goes bad (they do go bad) it all goes bad which = a new alternator and in that scenario, it's another $100+ Repair Where is the advantage or logic to that change. . . . .

IF you use regulator as a sacrificial safety fuse, you're out the price of a regulator, $8.95 to $18.00. But when a 1 wire Alt goes out, you're out a $100-$120 Alternator.

Yup! I use a GM 12IS about 100 amps + or -. Wrote a technical article about it here. Easy swap costs less than a 100 bucks and solves a bunch of rotten wire and multiple connections issues. Ford stuff works well its just that I prefer a reliable easy to install charging system. I drive my truck every day. Read the tech article and post back with specific questions if you need help. IMHO!

 

Thanks WILLIAM.I did it on my 1968,1969,1972 chevy trucks and they work AWESOME!Now I want to do the same to my 1965 F250.GET RID OF ALL THOSE WIRES!!!Besides that more powerful electrical system=more efficient ignition system.

 

I shoulda known this was a trick question & you were going to change to a GM alt. all along since you have done it 3 times already. Why bother to ask, if it's your intention, to do it so we can waste our time?

That's what is AWESOME! (and a tad rude too)

THANX . . . . . . I'll remember it

Oh, BTW A more powerful charging system does not give you more powerful ignition. 12v = 12v no matter how many amperes are involved.

FordBoyPete, I think lance65 was asking the question because his other three conversions were already GM products. I agree with you on the ignition statement, 12v is 12v no matter how you look at it! Now a different coil I'd buy, but changing the alt will not effect the ignition system.

 

I swapped to a internal GM alt on my '63.
Got tired of replacing generator brushes.

 

I agree that 12v=12v.But when your charging system is operating effeciently then all other electrical systems will operate more efficiently.And B-T-W this was not a TRICK question just because I have "4" GM vehicles and "3" fords. AND I was not being RUDE!!

 

I did it and if you tell them the alt is for a tractor (can't remember which one) you get the same alt. but alot cheeper.
