F100 How to One Wire Alternator With American Autowire Harness 

The alternator that Jeff is showing you is a Ford 1G style face plate grafted to a very common GM 10si one wire alternator. Anyone can do this dirt cheap via the bone yard. Notice the black plastic cap that covers the two male prongs for the idiot lite on GM applications.

Summit racing sells the wire with boot. They offer two different sizes for the fitting size along with several different lengths.

Will be doing the wire harness and alternator in my 67 soon.

Thanks for the update Jeff !

Your crimping in the previous video is adequate, especially soldering it after the fact. A home hobbyist isn't going to spend the money on that tool to only use it once.

I know this is an old video but very helpful. About to install a one wire on my mustang

time tag update didn't show up for me, so in case others don't see the same and want to know - it's @ 3:47

Everything I do must be supported by "on the road" parts availably. Say if a place like NAPA doesnt carry it Im out. Why? I drive everything I build, X country, on a given day. My 62 Falcon sedan delivery has made 3 trips to Ca and back, easy. Other trips include, SC, NY, FL, TX, CO, IN and OH where I live. I keep the parts package tabs in my folder thats with the car so I have the exact replacement. There was only one issue on the road...14 inch car tires, theres trouble.

What do you do about the alternator volt warning light with this particular system

Instead of the rubber boot insulator you could use shrink wrap

I have a 1972 Ford f100, and i want to install a one wire alternator just like you did. I was wondering how you wired the rest of the truck to that alternator?

One question... what about the brown wire labeled “ ignition alternator “ ???? I seen a wiring detail for a GM “SI” alternator ( where one side wires to the 2 wire plug in, the other ( heavier gauge) wire to the post going to the solenoid???or does this wire ( brown) need to be landed elsewhere ??? I bought a American Autowire kit for a 73 to 79 ford truck, and installed it ...this has been my biggest question

Know this is a old clip BUT, just bought a 78 F150 with 351M That I want to do this on THANKS

SEND HELP! If I go to a one wire, can I bypass my factory Voltage regulator? And if so, do I wire the power lead to the ignition switch (black with yellow wire) to positive stud on starter relay?

Ok thank u

I want to swap to a 100amp one wire, but the one that I got doesn't fit between the brackets and the heads. Where can I get a bracket that mounts in the low position like you have?

So, you need a boot for that one-wire terminal, Jeff?

Could you drop all your F100 vids in a play list?

What amp fuse able link? I’m doing the same exact swap as we speak

I have an 81 F-100. There's a wiring harness leading to the lights which has a plug that plugs into the alternator harness which plugs into the voltage regulator. Doesn't that harness draw power that way?

how do you run the horn wire that came from the regulator? Will it effect lights power ? asking cause ive got those issue

How do you get the bottom bolt out of the old alt? Mine is stuck. F-100 390

How dose it get ajusted

Solder that connection

Ok

Can i get away with a 20 amp automotiv circuit breaker

Really

So you don't need the excite wire on a one wire alt?
