1964 - Single Wire Alternator Conversion

[crindima]

Hi All,

I have a '64 with an alternator and a voltage regulator. I would like to covert it to a single wire, internally regulated alternator. I found this beauty at Ecklers (please see link below) and I was curious if anyone has performed this and more importantly, how to re-wire to make it work.

Any and all help would be greatly appreciated.

Thank you in advance.

Be very careful when changing the alternator on a 1964.

Probably should continue this conversation on the "modified" forum.

My bad - sorry - didn't see the modified forum. How do I move the conversation over? Thanks

Done.

So on a 1964, Ford routed all the power from the alternator through the AMP gauge on the dash. Everything was fine when it was new, but a little corrosion build up in the wire connections, and some electrical resistance forms, and electrical resistance coupled with electric current = heat. Even a small amount of resistance can make enough heat to melt wires and worse. If you add a alternator that can make more amps, then it can make the problem worse.

One way to avoid this danger is to take the amp gauge out of the circuit. Take the wires attached to the B+ terminal on the alternator and wrap the connectors in an insulator, like heat shrink tube, or something safe like that. Tuck it somewhere safe and don't use it. Replace this with 4 Gauge heavy duty cable that can handle 100 amps. Connect this to the same post on the starter solenoid as the positive battery cable. Safety says you should include some kind of fusing provision just in case the alternator develops an internal short. I used two 10 AWG fusible links in parallel from the 4-gauge cable to the B+ terminal on the new alternator.

I'm not familiar with this particular alternator, but hook up the other wires as the instructions say. Also add some extra grounding.
