Hello all, after having problems with the charging system in my 1966 F100 and noticing all the old and twisted and ruined wires I figured it was time to do some upgrades to the electrical portion of the truck. In terms of the charging system I was planning on taking out the voltage regulator and alternator and replacing them with a new single wire alternator with a built in regulator. How would I go about connecting this to the new fuse box in the EZ wiring harness? Any schematics or descriptions would be appreciated.

Side note: I don't have much experience with wiring something to this scale, so I saw the EZ wiring harness 21 Standard Wiring Harness and figured that would be my best bet. Does anyone have experience with these or do I even need something with that many fuses? Any suggestions or other harnesses that would be easier and more suited to the truck would also be appreciated. The truck does have an aftermarket gauge cluster, radio, back up lights, and an electronic Pertronix distributor.

 

You should be fine with that combination and this link seems to confirm it. You should be able to wire in a one-wire alternator into any 12 volt negative ground system.

This is a easy hook up deal. You will need an 18 gauge ignition hot (likley green) in the original harness. Out put to the battery is 8-10 gauge wire with a 80 amp fuse.Get a GM jumper wire plug from the alternator supplier or NAPA. One thing, if you use a 130 amp alt with a single sheave pulley it will squeal at startup and at RPM on the freeway. 40 AMP is plenty.

 

Thanks William. What am I doing with that green ignition wire?
