In the process of swapping in a 460, truck still had parts for a generator in. Thought I had it figured out till I found the horn ran off the generator's voltage regulator.
The diagrams I've found show that spot to be for the "A" spot and was supposed to connect to the generator, not the horn.

I also had a second larger generator voltage regulator attached to the fender at one point. So someone's worked on it and rather than try to work through the rat's nest I figured I should just ask for help on what goes where.

Alternator had 2 yellow wires to it, one running back to the cab (?)



Stator post is hidden




Before changing anything

How do I wire this up?


It should be pretty straight forward, but I'm not sure what needs to connect to the starter solenoid before the voltage regulator. And I can't seem to find a clear diagram.

Alternator grounded to the frame too?


Thank you.

 

Is the gauge cluster wiring still stock?

 

Have you considered using a GM one wire alternator? Pretty simple with one of those.

 

This is how I wired my alternator and regulator-
The second picture looks like the way the PO wired in the horn. The 10 gauge wire I looped through the battery gauge on the instrument panel. If your converting to negative ground, just be sure you run the looped wire in the correct direction.

 

Gauges are still wired stock to the best of my knowledge. At one point the business that owned the truck did a little work to it here and there. I can't tell the difference between 60 year old wiring and 50 year old wiring, so... hopefully?



Haven't looked into a different alternator, at this point just trying to keep costs down and use what I have.



Thanks for the diagrams. It made me realize I was missing something (below)


Guess the horn wiring confused me because on my '67 that I just did the wiring on the horn has it's own wires connected to the steering column.


Alright, after studying this a bit after taking a break from it...


So, guess what a Horn relay looks like? Not a second voltage regulator. So those 3 wires need to go back.

Also seems I won't be using "I", but I am still slightly confused on the purpose of it. To a indicator light for the battery? (it used to always be on, so I have something a miss in there too) Also not sure on anything that needs to be looped to the gauges? '56 was thankfully a 12v system, first year I believe.

I think I have it though:

Revised edition, "A" running through the light switch in the cab. Should be a small yellow wire on a '56. Not sure if I need to keep the Stator line connected or not?











So, that look good?
I appreciate the help guys. Yesterday was just one of those days.

 

The "I" terminal bypasses the ballast resistor on points-type vehicles that use a ballast resistor in the ignition circuit.

 

Ah ok. Thanks

From what I've gathered with my 460 and it's DuraSpark I'll have to hook everything up and test it to see if I need a ballast resistor. Also need to research that out more. Don't see one in the pictures I have of the PO's installation, but doesn't mean it's not there.
