24 volt generator

Anybody have pics of what wires go where on the generator/alt. wire 468 is obvious but which post under the cover does #5 and ground go to?

The stock alt has 3 wires total...

Under the cover:

1 large wire, #5, which is hooked to a stud under the cover with a nut, emerges from the alternator and runs to the foot starter switch and attaches to the same post the positive wire from the battery connects to.

1 small wire, 468 or 568, emerges and runs just past the cover and ends in a waterproof connector...the other side of the waterproof connector runs into the cab to a splice that slpits the wire into 2 outputs. One of these is wire #27 and plugs into the on/off switch and the other wire, also numbered as #27, feeds the spider harness which is the power to the gauges.


The ground wire hooks from the upper mount arm of the alternator, the one with the adjuster slide, on a bolt and nut, and connects to the alternator case with a bolt...near the cover on mine though there are a couple versions and this may vary slightly.

Are you saying your has 2 posts under the cover for the larger wires? Who is the manufacturer of yours? Leece Neville, Prestolite, Ford, other?

Boyce Equi[pment sent me one recently I hooked up the 468 wire but was looking at belt alignment , decided to start it to see how my belts were aligned and the alt / gen started smoking. dont know if it was bad or because the ground and #5 wire was not attached. they sent me a new one so I did not want repeat what happened?

It seems there would be a + by the one for #5 or a G or GRD or - by the other...maybe not...

I will have to see if there is a Prestolite in my stock...
