The battery connected to ground on its neg terminal is the 0-12 battery. The jumper from its + terminal to the neg terminal of the 12-24 battery(series jumper) is where you connect the 12v line. It can connect to either end of the series jumper(+ terminal on 0-12 or neg terminal on 12-24 batt) as they are the same point electrically.

Yeah, if that's the case I've seen it installed in several trucks.

He asked if it would work and we really need to know the alternator model number to confirm for certain.

you have to:

> slightly drill larger holes in the alternator ears (FMTV larger bolt)
> need to make spacers for said longer/larger bolt to hit both the ears which are farther apart than FMTV bracket takes. pretty simple>
> move the regulator however you choose..... I'd consider trying to keep it on alt body so regulators internal temp sensor is operating within the parameters it was designed. Most have not done that and been fine though.

Pretty straight forward thing.

I'm certain your assumption is correct, but he has not posted a pic of the alt placard/model number.

Are you confirming that that regulator he pictured is not used on any other Neuhoff dual voltage alt?
