M1010 12 volt conversion

[rick martin]

Looking for some advice/help converting my m1010 to 12 volt charging system. My duvac went haywire overcharging the front battery. Already sourced leece Neville 12 volt alternator . Need some help with what wires to keep . Can't find wiring diagram anywhere I look. Thanks in advance.

Do you want to redo the entire system, or just the front battery?

Quite a few things require that 24V on an M1010.

Have you seen the Plan B thread?

I want 12 volt starter also I do not use any 24 volt. The box was gutted when I bought the truck.

No A/C either?

Ehh... well... Follow https://www.thetruckstop.us/forum/files/nn10.pdf as a start.. You'll obviously have to remove one of the alternators or at the very least remove the belt... The M1010 uses 2 -24V alternators, and not 2 -12V alternators like the other CUCVs, but you already know that

Look in the Plan B thread for information on how to disable/remove the DUVAC..
