Thread: Wiring harness diagram needed for 460 with dual batteries and single wire alt.

    I have a 1979 21' Southwind that I am restoring with a 460 that I just finished building (What a difference). It has a single wire gm style alt. and one battery currently, Would like to install a perco dual battery switch and second battery soon, But want to build new harness first and a diagram of some sort would be great.
    My email at home is tcooley@houston.rr.com
    and at work is tcooley@shellus.com
    Any help is greatly appreciated.
    Thanks,
    Tim

    it's been awhile, but i put dual batteries and a perko switch in a party barge i used to have .. as i recall the existing battery cables from your motor hooked to terminals on the perko switch, then battery #1 and battery #2 hooked to their designated terminals on the perko switch .. presto, schazam, abbra cadabbra! no new harness required :-)
