Alternator vs Generator

Discussion in 'General Amphicar Discussion' started by dougparsons@ameritech.net, Mar 21, 2001.

  1. Ok swimmers its spring again and we are all working on the Amphi's

    I have decided to go with the Alternator after having some electrical
    problems last year. I have it all apart and I remember that there was
    a web page with all the how to for the conversion but,I can't find it
    again (or maybe I was in some amphi dream).

    Has anyone done this and is there any instructions beside the fuel
    gauge and sending unit?

    What about the wiring on the volt regulator etc. Windshield wiper
    motor?

    I know Scott talked about the Gm 60 amp single wire is this better
    then the spitfire alt.?

    What about the starter is there anything that needs to be converted?

    Which wire goes where :cool:

    Any help will be appreciated.

    Thanks,

    Doug

    Doug,

    This single wire system is negative ground based. You must change from
    the factory positive ground to negative ground.

    http://www.vtr.org/maintain/negative-ground.html

    The starter does not care which way it's hooked up.

    I found after three blown fuses, that the pin that holds the contacts on
    the wiper motor closed short to ground. I glued a piece of plastic to
    the spot where the pin pushes on the contact. Problem solved. While your
    in there you can fix those wipers that stop in the middle of the
    windshield when you turn the switch off.

    Oh ya, one more thing I just found after some wet feet swims. You have
    to change the BILGE PUMP wires around also. My Walmart special was
    running backwards.

    Take a GM alternator from a 74-83 car to your favorite shop. The guy who
    did mine said it did not even have to work. They replace all the guts
    and use only the case. It cost me $42 for the conversion to a single
    wire alternator. The new regulator on it's own is about $15. The farmers
    are buying these things like crazy for their old tractors. When the car
    first starts the alternator is off. A rev up to about 800 rpm and the
    unit kicks in, runs even at idle. 14.7 volts

    I think these two projects took about four hours total. three and a half
    hours of which were making the top bracket for the alternator.

    Doug, et al.:

    In response to the posting below, David Chapman's page at
    http://www.amphicars.com/actgen.htm briefly describes the generator to
    alternator conversion process. One can also mine through almost 40 or so
    past postings to this List concerning "alternator" (also "alternators",
    "alternater" [sic]) by clicking:

    http://www.escribe.com/automotive/amphicar/search.html?query=alternat*r*

    or, do the same sort of search for "generator" (also "generators",
    "generater" [sic]) by clicking:

    http://www.escribe.com/automotive/amphicar/search.html?query=gen*r*t*r*

    You will find David Chapman's fairly definitive posting to this List on this
    topic through both of the above searches, or you can view it directly at:

    http://www.escribe.com/automotive/amphicar/index.html?mID=479

    One of these days I might do the same swap.
