  • Back-up Plug-n-Play Alternator

    Well, after experiencing an epic fail of my "Alternator in a Can" I decided that a plug-n-play replacement was needed. So, after a Pick-yer-Part trip, I start thinking how to do this and NOT need any more tools than necessary to remove the "Alternator on a Can".

    Simply done is my goal, so I look through my bar stock bin and since I don't usually deal in steel, I decided on brass, but the 1.185 wide by .250 thick didn't seem stout enough to simply do the trick with needing a ½x20 threads. Something was telling me that I would need at least ½" worth of threads to make it work. So, I superglue a short piece to a longer piece, drill 3 holes and install 3 3x35mm flathead allen screws because that is what I have laying around. No need for anything larger as they are only keeping the two pieces together long enough to drill and tap to the ½x20 hole. As you can see by the pictures below, a bit of paint and tadaa!

    Now, using a long 3/8x24 bolt, drill alternator mounting hole under-size and press the bolt into the mount., this way I don't need to hold the bolt to tighten the nut holding the alternator in place.

    Now, just a simple slide on of the alternator and the nut and the adjusting strap, hook up the wires and done.

    So here is the GM alternator installed right before running the wires and adjustment strap off the timing cover. I know you all have seen this before, but hey, here it is again.

    You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

    Nice job planning... It always pays to be prepared and that looks like a very easy roadside change over

      I think I am going to change the mounting terminal for the wires to atop the alternator. Just been sitting here thinking about that.

    Your Powerhouse CAN could be converted to a COOKER, "JUST SET IT & FORGET IT":rolling

      You could probably make a round sheet metal cover front and rear and mount your powerhouse end cover to it. Chop that ear off the top. Make it out of aluminum to dissipate the heat...Put a dummy cutout on top. I've thought about that at times doing it to mine. Glad I didn't throw out the old Ford script cutout on my old genny.

        I like it, heading to the workshop as soon as I finish my coffee. What kind of cooling fan & how well does it work? I don't see a shroud though. Bob

          To be honest, I am less than satisfied with the fan I run. I am looking for another 16" fan that doesn't draw 15amps! You would think in these days of brushless motors they would make one power efficient!

        'Exciting' the alternator.
        by Michael M
        usually a quick goose of the gas would get the alternator in the charging mode. Lately, however, I find that it takes a few - or several - high revs to accomplish this. Then it charges as normal.

        is this the beginning of a problem?

        First Model A - New Alternator & Fuse issue
        by mjgravina
        Hello Everyone,

        Hope you are doing well. Me and my dad got our first Model A, it's a 1930 Tudor Sedan beauty.
        Just a couple of weeks into our journey we ran into the first couple of adventures, and wanted to use it as a chance to introduce ourselves and get some help, as well as contribute whatever little we know.

        Car battery would be drained every morning. Figured...

        Alternator Magnetism Flashing
        by Bill G
        I had mine sit for about 9 months once and when I started it back up, I got nothing from the alternator. Mine is a NuRex alternator 6v Positive ground. I have no idea what alternator you are running, but at the time, I wrote to NuRex and here is the answer I got back. Once I followed this simple instruction, the alternator came back to life:

        I'm in uncharted territory.
        by Blown Gasket
        I rewired the ignition today, replacing the broken junction box and one ton of electric tape, plus reversed the wires they had backwards. Did the gas gauge but I had neoprene gaskets not cork, I'll have to order some. Then I got to looking at the new steering column bracket and had to stop and call for help, HELP! BTW the original was leaking but not now, strange?
        I did many searches on line...

        How to Identify an Alternator
        by JKY
        I got a collection of part with one of my car purchased. Among the group was a Delco alternator. Is there a way to tell if it's been converted to 6 volt positive ground short of installing it without connecting the wires and testing it that way? Local auto part stores are stumped and can't just spin it for me (tester requires the cover to be on before you can spin it). I thought of running it on...

        New alternator issues (help)
        by Steve from FL
        I have a 1930 model A and recently installed a new alternator. The previous owner converted the car to 12v. The car started fine a few times then the battery went dead (brand new battery). This leads me to believe that I wired the alternator incorrectly. Here is a picture of the setup. the red wire goes to voltage. Im not really sure whats wrong with it. Electrical is not my specialty. I have also...

        Fuse Holder Fix
        by DaWizard

        Ok boys and girls, as promised here is my fix for the Vintique fuse holders...

        If you carefully take apart the big end you will note that the only thing that keeps the bolt from grounding out to the plate is air squished between the two plastic washers. I guess 2 step washers wasn't in the budget. Well, to me, this is totally unacceptable, so I do something

        Alternator in a Can, or How to fool the judges and run 12v.
        by DaWizard
        Since I have been boasting about my 12v neg system I was told I needed to do a pictorial and text of how and what I did to get my "Alternator in a Can" or "How to fool the judges and still run 12v". So, you asked for it, and yes, I am going to get winded.
