  • conversion to an alternator ????

    What steps are needed to convert from a generator system on my '60 Lark 259 to an alternator system ??? List of parts needed ???...thanks...brad

    The easiest way is to use a GM Delco Remy alternator with internal regulator. Should be plenty of them at any salvage yard but you'll need to make a good stout bracket to hold it. Just off the top of my head I think there's three wires, a heavier output wire that ties into the the ammeter, a hot wire from the ignition terminal of the starter switch to excite the field and I think a ground. I'd have to look at my tractor to be sure.

      Well, you need an alternator and a mounting bracket. You may or may not need a new fan belt. You need to eliminate the voltage regulator if you use one of the self regulated alternators. Most people use the one-wire Delco, but a some say you are better off with one of the three wire setups, the Toyota and the Chrysler are recommended for these. Here is a link to the Toyota wiring diagram:
      I suggest you start here:

        What would be your purpose in doing this? I'm not trying to be a smartee, but a good working generator system does a fine job. If your current charging system isn't working correctly, the cheapest and easiest way out is to trouble shoot and fix what you have. An alternator system would only be needed (IMHO) if you have a much greater electrical load than the original car had, and/or if the car idles for extreamly long periods of time.

        Just my 2 cents.

          I agree with Dick. I have a generator on my 48 Champion and it works fine for my style of driving, However if I was doing a lot of around town driving at night( slower speeds) I might consider an alternator.

              Another good source of information is
              I used their kit on my 64 Champ installing an alternator off a 84 GMC diesel pickup.

              Basically the theory they expound is that one wire alternators work well for stationary equipment such as irragation pumps and on tractors with limited or no accessories, like one or two work lights. The article explains in great detail one wire vs. three wire. Both are internally regulated but with differnt attributes.

                I haven't converted one of my Studebakers to an alternator yet, but we have a 1954 DeSoto (6 volt) that is driven mostly around town and also used some for parades. We had a lot of difficulty with dim headlights and battery running low. I installed a single wire alternator (6 volt positive gnd) and the problems were cured. I am very satisfied with the results. Because of the single wire system, when first started the engine has to be speeded up a little to make the alternator start charging, but after that it charges continuously, even at idle speed.

                  My '49 2R17A fire truck came equiped with a 6 volt alternator and electric wipers. I guess the theory was the truck would idle a lot and be pulling a heavy electric load with the lights, radio, etc.

                    I bought a single wire 6 volt,positive ground, alternator for my 55. To mount it, I removed the U-shaped bracket on the manifold, flipped it around, drilled the hole larger for the 3/8" alternator mount bolt. Installed the alternator, used washers to align the pulleys and used the same, old belt and adjustment arm.
                    Remove the old voltage regulator, isolate and tape up the field and armature leads, then connect the alternator, BAT terminal to the "B" wire that connected to your voltage regulator and you're "good to go" ....
                    you're ammeter might need to be upgraded, depending on that amperage the alternator puts out.

                      I installed a one wire alt. on my 60 Lark 8 6yrs ago. 10 gage wire runs from the only post on alt to seliniod switch. If you want to see if it's charging use must use a volt meter,not an amp gauge. Run the wire from alt to one post on volt meter,then from the other post back to selinoid.
                      I used a bracket off of Stude 8 alt. bracket modified to line up with pulley. Real simple. 35k miles and no problems. Did the same on a 57 Broadmoor. Reason, in traffic at idle, the generator couldn't produce enough power to keep sanden 508 comp.engaged and evaporator fan going ,so the comp. would kick out. Installed alt.,problem solved. Generator doesn't do much at idle. That's me 20 cents worth. Thanks for letting me share.

                        I swaped my 60 Hawk over to a 63 style alt, and then over to a Honda
                        alt when the 63 style case broke. The Studebaker alts tend to break
                        over the years - good luck finding a replacement. This swap uses the
                        63 style alt mounting bracket.


                        Here is a link to what I posted years ago on the Stude newsgroup :


                        and the text :

                        Honda Alternator-
                        If anyone needs an altenator for your 63 to 64 Lark and Hawk, its the same
                        as Honda CVCC. Its about 30 bucks. It actually fits BETTER then stock, since
                        it has a sliding sleeve in the rear mount to keep from pinching the altenator
                        and braking the casing (anyone had this happen yet??) I can dig up the number
                        if anyone needs it .... it also looks simular to original.

                        The Honda one I mentioned is a direct bolt on with no needed modifications to
                        car or altenator. The wiring is easy also.

                        Power lead to power terminal

                        Field slip on connector to "F" terminal

                        There are two other terminals not used on a Studebaker. The Honda altenator
                        used a dual amp VR. So it had a high side and a low side. We are only
                        interested in the high side or 35 amp. Which is the "F" terminal.
