this is my story too and i have a napa legend 65 battery under the hood and she starts over rough and sometimes needs a jump right off the starter like the starter gen is drawing power or isnt putting enough power to crank after siting a hour and i need to add leds and a heater but dont know if the led offroad lights 4 pct on Amazon would work?? so what do i do here the starter gen works and everything and the amp gauge says its charging but it seems to die help me out here. i do have another starter gen i could add to just charger while the other is just a starter. would that work??

The Delco-Remy S/G that IH used is rated at 15 Amps, which is about 200 Watts.

Not to mention that alternators look gaudy IMO on older tractors. (like when someone mounts one on the side of a farmall A)

My 72 has a broken armature, so the starter circuit works just fine but there is no charging to be had. I would consider an alternator only if I couldn't find another S/G reasonably and the one I have couldn't be rebuilt.

I've mounted a one wire delco 10si on about everything, even the driveshaft of cars, good for 40 amps or so. Even if they look gaudy, they charge a battery very well. Beats trying to find a positive ground 6 volt regulator for a allis WD.

Ok... so I'll play along.

Your choices are:
~Fix the S/G and charging system, try and get your amps down to run all the accessories you want. Perhaps ad another battery on the back (ugly in my opinion) to make up for the lack of charging power.

~Or, mount an alternator and do..... whatever your after.

Problems:
(I'm assuming we are discussing all this for the 126 you have)

I'm assuming with a cab, your running a snow blower, and you still have to have the S/G to start it... so, if you can mount it to the LH side, how are you going to drive it? Can't use the same belt, or it won't have enough contact area to start the motor and likely not drive the alternator. Plus, the muffler will kind of be in the way. Can't use the PTO because you might need it to run attachments. Can't add a pulley, there isn't room. PTO lever won't work then..... That leaves you with the pulley on the rear of the engine. The one used for a hydraulic lift. That, if not already in use, will work, but you are going to waaaaaayyyyy overdrive the alt. That takes power. Plus, they are only meant to turn so fast. You'll need to do some 'cifering to see how fast it will spin at WOT. Then mount it, and remember, you have a cab that is really close to that spot, so it's gonna be tight.

My opinion..... fix the original equipment. Forget the heater and mount a fan. It will keep the windshield clean. I have a cab on one of my tractors. Sure, I'd like some heat in it, but honestly, on a decent day, I open the rear window cause it gets stuffy in there. Your machine, your choice.

Thanks. Somehow I thought they were rated higher.

correct everything is for my 126 since it seems to be more work than just fixing the s/g explain to me how the starter gen has to jump off itself and not through the battery say like a car or a Farmall A. This has me puzzled. I don't have the patience to to put yet another harness in this tractor since it is brand new and all other accessory lights or on a separate harness to save the tractors harness from corrosion and splices. It really bugs me that it work fine then one day till present it just stopped working like it was no warning and it only starting because was on I can run almost anything on it so i know its charging ???
any help is nice but be in mind money is tight in these days . thanks in advance

I have two utility lights from HF that i mounted on hood hinge bolts with double nuts so they wont turn when the hood opens, and tail light and cig lighter in my cub. I have no trouble with my 1x4 starting or charging and i usually have my lights on and charging my cell while working.
