Converting to a alternator
 

Hello, I was wondering if anyone has heard of anyone modifying up a car alternator to charge a battery on a Narrow Frame Cub, but using the start generator as a starter only????

Why would you do that? It already has a generator. No need for an alternator too. :Huh:

I looked at a 100 awhile back that a guy did it. He used a alternator out of an old GM car with a built in regulator.
I don't know why he did it, I didn't ask

Its possible to do. Very possible. But id look into just making the starter generator work correctly . If you do decide to use a alternator, a GM 1 wire would probably be the easiest to make work. Fabricating up mounts wouldn't be to hard either.

But it will gain you nothing except another part to fail, another belt to wear, another accessory to rob power..... and a complete waste of the time to build and mount it.....

Agree completely.... use working and/or rebuilt starter generators that will be olug and play will be the same price if not cheaper then the alternator itself

:IH Trusted Hand:

Would a Cub Cadet S/G have enough output to maintain the battery, power 2 forward facing lights, a back-up light, a flashing light and a small 12v heater to help keep the windshield in the cab from frosting up?

Depending on the lights and heater maybe

It is about amps, just add them up. For items that tell you watts, divide the watts by 13.8 (this is a decent average voltage for a charging electrical system. Remember that the PTO draws power too if it is on. You should stay under the rating for the generator. IIRC, the starter/generator/VR setup is good for 25 amps. Someone correct me if I am wrong on the amp rating for the s/g.
