Attex Alternator

[Toys4Me]

I really like my Harbor Freight engine the only issue was with the charging system only putting out 3 amps. After some research and pulley calculations I managed to put an alternator in my thunderchief. Had an extra 1 wire marine alternator laying around. Used a 4" pulley off the driven clutch and the standard 2 1/2" vbelt pulley on the alternator. Picked up an automotive alternator adjustable bracket. Bent some steel to go over chains from the outside to inside frame rails, welded angle to that for the base mount of the alternator. Cut some angle to bolt the adjustable arm to. All this fits under the floor perfectly and should be protected from water and mud. Did I mentioned it actually works.

Nice installation. How did ya attach the 4" pulley to the driven clutch?

Picked up a longer 3/8"-24 bolt.

Will an alternator work spinning in either direction?? Just curious...

[BREEZE]

Yes an alternator will output clockwise or counter clockwise,,

Check the cooling fan. If the blades are angled it won't move enough air if it's turning "backwards".

[Toys4Me]

Its my understanding that spinning backwards will still cool.

i am hijacking the post. Hope you don't mind. I put a 63 amp. Alternator in my maxll. Took off recoil added a pulley. Plenty of room, works great. I set it up so that I can shut it off if I am not running lights or winch.

I was originally thinking that same route but then was concerned if I killed the battery and needed to start the engine it might be a little difficult without the recoil.

[tattooman]

Very good concern. I always have a spare battery and tools. I have never had to use it, but we all know if it can happen it will. When my Max is parked, I use a small float charger to make sure my battery is always maintained.

Toys4Me, is that a disc brake in the picture of your driven pulley?

[Toys4Me]

Yes there is one on each side of the trans.
