212 Golf Cart

I know this has 4 wheels but the build is in the spirit of what we do here. A friend gave me a fairly nice Ezgo cart that needed too much
to repair the electrics. Having a new 212 and torque converter in boxes its a no brainer. About a zillion of these have been done, but as usual
I opted for the hard way. Not wanting to build all the intricate structures most folks do I opted to use the case of the old motor. Required a lot of tedious, actually a little over an hour, cutting of the motor case. With the case opened I can run a drive shaft inside the case turning the original input shaft with Lovejoys being driven by a a chain from the Preddy. This keeps every thing in its original places drive wise. Much less complicated fab wise. And yes thats 1/2 steel I cut and hole sawed from the case. Speed calculations indicate a pretty good top end.

The brush holder now holds a flange bearing to support the shaft on the other end. Just waiting on Lovejoys now. Ignore the rusty parts, they will be handled.

To show the power of a 212 thru a converter this thing easily moves this 5x8 trailer around the yard. Starts easily from rest. I estimate the whole rig at 1500#? I use front spotting hitches to put my boats in the shed. The trees in the yard make it too much of an obstacle course for the truck. Its a mixed bag as there is no reverse, gotta hit it right the first time. This is largely an experiment as to the use of a 212 in a practical application. Its a Champ!

Now you got you a yard car!!! Handy for picking sticks up! I know mossy might have mentioned it early in this thread. But maybe if you do another golf cart, you can use 1 of the powersports gearboxes with reverse designed for the torque convertor. But it would be a more involved build for sure.

20A alternator ¿? These make life easier...

I have the dynamo basically worked out, just have to make it happen. Am still a bit confused about the regulator. From what I have read the dynamo makes DC voltage being permanent magnet while motorcycle type make AC voltage. The regulators I find are a AC, dont think they will work. The dynamo is basically a big version of a bike tire rub generator that runs straight to the application and its output is rated by its design speed. Am thinking I will run a 12v voltage stabilizer instead of a regulator in case the dynamo over volts.

When you get dynamo all fingered out, would you share your secrets with me. How its wired & items used?

Will do!

The dynamo is mounted and the wiring figured out. I had assumed the case would be in the circuit and the yellow wires
were for power. I wired it as such and got nothing. While checking the wires with a test light I accidentally crossed the terminals with a big flash, meaning i completed the circuit. So the two yellow wires are the circuit. If running non LED lights I dont guess it matters how you hook the wires up. Any thing taking A polarity specific hook up should have the wiring sorted polarity wise with a volt meter. Runs a good load at a 1500rpm idle. Plan to add a Voltage stablizer for a constant 12v.

So clarification on the charging system incase someone wants to adapt one to a build of something. Its a alternator, not a DC output generator as I was led to believe in a tractor forum. So its super easy to wire using a pit bike voltage regulator. This one In the pic.Hook the yellow and pink wires to the yellow wires on the alternator, ground the green, and the red is a regulated DC output, puts out 13.4v. You can run LEDs with this. Sorry for the confusion!

That is some great info.
