KINGJB

No that was legitimately was the first time it moved.

So we were going easy to see how it went.

I'm in the middle of doing a very similar build. This is sweet. Your gauges look just like mine. My motor and wiring is A 503 fan cooled out of a 1989 ski doo voyager . What is yours . What clutch is on the rear end and what width belt did you use . Ive put a Polaris ATV clutch on my rear end and the ski doo belt seems too wide

johnnyfkp

What shaft is the rear on yours? My club car has a ¹" shaft with 3/16 keyway. The clutch from the sled was splined, i have no way to adapt those so looks like i need a new clutch or clutch set depending on whats available. My motor is yamaha 500 liquid cooled, out of phazer late 80's i think

we used the original clutch for the golf cart. The belt is the 1 1/4? belt that was on the snowmobile it just barely fits on the cart clutch that is made for a 1" belt.

As far as the speed others were asking about earlier we got it up to 7000rpm. we have a few things slowing it down. one is the snowmobile clutch doesn't engage until like 3k. another problem is simply the gearing in the trans axle (12 to 1)

A shorter spring or heavier weights in the clutch will make it engage lower rpm, but it will not have any power down there. Try to shim or machine the secondary to fit the belt right, it should be at the top at rest and able to fall down in at speed to the right spot when the primary tops out.

Been a while since this thread has been updated. I have a question.

We are trying to figure out getting DC out of this engine. The engine produces AC, but no matter what we have tried, we can't get a rectifier to work right in this.

Anyone have any ideas?

It's been a while since an official update to this thread, so Im gonna take you all up to speed on what's happened with this build.

At some point the pull cord snapped, so we fixed that.



Something died in there




Cleaned it up





Put it back together and actually mounted the CDI box!



And did some more body work here and there



We also got a set of tires for it. They are just lawn tractor tires, got a good deal on em actually.



Here is are the tires all mounted up, and you can also see the progress made on the body, worlds better than when it started.



Stance is everything



Then after the winter, we started putting together the dash



wrapped the exhaust



And mounted a battery



Also made the electric start work, starts right up every time.








We took it out for some speed runs down the street a couple times. It tops out at a whopping 28 miles per hour. Feels fast when you're on it though.


My question about wiring in the rectifier still stands for anyone who might know, I'll take some pictures so I can better illustrate what I'm talking about.

KINGJB

I took some pictures to better illustrate what im trying to do with the wiring.

This is the rectifier regulator. It is this exact one. Hopefully there might be someone on here who can help.

The one plain yellow wire is the one I have already hooked.

This is where it comes from. It's the only yellow wire not cut off in this pic.



here is the other side of the harness



I have tried using every other available wire for the other side of that rectifier. None of them result in getting DC out of the center pin on that rectifier.

Now, this little black box is what used to be hooked up to that plain yellow wire.



I did a little searching and I assumed it was the old rectifier off the snowmobile

I have also asked about this on a snowmobile forum.

That is a voltage regulator. Mount it to engine ground and tap into the lighting wiring.
Unless your sled had electric start it did not have a rectifier.

KINGJB

It did have a electric start, we're using the same setup in the cart right now.
