I recently got a small twin cylinder engine from snowmobile. I believe it's a rupp. I plan on putting it on a golf cart. I have it set in it and when trying to wire it I am lost when I came to the cd ignition box. It appears to have the number cu11 from kokusan denki. The only wires that arent connected to anything are a black with white stripe, a yellow and a white wire. I'm just trying to get this thing to run. Any help would be appreciated!

yellow is for lights, black is ground and the white is common to the cdi.

Ok, so black wire with white stripe goes to ground somewhere on engine and the white wire goes to ignition on ignition switch?

RJ Gleason

They go to a switch for run/stop.

Ok, so the black actually is the kill wire and the white is the power

Well I tried hooking the wires up the way u said. Didn't work. I put digital multimeter on the yellow and white and they ha .001 ohms to ground. The black with white stripe was like .885 to ground. I'm really confused on this and can't get spark no matter how I hook them up

kccats

How many groups of wires come out? If there are a pair of the same color wires those would be the lights (AC!)

What kind of motor is it im a rupp guy and have wiring digrams for ever motor rupp ever used

My ZR is faster then your ZR

Bleas

I can't find a tag on the thing, guy I bought it from said its a 250. I see the rupp logo down by the starter but no numbers. All the other wires that are on the engine hookup to something on the engine. The only three I have pig tails from are those three I mentioned. the yellow comes from down around the crank somewhere along with the white. The black with white stripe comes out of the cdi if I remember correctly

77zman

So its a l/c?

My ZR is faster then your ZR

Bleas

Sorry I'm new to the forum. What's l/c? Liquid cooled?

77zman

Yup

My ZR is faster then your ZR

Bleas

No it is air cooled

77zman

Can you take a picture and post it

My ZR is faster then your ZR

77zman

The only 250 manuels i got for rupp are for a single cylinder and a l/c. so i think that guy was wrong

My ZR is faster then your ZR

The cyl base should have a number like 248cc or 336 or 439 this would be the engine size.

Bleas

I can post a pic, it will be later today. And I will check the cyl base for a number

Bleas

Here are pictures of the engine and the wires attached to it.

77zman

Ok what you got there is a 1973 s-3 motor they never made those in a 250 they came in a 295 and 340 on the same crank and then 400 and 440 on the same crank it looks like it on a small crank ill get you a wiring diagram tomorrow

My ZR is faster then your ZR
