ground wire

[Chris the sled guy]

So I got my engine back in and can't remember where the black ground wire hooks to the engine. Any one wanna help me out?

Is that for a boondocker box? Or did you add a ground?

If it is for a boondocker box or a TFI it goes on one of the pull start bolts.

I'm guessing it's a ground. It is a stock sled. Black wire with a big round end on it comes around oil tank on the mag side just not sure where it goes.

 

[Z-Man]

Factory grounds are brown.

What does the end on that wire look like? Is it a big plastic piece?

 

[Chris the sled guy]

So it looks like there are two wires bundled together at one end and a about one inch round plastic with brass in the center at the other end. What is this and where does it go?/???

I think you are looking at the knock sensor. It bolts on the underside of the head on the back of the motor. I am trying to find a photo for you.

 

[Z-Man]

Does it look like this?

 

[Chris the sled guy]

Yep that's the one...

 

[Danbot]

Yeah that's your detonation sensor. It bolts on to the underside of the back of the cylinder head.

 

[Z-Man]

Found it. I knew I had a picture somewhere.
