99' ZR700 Plug Wire Question. - Snowmobile Forum: Your #1 Snowmobile Forum

Hudson · 11-08-2012, 02:20 PM

Just pulled the sled out of the shed for the winter, and when i opened the hood i realized that the end of one of the plug wires was totally gone.

I look at it, and i don't even see like a metal wire core in the center of it. How would i even go upon repairing this? I have a set of old plug wires from the jeep that are still good. Could i take one of the ends of it and somehow splice it onto the sled?

I also found 3 wires that come off the CDI that aren't attached to anything, and were told that they go to the carb. Where do they go to? Anyone know or have a wiring diagram? Thanks.

You can buy universal ends that you put on. You won't be able to re-use the jeep cables, most likely those are one piece sets that you can't remove the ends from anyway.

For the plug wire I would first try and buy a plug boot that threads into the end, rather then trying to rig it.

And that heat senser isn't right neither, it should have what looks like a really small boot that slides over the post,

Images for 99 arctic cat 700 wire diagram, see if this will help.

Where would i buy these? Just an autoparts store? Any links or anything so i can see what they look like? I've never had to connect a spark plug wire before. Removed the end from the jeep cable and this is what i found. (Pictures below.)

What do you mean "threads in"? Any pictures or links or anything?

Once again, i'm over my head. What/where is the heat sensor, and what do you mean by "isn't right either"? Can i fix this or what? Which of my pictures do you see it in?

Most snowmobiles use a plug end that has a small screw-like connector that screws into the wire. The old plug boot will unscrew, trim the wire back a bit, screw the new plug boot back on. The plug wires are seldom wire any more, metal wire gives off a lot more radio frequency. Most are carbon centered.

NGK makes two kinds; a three-piece and a one-piece. The one-piece are really nice and would be my choice. This is what they look like

The picture you posted that says "normal??" On it, that's the heat/temp senser

So i just buy a new plug end that has a screw end and literally screw it onto the rest of the plug wire? When you say "trim" do i trim just the first layer of the wire or what?

Where do i even buy one of those ends?

Are you saying there is something wrong with it or that is where those three wires go?

Sorry for all the confusion and questions on my part, but i'm totally clueless.

Just cut about 1/4" off the wire, you can get the NGK plug cap about anywhere! I sell them about $5! I did see in the pic that there isn't a plug on the carbs!

Alright. I'll go look for one tomorrow at an auto parts store. They're just called "plug boots"? Just find one that screws on?

What do you mean there isn't a plug on the carbs? I'm illiterate.

ridegreen · 11-08-2012, 05:06 PM

Is this sled new to you??? Did you buy it like this

**kccats** · 11-08-2012, 05:06 PM

HPE sells them online! Look at the end of the carb rack! There is a 3 wire oval connector! That is a throtle position sensor!

Hudson · 11-08-2012, 05:09 PM

You guys are getting me worried with all these things you keep spotting that are wrong. I've went ahead and taken pictures of the entire sled, maybe one of you will spot something else that is wrong and i'll be able to correct it.

I bought this sled about 6-7 months ago from a guy who rebuilt it. It did run when i bought it, so it can't be too bad.

Bought it about 6 months ago from a forum member. Started up perfect when i bought it, but the recoil broke, and when i took that off, i broke the plug wire in the process. Just finished repainting the hood as well.

When he bought it, it had fire damage, and he fixed it up. I bought it how it sits. I'm assuming by your posts that something is wrong, and you can clearly see it, but i'm clueless and have no idea.

His thread is here when he bought it and had fire damage.

Alright. I just wanted to get one like tomorrow instead of waiting for one to ship in. If the parts store doesn't have one, i'll have one shipped in.

I was told that i didn't need the TPS for it to run. (Knowing about jeeps i know the TPS is pretty critical as it sends valve angle information to the CDI so it knows how much fuel to send.) I'd assume it has the same job in this case, but am not sure why it doesn't have one.

I'd also assume those three wires go to the TPS? Should i buy one and wire it up?

No not nessary, the wires must have been wired together? Take a look in the belly pan for that plug cap?

What does it look like? Just a cap that would cover that oval connector?

**kccats** · 11-08-2012, 06:18 PM

Just like the other plug wire!!!!!!

OH! Haha. Whoops. I thought you were talking about like a cap for the oval connector on the end of the carbs, not the end cap for the plug wire.

Apologies, i'll go look for it. Was there last time i looked. I'll even check the shed as that's where the sled sat.
