Alright, here goes. Bought the machine knowing it had an electricla problem. Guy before me never got it running but damaged the ignition timing sensor. Replaced, machine ran like a top-------------for awhile. Next, machine would start but only idle, throttle would only try to kill it. replaced battery. Machine seemed to run well for awhile. then died on trail. found battery to be very low. Charging system not seeming to work. machine would run great sometimes for a few minutes then die. Sometimes it would show charging, other times no charge or very little. Found that when it tried to die, I could pull the 15 amp battery charging fuse and it would then run normal. If I tried to put fuse back in, it wanted to die. wait a few minutes and boom, I could put fuse back in and it would not die. I have check grounds, coils, and spark. The lighting coil output only seems to be about 2.5 amps with no change regardless of rpm. The problem is obviously intermittent. could it be the stator or the CDI?

Supposed to be a 10 amp fuse in there.
If you are having charging problems, I'd guess that the regulator is not functioning properly. Check that it is grounded well (bolt not rusty and use dielectric grease between (aluminum case) it and the steel).

Isn't there a different Regualtor / Rectifier on the older batery type EFI? Perhaps someone put the wrong one in?

aquaman40

My machine has both a voltage regulator and a voltage rectifier. While messing around, I noticed a little smoke coming from the rectifier so i replaced it, burnt spot found on the back. I also swapped out the regulator with one from another one of my machines, same one, The fuse box indicates that it is suppose to be a 15 amp fuse. It's almost as though when the fuse completes the charging circuit, the engine cannot handle it and dies. If I quickly pull the fuse out, the engine remains running. Other times it has no affect wether it's in or not.

Try it with a battery charger attached so there is no load on the charging system? You may have a weak stator?

aquaman40

I have tried using jumper cables but the strange thing is, it will not even try to start with jumper cables attached from another battery. If I swith batteries, it will start and run for a few, it's almost as though it resets itself for a breif moment. I have not tried to run it with a battery charger attached. Should I try it with the battery in or out. And should the charger be st to 2 amp, or 12 amp when I try. I will have more time this weekend. It's a good thing I have other machines, because the snow here in Northeastern Ca. is great. Thanks for your time.

kccats

Try it with the battery in and on 12 amp!

RJ Gleason

Which model is this? I can look it up then.

My machine is a 1995 Wildcat 700 EFI. Seems like it acts normal until something gets warm and then it starts messing up. Could a stator be sensitive to engine heat. I'm really starting to think it's the stator, I have read several posts that say stator problems can be intermitant.

kccats

Yes that is exactly when it acts up, a small short that grows as it gets hot! Call the stator guy! If not I have one from a 92?

aquaman40

Ok I just bought a used stator off of ebay. I sure hope that cures my problem. I will keep the thread posted once I get it and install it. Thanks for all of the above advise.

aquaman40

Update, installed another stator purchased off of Ebay yesterday and have the SAME EXACT PROBLEM. Anyone have any dynamite?

kccats

I heard they make 1/2 sticks, that aught to be enough and will fit in the gas tank!
I don't think the cdi would be it, they're either good or bad, besides they wouldn't heat up with the engine, could you have gotten a bad one? Call the stator guy from the parts link and ask how to test or if you can send them in to him to test!

aquaman40

is it really possible to get another stator with the same exact problem???? By-passed the tss, not the problem. Machine will just not run with the 15 amp battery charging fuse in. Pull it out it runs fine, so much as touch the contacts with the fuse and it want to die. I'm thinking that maybe the used voltage rectifier is bad, I don't know. I'll keep trying.

My 1996 ZR580 EFI has very similar issues. I think I've narrowed it down to ignition. I just pulled my coil and found the resistance between the two secondary leads is over 16K ohms. The spec is 6.3K ohms. I also checked the primary lead resistance on the coil and it initially shows .7 and then after 5-10 seconds it goes to .15 and the spec is .3 ohms. I think I'm onto something here.

paintballdude05

^^^ Coil is probly not bad here. You're getting 16k ohms cause you probly did not take off the caps(5k caps x2= 10K). I was gettting .7 adn stuff and was told it was ok. Best bet swap it with a good one.

aquaman40

I have another coil on it's way, will get it in this weekend, also looking for another rectifier, maybe the one I got was no good. I'll keep the thread posted.

schusterjo

I have the exact same sled...
Almost the same issue but not exactly... mine will not keep the battery charged is all.. I charge it up and ride for about 3 hours then it will not run.. Put a different charged battery in and it runs fine till it goes down..
I will be interested in what you find out is wrong with your sled..

aquaman40

Sounds like your only problem is the voltage rectifier. If it's bad, the battery will not charge. You can put a voltmeter on the battery when it's running and see if your getting somewhere around 13.5 volts. Mine won't allow me to put in the 15 amp charging system fuse when it's running, (causes it to die). I'm almost at my wits end, waiting for a coil and looking for another rectifier and cdi.

schusterjo

Well I have been reading for several hours now using Google and I found a lot out.. 1995 wildcat 700EFI like I have has somewhat of an issue far as this little problem goes...
It doesn't have a battery-less EFI, another words the EFI is constantly pulling from the battery.. Hard on it and you should keep a decent batter in it...
From what I am getting a good one will last about 2 years.. I didn't even really look before I went and bought one and ended up getting a small one...
The recommended battery is
Deka ETX18L
Get that and they say you will not have issues with the batter for a good while.. That's probably my fix...

Your sled
Well I have read overheating of the stater on a few post..
throttle safety switch/kill switch causing some people issues like yours..
And basically what you already have checked....

Not much help for you...(really been looking for my issue)


Now I just need it to snow dang it... only had it out 1 time this year.. I keep looking out the window hoping for a blizzard.. My girl thinks I am crazy

The time I did spend riding was the most fun I have had in many years.. Sad but true.. I haven't rode a snowmobile since I was a kid and it was a bombardier 440 i bought for $200 back in the day.. Had it 1 year and never really got it to run correct...

One thing is for sure I am hooked now and probably will be getting another newer sled to come..
