Will a 98 MXZ run if the stator is bad and not have any electrical working?

As I understand it, the short answer is no. Your problem would be the lighting coil. If the stator is bad you're not going to run or have lights or anything though these symptoms my be intermittent or progressively get worse.

I believe the stator powers 2 coils within the "stator assembly", a trigger coil and a lighting coil. The trigger sends power to the ignition and the lighting powers the lights and gauges and such via the v-regulator.

So, if you're running fine but have no lights or gauges, your lighting coil is suspect.

If you have lights while cranking/pulling but no or poor spark, your trigger coil may be the problem (not common).

If no light and no spark while cranking/pulling, stator my be the issue (more common then trigger coil).

Again, this is my simple understanding but I don't think I'm far off if at all.

Here is a link to a good read. There are others of course.

Good answer, David.

What could be making the lights not work? we changed voltage regulator and we tried the cdi and still nothing is there relays on this style and year?

A possibility, as I mentioned above is the lighting coil. If your sled runs but you are having lighting and/or gauge issues, your stator is likely fine but the lighting coil is suspect. Good luck.

the 3x4 box? tryed that

aduck · 11-13-2011, 06:36 PM

its in with the stator. thats your voltage regulator

**smallengineguy** · 11-14-2011, 06:07 AM

The lighting coil on the stator (under the flywheel) is bad. You'll have to replace the stator, since you cannot replace just the lighting coil.

thanks everyone we will test some more stuff

Ok since talking about stator's I won't start a new thread..

I aquired a 94 ski doo mxz 470 sled. it appears there has been some modifacations done to the handle bars. Anyways this sled has no spark..took the plugs out and they look good. tried the grounding the on the heads and no spark..trimmed the wires and still no spark..going to go and get new plugs and try that and going to test the stator also..does anyone have what the ohms should be on that paticular sled or is it kinda standard ohms for stators. Have watched the videos over and over on stators. fyi. just want to keep an open mind and not get focused on anything paticular..did that on another sled and went straight to the stator and it was not the problem..short story it was only a fuse.lol..thanks for any assistance...

**smallengineguy** · 11-15-2011, 06:17 AM

Unhook the key, kill and tether switches first. If still no spark, it's probably the CDI, not the stator.

fire_lt · 11-15-2011, 02:54 PM

Ok thanks SEG..also have checked out the other how to do and info sections you have done..great info n great help..thanks will report back soon...

zobenv · 11-15-2011, 03:11 PM

good luck finding a cdi box for the 470, i have a 470 and tried to get a spare but could not find one for under my first born

fire_lt · 11-19-2011, 02:03 AM

I got a chance to play with the ski doo and took out the tether switch and now it has spark..I took the carbs out for a cleaning and gonna empty the tank and that way have clean carbs and fresh gas..thanks again for the input.

fire_lt · 11-24-2011, 09:05 PM

Just an update..I got the 470 running and things are good..gonna probably have to look at the tail light and the headlight and see whats up with that..gonna check regulator..RPM's work but thats about it..just something else to tinker on. lol...

davidnnoah · 11-25-2011, 08:52 AM

Lighting coil/stator if it's not the v-reg. Someone is currently parting out a 95 mx on ebay.

While we're on the topic of stators, i have a '94' 500 Formula SL that when you get up around 65mph its wants to start loosing power and drops back to around 45mph. Occasionally it will kick back in and take off. I initially thought that it was a fuel problem and cleaned the carbs, no luck there, so I started going through the list. Both cylinders compression test around 125. I changed the CDI, same problem, rebuilt the fuel pump and resealed the motor, top and bottom end, that helped a bit with the idle but still the same problem. It reminds me when it looses power of a fouled out plug.
Could it be my stator or trigger?

on some engines you can unbolt the lighting coil from the stator plate cut the wires and pull them through the rubber groment . Then you can shove the wires from a new or different one through the groment and bolt the coil onto the stator plate and reconnect the wires . ive done it plenty of times on older rotax es and kawasaki jetski motors
