No Spark on a 97 GSX,

[tjwool73]

Can anybody help me, I have a 1997 GSX. Three days ago I took the Rave valves out and cleaned them. Pretty they haven't been cleaned before. I put it back togethor and it fired right up. Went to put it in the water today and will only turn over. I put new plugs in when I cleaned the Rave Valves. I checked the spark plug wires and found I have no spark. Does anybody know where I need to go from there? Thank you

Pull the boots off of the plug wires. Trim them back 1/4" and re-install the boots. They just push and twist back on. Then give it a try.

I pulled the boots off and trimmed the wires, still no spark? What do you think about the coil assembley?

 

[JJinSC]

Have you checked all of your fuses?. Also, Make sure the plug wires are plugged into the high voltage box well on the other end too.

 

[tjwool73]

Fuses are good, I just ran the ski two days prior to the no spark issue. Where the plug wires plug into the high voltage box, is there anything there that might be giving me the no spark?

 

[JJinSC]

I had one cylinder I wasn't getting fire on one day after riding it for a while that day. Turned out that the wire was not plugged in well on the other end at the high voltage box.

Checked both of the plug wires going into the high voltage box, they are secure, and look good. Nothing was loose, I went back through the fuses and do not have any that are blown, still not getting spark??

 

[JJinSC]

Well it could be a faulty rev limiter, rotary valve clearance or timing could be off. Also, since it was running then suddenly stopped, might also suspect a loose ground or bad battery. Load test your battery and check all electrical connections and grounds.

Yes, load test the battery, put your voltmeter leads across the battery, what's the voltage? Now with the leads attached, try starting, now whats the voltage? If it's less than 10.5volts it's time for a new battery.

If it's not the battery, try this. There's a white wire in the rear E-Box that triggers the coil, it comes from the magnetic pickup inside the mag. cover. Use a test light, turn the motor over, spark plug wires disconnected and grounded, when you turn the motor over does the light flash or do you get voltage between the white wire and ground.

Something else you could check it the voltage regulator, disconnect the red wire, see if the ski starts, this maybe a long shot, but it's easy to see if it's the problem.

Lou,

I did like you said and checked the white wire inside the mag cover, I got no light at all, I also do not have voltage between the white wire and the ground. Disconnected the red and the ski would not fire? What do you think?

Also, Just relized I am not getting the two beeps when I attach the kill switch. Is there a way I might just have a faulty kill switch?

 

[LouDoo]

If you're not getting two beeps you might have a faulty MPEM, check the 5amp. fuse in the front EBox. Post back if the fuse is O.K. we'll go from there. If the fuse is blown replace it, there should be a spare fuse in the front EBox.

Went through the fuses, none were blown. All of them looked pretty good, even the one in the rear E box.

Lets try a couple of other things, when you put the lanyard on the post do the gauges light up? Also with the lanyard not on the post press the start button five times, does the ski go into diagnostic mode?

Lou

 

[tjwool73]

Gauges came on when I attached the lanyard, when I removed the lanyard and pressed the start button five times the gauges came on again, but I also got a "high temp" warning light, I have never got that before.

The good news is it sounds like your MPEM is O.K. The bad news is it sounds like the magnetic pickup inside the mag. cover has either come or needs to be replaced. It's not and easy job to get the mag. cover off so before we continue I want a friend, who is one of the big dogs on this forum to take a look at this thread.

In the meantime here's a write up on how to remove the cover.

Lou,

I really appericate all the help you have been on this. I checked out your link about removing the Mag Cover. Sounds like a little bit of work. It looks like you didn't need any special tools. I'll wait until you hear from your friend before I go any farther.
Again, thanks for the help.

OK... jut read it over... and I'm guessing that...

A) Your beeper is dead, and that's not good. That means we can't hear the error beeps if there are any.

B) I'm betting the pick-up coil has broken from it's mount... and that's why you don't have any spark.

 

[LouDoo]

Well, unfortunately it looks like I was right. You're gonna need to remove the mag. cover to checkout the pickup coil.

You've got a couple of options for the beeper, the best and cheapest is to get a replacement at Radio Shack, off had I don't know the part number, just take the old one with you, costs about 8.00.

Lou,

Been going throught the micro fish on this ski, and have a question? the following link shows the mag assembly and pick up coil, do I need to just get the pick up assembly or everything? Here's the link
