First of all thank you for reading my post as I am pretty new to the snowmobiling community.
I have a 1984 Yamaha Phazer. Mileage was 8,900+ when the speedo quit working, yes the mileage is high but I take care of the sleds condition. My problem is the other day I went out and rode for the first time this year for a good 45 minutes or so. This thing did not skip a beat and it ran great as it did last year. It is when I got the sled into the garage to put it away for the night is when things got wierd. I went to shut it off by pushing down on the kill switch on the handlebars to move stuff around so that I could park it in the corner. It killed the engine as expected. As I tried to start it again, to move it it did not start. Why... well after looking at this, it had no spark??? I tried the kill switch many times of toggling it (pushing it in and pulling it out) with no such spark.
Here is my simple minded question, if I unplugged the kill switch on the handlebars and it does spark is it my kill switch? Does these engines run a open switch so if you do unplug the kill switch it will run with the kill switch unplugged? Meaning if you push it in, it grounds the spark and kills the engine?
I unplugged the kill switch, and the ignition switch and tried a known good used coil. No spark as of yet, I am new to this so I am learning as I am going, and right now... I AM NOT GOING... I am getting a new CDI module from a friend and I do have a spare primary and secondary coil ready to go for this engine.
As mentioned before, this ran flawlessly. lights were working and everything was as it was the last time I rode it last year...
Any ideas or help would be much apprechaited.

Yes to your question about the kill switch. The kill switch is open in the run position and closed in the off position. Disconnecting the plug should be the same as setting it to the run position.
Do the lights show any life when you pull the cord? It may not be producing any power (or at least not enough to spark), or there may be a problem with wiring or a component in the charging circuit. I know that this sounds like stating the obvious, but sleds of that generation are really simple, so don't be intimidated.
I would first see if it is still generating electricity when you pull the engine over without the coil connected. If it is then you may simply have a disconnected wire or shorted wire.
If you are familiar with basic electric testing, then just disconnect and start testing all of the components, starting with the easiest to unplug first.
We can get you all the specs.

Ding,
I know that I have no spark with the kill switch disconnected. This is with the ignition switch also connected. When the ignition switch disconnected along with the kill switch it still does not spark. Voltage to the orange wire while cranking (not starting with the electric starter becuse it is a starter type of PZ480) it will show mwe 2 volts while pulling over the cord.
Checked kill switch operation. About .03 ohms when switch is closed, and OL while the switch is open. The lights do not seem to show a glow while cranking, but I am not with the sled right now because it is at home and I am at work... I will check this out tomorrow.
Checked also the ignition coil primary. Orange to ground. .08 ohms. There was ohms with plug wire to plug wire as well. Either plug wire to ground was OL on the ohms too. That I know is working.
Quick question if you know. I got looking at this last night, the ignition CDI magneto has a white wire that comes from it to hook into the CDI box. The spare paerts that I have is from a yamaha SS440. Everything is the same but the magneto assembly does not have this white wire what is that white wire do for the phazer with elecrtic start?
I should also ask, what are some specs for this thing. Checking the CDI magneto and the cdi box? That would be so helpful if you have them and could supply them, that would be better. I think riding miht be a possiblity here within about a week or so, and i would realy like to get this thing rolling.
One last thing I should mention, is that with the starter capability of this machine, the battery is not hooked into the system. Reason why is a long time ago, my friend had a dead battery and took it out of the sled. He never put a new one into it. He rode it a lon time without a battery hooked in. I did too with no problems. Does this hurt the overall electrical comonents of the sled without a battery when it is supposed to have one installed.
Thanks again for your time to read this post...

First of all do you have a tether swich? My 84 Phazer dose. and when it whent bad I had nothing. if you do have one, unplug it ( should be able to unplug it from the gas cap.
Ignition coil testing
Check ignition coil primary resistannce as follows:
a. Swich a low reading ohmmeter to the RX1 scale.
b. measure resistance between the orange wire and ground.
Primary specs. Hitachi coil 0.14-0.17 ohms
Primary specs. Toyo Denso coil 0.11-0.13 ohms
Check ignition coil secondary resistance as follows:
a. Swich an ohmmeter to the RX100 scale.
b. Measure resistance between the spark plug lead and the the orange wire.
secondary specs. Hitachi coil 2.8-4.2 K ohms
secondary specs. Toyo Denso coil 3.2-4.8 K ohms
And to test the magneto:
There are two tests. one dose the pick up coil and the other dose the sorce coil.
Pick up coil: set the ohmmeter to RX1 test between the White/red and black wires coming out of the coil. resistance should be 15.3-18.7 ohms.
sorce coil. set ohmmeter to RX1 and test between brown to black wires. resistance should be 1.16-1.42 ohms.
Hope this helps you and good luck!

not as of yet...
I am going out there right now to look into this in more detail. So far, I have changed out my CDI module and ruled out my ignition switch, and the ignition coil, kill switch as well. I am ready to relook at the wires if all looks good, I AM GOING IN GUYS =0(
I have a magneto coil ready to go eventhough I don't want to do this. If all else is ruled out, don't you think that this would be the logical thing left to change? It sucks, and that is part of sledding, but it is fun... GRRR...
I will keep you posted.
Regards
Justin

I finally got this running again...
Guys, thanks so much for all your help. I got looking this after I speced a few things and changed my CDI module. After a no spark still was the issue, I then noticed my source coil ( the brown wire to black wire ohm check) had very high resistance. I saved a few parts from my SS440 and since they were the same coil, I swapped it out. That SS440 coil had 521OHMS compared to no ohms. I put it all back together and while getting everything in order I attempted to start it with no luck. That is the point that I got frustraed and mad. That is also the point where my woman said it was time to eat dinner for the night. After dinner I went back out there and overlooked as to why this was not sparking and you know, it would help if the kill switch was no on while trying to crank over to check for spark. I hit the switch and it is sparking and runs great.
I still am not sure as to why it was ruinning fine and as soon as I hit the kill switch it took out that coil, I verified wires and grounds and I am calling it a freak accident as to why that happened. But needless to say it runs great and the source coil was the problem of it all.
One last thing to note, is when I pulled the wires from the SS440 magento. I pulled the wires from the wire wrap that is that plastic stuff, and as I pulled the brown wire out (the source coil) someone had replaced the source coil at one time because the wire had black tape and not factory solder on it. But as I said since it ohmed out ok, I put it in with my magneto and all is well. I wonder if that was a common problem back in the day with these set ups?

Great news man !!!
Was it no ohms as in shorted out or infinity (open)?

If you have not checked into the problem with the speedometer, the most likely cause would be a bad cable. Phazer cables have a short life because of the bends they take. I have been through several on my 1985. Of course if you remove the core wire and clean and lubricate it periodically the life will be better. If it is not that, it may be the cable/key that fits into the shaft.
