You will have a total of 4 wires going behind flywheel, one comes up and attaches to the SSI module, that's the feed wire to give it the juice to create fire. 2 together are charge wires going to the regulator, then 1 other should go up to switch which is kill wire.

 

I correct myself, the 10 amp system does have 12 poles or fingers, but only one is used for the ignition not 2, other 11 for the charging system.

Oh, and the flywheel magnets can be glued back....don't ask me how I know :wallbanging:  :wallbanging:

 

I have actually dissected a module and was going to follow Ed's instructions by still using it for a pickup signal and use the Chrysler controller and coil, but decided to get away from the battery ignition. Was going to try to do it for under $50 :rocker2:  :D

Ok so I've done some testing. Magneto seems to be bad. Alternator has a chaffed wire on the inside of it. My buddy is going to bring it to his school and see if they can replace the wire, and see if they can fix the magneto. My question is what is the red kinda fuzzy wire that my buddy is holding? It is somewhat messy and def seems like it shouldn't be like this.

Where did you find the fuzzy wire?

In the first picture you can see the top of it at the 12 o clock position. It was behind the alternator.

Definitely not suppose to be there, must of got caught in there some how while the engine was running.

Might be all that's wrong with it, remove and try again. ???

Yea i don't know where it came from. Not in the parts manual. lol we tested the magneto and got 0 OHMS. And there is an obvious chaff on the kill wire on the backside

I think Like Doug said, that fuzzy wire got sucked in or mice were starting to make a condo. I agree I would put it back together and see if it will spark now.

Another thing, Is that actually wire (some type of metal)? And do you have the manual that shows what you should be reading when testing the different wires?

It seems like wire. almost like an SOS pad. I'll take a closer look tomorrow. Negative on the manual for testing. I was going by TAHOE's suggestion. My buddy even thinks it's gone bad.

I just got another one running 2 days ago, that the previous owner thought the SSI unit was bad, (no spark) All I did was clean everything good, The magnets, stator and the SSI unit. I made sure the 2 pins were at the right hight. I then put it all together and set the gap for @ .008, That was for the large pin to the post on the bottom of the SSI unit. I cranked it over and had a great looking spark. After I put the carb on it fired right off and runs great.

Here is the manual in our Manual section. If you can download it. the procedure is on page 45 of the manual, it shows page 47 in my viewer.

I would have to go out and see, but this is NOT a magneto... And does not measure as such with an ohm meter.

This is a CDI. The C stands for capacitance and an ohm meter will not work for a true reading on a cap. Sometimes, you see guys using a std VOM on a cap, but they are more or less testing the cap for a short...which is a bad thing. You don't want shorts.

I will go get my spare, take it with me to work and test it today with a VOM.

I would agree, that wire stuff should not be there, not sure how that got there but somehow got sucked up in the flywheel or some little critters pulled it in the general area, then sucked up.

You have the 10 amp charging system I see. You got the bolt on magnet ring too, shouldn't have to worry about them coming off.

Yeah, there is real no way of checking the SSI module ( not a magneto) with a meter. While mounted, you can check resistance of the spark plug wire red to plug wire, black to block, it should range from 4000-7000 ohms. They sometimes get a break in them or pull out of module, but no common.

You should get around 115-170 ohms in the wire that came up and hooked on side of module ( one of left in the first picture), that is the feed wire.

Short pin should be .187 high, tall pin should be .250

Download the 8-18HP tecumseh manual, it's a life saver.

Also, look at Ed's website,  www.enginesandmagnets.com  he shows how to test and records what all values should be has real life pictures so you know exactly what to look at. I've learned a lot from reading his stuff.
