page 6-7 0f the ssm has the resistance chart for the ignitor unit..
can post values later if you need them

When I lost spark I swapped out the coil and CDI and still got nothing. I had to replace the signal generator (part of the alternator).

I just looked at Clymer's and they call it a "pulse generator," a "signal generator," and a "pickup coil." I assume these are all the same thing? The part that sits beside the stator under the left cover?

Clymer's also states "The signal generator is part of the alternator stator coil assembly and cannot be replaced separately. . . . the stator asembly must be replaced . . . "

Did you replace just the signal generator or did you replace the entire stator assembly?

BTW, Clymer's does have a test and says the resistance should be between 200 and 240 ohms. I will go out an check that in a little bit.

Thanks,

Mike

Just checked the resistance and got 230 ohms, right where it should be. I also checked continuity from the plug to the ingnitor plug and it was good as well. The signal generator does not seem to be the problem, for better or worse.

Those values for checking the ingitor would be appreciated! Thanks.

At least, one by one things are getting narrowed down.

Cheers,

Mike

Yes, the tester I have plugs into the spark plug lead on one end and clips to the cylinder head (or anyground) on the other. There are two screws in a plastic body and you can open or close the gap between them. When you turn the bike over you can watch the spark jump the gap and it is easy to see against the black plastic body. You can open the gap and see how far the spark will jup as a guide to how strong it is. Very handy tool, available at any auto supply store. No need to hand on to that spark plug anymore. I did have a brand new and correctly gapped plug in the bike when I was turnign it over, btw.

When I tested mine I got a spark, but just for an instant, which jumped a very short gap. The spark was not bright blue, but rather weak looking with tinges of yellow. When turning the bike over, as long as you keep the starter button depressed you should see the spark, but mine lit once and was gone, the starter motor whirring on by itself producing nothing.

Do you have the testing numbers and procedure for the igniter unit? I sure would like to confirm it's bad (or affirm it is good) before turning over some serious $ (for me) for another.

Also, I see that later models have a different igniter, at least the connector looks different. How specific to the year of the motor are these? Can I use only one from a '86 or can I use one from a later eyar or range of years?

TIA

Mike

You da Man! Thanks a lot! I will go grab my tester and check it tonight!

Cheers,

Mike, who owes you a beer

I got nothing like that at all. And they were inconsistent to boot. Here are my results roughly (last column).

Guess I will take the unti to Suzuki if they give me a fair price for testing it, just to be certain I have not screwed up somewhere in my measurements. I found a couple good candidates on ebay. Not the exact year, but they both are the same style.

Thanks, everything else I have to go on gets me closer to riding.

Cheers,

Mike
