    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I was riding my 1980 GS750LT last fall, when it sputtered a few times, then died. It would not restart, or even fire. I had to trailer it home. I finally got around to working on it a month or so ago, and found that I had spark on #1 & #4, but not on #2 & #3. I thought the coil was bad, so I took it to The Rice Paddy in Columbus, Ohio to get a used one. They tested mine, and said it was good. Later, I tried another, with no spark. I made jumpers to connect the 1&4 wiring to the 2&3 coil, and got spark. I have checked the continuity of both wires going to the 2&3 coil, and both were OK.

I checked the resistance of the signal generator, and it is in spec.

I did the ignitor test using a 1.5V battery, and got no spark from either plug wire (3&4).

It seems like the ignitor is bad, but I'm hesitant to buy one without knowing for sure. Anybody have any thoughts? Thanks.
 
You need to replace the signal generator as the 2/3 pickup has gone bad. I would recommend you just replace it with a Dyna S plate & be done with it! Ray.
 
Just buy a Dyna S ignition for it. The Dyna replaces the stock crankshaft triggers and the stock ignitor module at about 1/3 the price of stock parts.
(the stock crank triggers and ignitor go directly to trashcan :-) )

If you conclude that you need an igniter I have one that will work on your bike.
 
I'd like to fix the bike spending as little money as possible, as I'll probably try to sell it soon. I may try to find a replacement signal generator first, as it is less expensive.

If I go with the Dyna ignition, is this what I need?

Thanks for all the replies!
 
I got the bike running, and despite having sat for about 8 months, it' s actually running pretty well (after I remembered to put the air box back on!).

Bill (chef1366) sold me a used ignitor and signal generator at a very good price, and shipped it very quickly. I installed the ignitor first, as it is the easiest, and it fixed the problem.

But, as my luck goes, now that it's running, the starter button quit working yesterday! I haven't had time to look at that yet.

Thanks again for all the help.
