    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.

In my quest to get my 1982 Suzuki gs750 road worthy I just recently changed my coils. I was stalling out once the bike got really warm and thought I was losing a coil. I did not however test the spark and just went ahead and bought new coils. No worries I am sure it could use new since they were the original so I am not upset about the expenditure. However I installed the coils yesterday and was still having trouble so I bought an inexpensive spark tester and lo and behold .. no spark coming from 1 and 4. I am going to switch the coils tomorrow to be certain it isnt the brand new coil. When I put the ohm meter across the primaries both coils read 4.3 ohms. I tried to get a reading between one of the primaries and the end of the spark plug cable but couldnt get a reading on either coil although I know one to be working so I must be doing something wrong.

Anyway ... I have read a dozen or more posts that make me think the next thing to chase down is the igniter or signal generator. I have looked in clymer and at the shop manual but the pix aint great and to be perfectly honest ... I am not seeing anything in my bike that resembles the igniter box??

I posted some links to some largish pictures. I do have some mystery relay looking box wrapped in electric tape but ... am I just not looking in the right spot. In all the images I have seen it looks like it should be behind the brake master.

The signal generators are easy. They are under the cover on the right end of the crank.

I do not see the ignitor in any of those pictures. There is a possibility that it might have been replaced with a Dyna system, you can verify by pulling the cover and looking at the signal generators. The Dyna system has the ignitor built in with the signal generators.

Based on how I read the parts fiche, the ignitor looks to be on the right side of the bike. After you find the signal generator where Steve said, try looking around the airbox area maybe?
