    A note to old forum members...
    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...

  • Returning Visitors

    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.

This may sound very dum, but bear with me. on the 1983 GS 750, I have a shop manual and an owners manual, they mention coil -coil related language, but none of these mention the location of the coil. I think i know what the coil looks like, but so far I have been unsuccessfull to locate it.
Also, how do you check if the coil is half bad?
 
Re: coil location

Remove your gas tank. Look at one of your spark plug wires. One end will have the spark plug on it, follow the wire to the other end. The large cylinder it comes from is the coil. The coil is either good or it is bad. It cant be half bad. That would be like being half pregnant. :-) :-)
a multimeter is required to check the coil resistances. Resistance across the secondary terminals should be 3 ohms. However, anything between 2 and 5 ohms is acceptable according to the Suzuki service book.
Primary resistance between the spark plug leads/caps should be between 30k and 50k.

this is what I got:
coil that has spark plug # 2 and 3:.
primery read 4.1 ohm
checking the plug caps as secondary resistance read 60 k

coil that connects to plug 1 and 4

primary read 4.1
secondary read: zip, zero, zilch
so what does this indicates, can I replace the caps separate or it would still be the coils?
 
Make sure the plug caps are making a good connection. They unscrew off the wires. Cut back a little of the wire and screw the caps back on. After that if you still get a reading of zero that coil is bad. The 60k reading is a bit high but you can probably get away with it. That could change as well just by making sure the caps are making good contact.

I just want to thank you all who responded to my request for help, and I feel like I have the greatest expert mechanics in the motorcycle world, but more then that great people willing to help another person.
It is great to be part of this group
Keep up the good work everyone.

Ard :D :D :D
