    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.

Bad coils?

So in my troubleshooting of my no spark problem, I tested the secondaries of both coils (between the HT caps) and they both read open...From the article I found, arent they both supposed to be between 30k-35k ohms?

The primary sides read 4.2 and 5.2 respectively. A little high, IMO.

I checked the signal generator resistance, and both were 163 ohm, so that is good. Once I figure out the HT coil issue, I can then test the igniter.
 
I just found out that both my coils are good! I thought that having both coils go bad is a bit strange. Both coils checked out at 34k ohms, which is still within tolerance. The culprit are the boots. I managed to get 2 good boots out of the 4, and checked the coils with those. Having said that, what resistor boots are suitable replacements for the bike? What does the resistance need to be? When I checked the boots, they were around 10k ohms.
 
What bike is this? It would be good if you put your bike model in your signature then when you post it will be there for everyone to see and it saves typing it every time you post.
 
5 ohm caps can be purchased at most foreign auto parts stores, bring your old ones to match up

My bad. Just added it!

What store are you referring to..?
 
So I did the test with the ohm meter to check the igniter, and it did not produce spark on either the #1 or #2 spark plug. I did test the coils by connecting 12v and temporarily grounding them to produce spark. It did spark, so the coil is fine. The signal generator's resistance is 162 ohm on both sets of wires, so that is okay.

I found the article on bike cliffs site about using two gm HEI modules for a gs1000g. Would this work for my bike? I noticed the guts of my ignitor are slightly different than the one in the tutorial.
