[Only One Coil Sparking]

Howsit Everyone,

I managed to get a secondhand CDI/Signal Generator and it fixed my problem. The Pickups was fine, measured 350 OHM between green and blue so I sorta thought it could only be CDI. Thank you everyone for your input. Really appreciate it. Now it is taping the whole wiring loom again, put everything back and go for a cruise

Hi,

I have gone through the complete wiring loom now from front to back. Can someone tell me if the igniter must be grounded to the frame. It seems like the guy that had the bike before moved stuff around. Should the actual igniter body be grounded to the frame?

Yes and No LOL! Depends if the pick-ups have a single or dual pick-up arrangement. If dual, the wires can be swapped over like the coils, before the 'CDI' - the problem should swap coils . . . . . . . subject to the wiring checking out ok! But pick-ups rarely are a problem . . . . . 'CDIs' on the other hand - based on age - quite often are suspect / fail and need replacement!

I managed to test the signal generator (Blue & Green) Im getting 350 ohm which according to manual seems to be fine. Do you think the only logical explanation left is the CDI. ?

HAve you checked the wires behind the right hand side cover al the way towards the igniter? Wires can break or get dislodged in their connection. 

 

Hey Blubber, Yes, I checked the complete wiring harness now. All wires seems to be 100%. I have gone through from below the tank all the way back to the back flickers and from the signal generator all the back up to the CDi. All wires are 100's. I also measured the OHMs of the  signal generator (I'm getting 350 ohm) According to manual that seems to be ok. I just don't know how to test the CDI, if even possible. That is the only thing left to my understanding..

Hi Poldark,

Thank you for the suggestion. I did exactly that. Cheers

Hi,

I have a Suzuki GS650GT and having problems starting. Only one of the coils are sparking. When I switch the wires over from the working coil (BLACK/YELLOW & ORANGE/WHITE)  to the non working coil (WHITE & ORANGE/WHITE) then that coil is working and the other one is not. So both coils are fine. I have gone through the whole wiring loom to check wiring and everything seems ok. I have done all the OHM tests on both coils and they seem to be ok.

My question is. Is it the the CDi (Ignitor) or the Signal Generator that is dead. if any....

You can view the GS650GT Wiring Diagram (in color) below.

Please.. Any help on how to diagnose further will be appreciated. Anyone that has maybe gone through  the same issue...

Thanks in advance
