Wires to LEFT COIL not firing 850

[tylerkilp]

83 GS850
They Wires leading to my left coil from the ignitor/CDI are not getting and spark. I tried the coil on the Right side wires and the coil worked fine. But the wires to the left do not seem to send spark . Any help would be much appreciated. I have not been able to find any wires or connections undone. Bike came out of impound and this happened. (damn cops)

First of all,


Next, there is no "CDI" on your bike.

That device is called an "ignitor", which is an unfortunate choice of terms, as it does not "ignite" anything.

There is no "spark" sent to the coils from the ignitor. The ignitor interrupts the ground wire to the coil.

Do you have a service manual for your bike? Most of them have tests to determine if your ignitor is good.

Hopefully it's just a connection problem......but, when you rescued bike from impound, did you jump it with running car?

had the same problem on my GS550. It's a bad igniter box. I'm installing a Dyna s ignition a DS3=2 for my bike. It eliminates the igniter box and is a dependable system. Doug

you can't assume that ..
there are many things that could be at fault here. pickup/connectors to the pickup/connectors from the ignitor to the coil.. corroded bullet connectors...
hopefully he doesn't need another system, but if he does then the dyna would be a good choice!!
