KarTek Posted May 15, 2013 Report Share Posted May 15, 2013 Hey, for reasons that will become clear at a later time, I have replaced the entire guts of the ignition system except the pickup coil and the spark coil. The new CDI is providing a perfect sawtooth wave 12 volt signal to the coil but the spark is weak to non-existant. Before I start checking everything I need to know if the coil is designed for 12 volts or something higher. If that's the case, it's working as designed and I just need a 12 volt coil. Thanks a lot!

toytech Posted May 15, 2013 Report Share Posted May 15, 2013 take the ends off the coil wires and check for corosion, the 90deg ends and corosion are the 2 biggest failures of a coil on banshee's. Quote Link to comment Share on other sites More sharing options...
KarTek Posted May 15, 2013 Author Report Share Posted May 15, 2013 The ends have been off and on many times but I'll give them a closer look. I'll also verify the ohm reading of the coil primary. Thanks. Quote Link to comment Share on other sites More sharing options...
KarTek Posted May 19, 2013 Author Report Share Posted May 19, 2013 OK, I checked the ohm reading on the coil and it comes out to .5 ohm. Is this correct? If so, my main question is still whether the coil is designed to operate at 12v or something higher. Thanks. Quote Link to comment Share on other sites More sharing options...
oldskool Posted May 20, 2013 Report Share Posted May 20, 2013 Have you tried snipping off a 1/4 inch of wire at boot. Idk just hope you figure it out soon.(MAY 31) Wish I could be more help, Quote Link to comment Share on other sites More sharing options...
KarTek Posted May 20, 2013 Author Report Share Posted May 20, 2013 I'm getting it sorted out bit by bit. Shoot, if it comes down to it, I'll just ride my F650GS down and mess around in the dirt on that! Quote Link to comment Share on other sites More sharing options...
KarTek Posted May 21, 2013 Author Report Share Posted May 21, 2013 Ok, your issue is you put a dc cdi on an ac set up. You need to get correct coils and also a dc/ac inverter to bump up voltage to a lot more than 12vdc. As 12volts isnt enough power to cross the gap. It takes 400volt to cross .001", 1000v to cross .006" and 3000v to cross .119" of air. Also, why did you do this? I figured it was something like that. I'm measuring the 12v on the input side of the coil, not the output side. I'm just doing this as an experiment in digital control ofver spark and such... Thanks.

KarTek Posted May 21, 2013 Author Report Share Posted May 21, 2013 Oh, I just noticed you're in Amelia, Ohio. I know a guy there named Tom Volz. Small world! Quote Link to comment Share on other sites More sharing options...
KarTek Posted May 24, 2013 Author Report Share Posted May 24, 2013 OK, still working on this. Tonight, I ran it and I noticed that one side is kind of "purring" at a regular rate when idling while the other side is popping and cracking. I switched the wires on the plugs and the problem switched sides so I guess I'm looking at a different coil one way or another... Quote Link to comment Share on other sites More sharing options...
