Coil problems HELP!

[96_yamaha]

Hi i'm new to this and need help with my banshee. it has had a problem with loosing spark. the last two times was with the coil. it has a moose stator in it, different cdi, and i just bought a dynatek coil but havn't used it yet (don't want to break it yet lol) also put in a different wiring harness cause the other one was messed with a lot. i borrowed a buddies coil after doing that and it ran but wouldn't kick start (i think that is because of carb adjustment and cold weather) but it ran than i gave the coil back and now my buddy doesn't have spark... anyways it i'm thinking about putting a ground strap from the motor to frame and also voltage regulator to motor to prevent this. just curious what other people think???? Thanks

 

oh and the frame was re painted so a grounding problem possibly??

ok so your shee had no spark and when you tryed another coil it started? then you gave it back and your buddy has no spark now? hhmmm maybe someone else could chime in because im lost it sound like your overloading the coil,

first, go over all your stock grounds and look for wire melting by the exhaust. there is an engine ground on the stator plate where the wires clamp on. and a frame ground back by the voltage regulator. and clean that coil mount......

I think you are on the right track. check grounds and "certainly" test for continuity from the engine to the frame. That is a common issue. The coil is very rigid and rare to fail. However, the termination points on the coil that plug into the wires commonly have issues. I recommend unclipping the wires from the coil, cutting a small length off the wires, and reterminating. Also, check those plug caps. They go bad and cost people all sorts of coin in new electronics they do not need.

Thank you for all of you who took the time to reply to this. But i did do something similar to what you guys were mentioning.

 

what i did was cleaned up around the frame mount by the voltage regulator and the coil, and made a ground strap from the biggest wire i could find laying around, i believe it was 14 gauge, and i ran that from the voltage regulator to one of the bolts that holds the cases together, and i also did one from the ignition coil to the case because i figured it wouldn't hurt.

 

It worked great all weekend for the radar run i went to. I took first place in both of the heads up drag racing classes i signed up for. so i'm happy with the dynatek system and having spark now.
