Qwik Posted June 10 Author Share Posted June 10 That was one of the initial problems I had. As I had neglected to install the ground to the engine cases. We ran an automotive battery that we had sitting close by thinking my battery was weak because it hadn’t been on charge much for the winter. It is now grounded very solidly. And still have the same issue of no spark. Quote Link to comment
DAZ Posted June 10 Share Posted June 10 (edited) So is it turning over properly now ? Or is it still slow cranking over ? With a car battery it should spin well ! Edited June 10 by DAZ Fat fingers vs small phone Quote Link to comment
DAZ Posted June 10 Share Posted June 10 When you say no spark ,none at all as in plugs out spinning over no spark or it just won fire up ? Quote Link to comment
Qwik Posted June 10 Author Share Posted June 10 Engine turns over strong. With a plug in one of the coils. And grounded to the engine. It has zero spark. I have tried with ether and regular fuel. And still nothing. I’m worried that the initial try where we had hooked up the car battery might’ve fried the pulse generator. Is that possible? Truly appreciate your help. Quote Link to comment
DAZ Posted June 10 Share Posted June 10 With ignition on have you checked power to coils , CDI ,etc and stupid stuff like side stand switch , clutch switch - though that's grasping as it wouldn't turn over if they were causing an issue , is it possible to check the pulse generator coil ? Should 135-200ohms according to some info I found on line hth Quote Link to comment
DAZ Posted June 10 Share Posted June 10 Also check voltages when cranking as if there is an issue with the starter circuit drawing lots of current it may affect the ignition side causing the lack of spark. Quote Link to comment
Qwik Posted June 10 Author Share Posted June 10 I will go back through and check everything. Didn’t know how to check the pulse coil. I will check that as well. Quote Link to comment
Qwik Posted June 11 Author Share Posted June 11 Everything seems good. I have power to the coils but no spark. Engine cranks strong and doesn’t draw much at all. Pulls it down to 11.7 while cranking Quote Link to comment
DAZ Posted June 11 Share Posted June 11 I'm at a loss if you've got good power to the coils then they're not getting the fire signal so apart from the signal generator and CDI I've no idea sorry maybe someone with a better grasp of electrics will chip in Quote Link to comment
george 1100 Posted June 11 Share Posted June 11 Sounds like either a CDI or earth problem. Test spark with an old plug first to eliminate chinesium spark plug possibility then go from there Quote Link to comment

Upshotknothole Posted Saturday at 06:22 PM Share Posted Saturday at 06:22 PM Engine was out of the bike, do you have the signal pickup plugged in? I'd start with pulling the cover off the pickup and working your way from there to the CDI and then to the coils and plugs. Hopefully it's something simple like that. Quote Link to comment
