Was riding and the positive post shorted out
melted positive post.
put new battery on it and fired it up. It ran for about 30 seconds and died. Lost fire . Turned out it fried the module had a crane 4n. So bought a brand new s&'s hi 4 put it in bam done the exact same thing idled 45 seconds and lost fire. Module is blinking when I turn it over. But no fire. No signalfrom the module. . 100 inch ultma on a 85 wide glide. Coil ohmes out OK. What do you guys think. Could it be the regulator over charging. Not sure how to check it. Please help

 

Did you do a resistance test on the primary of your coil? I would start it and let it run again till it dies and then see if you lose power 12 volts to the coil If you don't lose power to the coil then I would take pull a spark plug rested on the cylinder head with the wire connected and then do a momentary ground to the other side of the coil to activate the primary to signal the secondary See if you're getting spark at the spark plug... Keep in mind that the ignition is offering a ground for the coil to trigger the coil to fire once the ground is released the coil fires sort of like a capacitor..

I ran a small wire from the ground on the battery to the mounting screw on the module. I have both plugs out and and grounded good I have good 12 volts to the center post of the 3 post coil. It lights up the test light on all 3 coil pegs. I wired it exactly as the paper said to wire it. The only thing I deviated was the front and rear cylinder out put on the coil. That shouldn't make any difference tho should it? I sure wish I would have put a fuse between the hot going to the coil. I can't start it has no fire to the pluggs. Won't even tingle my hand I stuck my small screwdriver in the coil and held the bare metal with my bare hand and touched the primary and negative post with my finger while my cook whirled it over with the starter and spun it over by the back wheel in 5th gear without the starter and didn't get so much as a tingle out of the coil wires. Brand new s and s module. Do you know if this module can be sent to the manufacturer and checked I'm thinking about calling them and see if they might help or maby honor it somehow unless it is something that is causing it on the scooter . I have checked everything. Except for the output of the regular can't because it won't start and run. I'm thinking about throwing a points and condenser setup in it. Will my single fire coil work with points? Thank you for your help

 

done video test nadaa nothing no spark not even a tingle on my hand Nothing through to the plugs module has to be toasted? Damn damn damn.

 

OK just turned mypot from multi spark to single spark and it will bite like a toaster in the bathtub. . Goingto get a new coil it has a very small sign of opening up on the top seam. I will never wire another module without putting an inline fuse in between. Thanks for the help.

 

Once completed please post feedback.. thanks... A video of it running would be nice... Lol...
