My regulator recently went on my bike taking the ignision fuse,batt, and fuel pump relay with it. i have replaced all three but for some resson i now have no sparks/ or at least no power going to the sparks.

i have checked for dogy wireing and ive had a look at the coils but they seem to be fine. is there anything else that would course the power shortage to the sparks?

im going to look at the "spark unit" today but i read that it can only be tested by a professional.

Any help would be great cheers

 

do you have a manual and a multimeter? how do you know your coils look fine internaly?

for starters, battery voltage needs to be atleast 12 volts. below that it might still crank, but sometimes you wont get spark.

there is also a pulse generator, the manual gives specific ohm resistances to check for to determine if this is bad.

also, did you check for spark at all four spark plugs?

 

There is also a 10A fuse in that circuit. So check all the fuses.
