I replaced my coil on my 79 shovel engine because of weak spark thinking that was the problem, but its still weak, the bike won't start, has new battery but can't check under load cause bike won't run, what should I check next, plugs are new but plug wires are old but check out OK with multi meter continuity? Any help would be appreciated.

 

I replaced a few expensive parts before figuring this one out LOL! Expensive lesson

 

wow I had fire under my seat until I found out
the coil fires better with fourteen gage wire from the ignition
to the coil and another thing if the ohms are incorrect it won't fire in the case
of mine it will only fire on a 3 ohm coil and nothing else

 

Something is very wrong.... What [Exact] components???? Chiwanese maybe?? The size of the wire has very little to do with it... Big enough is... well big enough... More ain't any better...

 

you missed the part about he was hungry and they had hot dogs so they fit across the frame top and it seemed like a good idea at the time

 

My 440cc swm gran milano motorcycle crank but not starting. I checked ignition coil, resistance is 1ohm. If I disconnect the coil, i measured voltage 10V, if I connected the coil, voltage is 0V. What could be the problem, I suspected ECU. I already checked all plugin wiring connections. Battery is new. Kill switch is ok. Fuel pump, horn, lights are running. Please advise.
