I was recently loosing spark to one of my cylinders once my bike got up to running temperature. Figuring it was a coil problem I ordered a replacment coil. I have fitted this new coil but it doesnt deliver spark to either of the 2 cylinders it is supposed to. My first guess was that i had been sold a lemon, so, i refitted my old coil to find that it also does not deliver any spark to either cylinder. The fact that neither this "new" coil, nor my old one (which always worked ok when cold) give any spark leads me to think that its not a coil problem but something earlier in the line.
I tested the voltage across the 2 wires that attach to each coil (not the HT leads but the other "skinny" ones) and get a reading of 9volts for both my 'good' and 'bad' coils when i crank the engine. This seems about right to me.
Is there anything else that could cause a problem like this aside from dodgy coils?? I dont want to accuse the guy i brought the new coil from, of selling me a lemon if it is actually something at my end.
Any suggestinos would be greatly appreciated.
Cheers.
