Ill cut to the chase with this as i have racked my brains for a while trying to sort this out.I have got low ohms reading on both spark plug coils 1.25,which tells me they are good.I have tested the power pack and have no power when cranking it up on cylinders 1 and 2. I have tryed again with the yellow and black kill switch wire off and still the same. I have checked all earth connections on motor and and my battery connections are all good to?? I really hope i dont have to go under the flywheel to do more electrical tests,but will have to see what responses i get from you lovely people.Im thinking it needs a new powerpack,but dont wanna buy if it could be something else ay! Can anybody help me on this issue as its doing me head right in now.cheers richie
