yes the leads are in the correct way the engine runs on one mag , I checked the spark at the high tension leads on the coils , had nice spark on the left none on the right , i bought a new coil and fitted it to the right hand side still no spark , if the magnets didnt have enough magnetic what ever the other side wouldnt work the earth wire isnt connected so its not a faulty switch , I am thinking the only thing it can be is the steel part of the coil should be earthed and for some reason its not im thinking of running an earth from left hand side coil to the right as the left works and thats the problem this should be a temporary repair or at least a test , anybody got any other ideas ?
