Topic: 78 cb 750 k7 no spark

[blacksmith1]

my bike s electrics have been modified greatly,received a chopper basic diagram ,have removed a lot of wiring leaving the basics as to the diagram,but no spark,the motor turns but dead ,just wondered ,the original right switch block have left because of throttle gear ,the starter button was not working,put another separate button on, would the kill switch maybe have to be connected ,it seems a dead stop

thanks calj737,the wiring is in a mess,the switch block is totally disconnected,would that have a bearing on the spark,have run the black ignition wire that goes to rectifier have grafted that to the coil and also the points ,thanks for your advice

ahh how good is life ,brother phoned and said try red from the ignition to black and white ,enough spark to kill a herd of rhinos

the block itself is a mess,will look for standard harness and block,its just going to run round the paddock for the time being,have to use the key to stop for the time,thanks for your help mate
