.Hi I am restoring a lister cs startomatic and I am having trouble with the electrical side
When I switch on the decommpessor sollenoid clicks out giving me compression and away it goes but several seconds later the decompressor solenoid kicks in and shuts the whole thind down. Whe I got it  all the wires from the dynamo to the comtrol box had been cut so I had to patch them by colour whitch was quite faded. Could it be as simple as a  crossed wire. Can anybody help?
