I just replaced the start solenoid which was grounded.Also then discovered that the circuit tied to the thin lightweight ring terminal,has a dead short.This ring terminal is attached to the hot post on the solenoid.Two light wires are crimped on that ring.At least one of those or both are shorted.There is no power thru the start switch to operate the solenoid relay.I can assume that one of the wires mentioned is the feeder to the start switch.However The ring terminal remains disconnected due to short. With ignition switch on, the dash indicator lights function.When that switch is turned to the start mode, indicators go out and there is no power to fire the relay.Can any one identify the wires in question?I have no diagram of system.Is it possible that one wire is from the altenator.If so I must be in trouble because this Lucas alternator is fitted w/four wires plus a ground.Also English electrical symbols seem to differ from American ones.I can jump the to the relay to start engine but if I do so and operate the the tractor is there any problem for the alternator.
