that system uses a resistor wire from key 'run' to coil, and when starter is activated with solenoid, there is a straight non resisstive wire to the coil. if sparks are weak, it may make sparks without the resistor in line.. but once you let up.. sparks my drop off. could even be an 'open' in the resistor wire. if it will start but not stay started.
lastly.. if sparks are good, and it runs but soon stalls.. check fuel flow.
Re: ? Solenoid in reply to soundguy, 04-16-2013 10:01:55
I was able to do some work on the tractor and did the following: 1. Replaced the Solenoid, 2. Replaced the plugs, 3. Double checked all wires and replaced several. When I turn the key in the crank position I get nothing (no click and it doesn"t even turn over). Plus I still got a small amount of smoke from the solenoid.
Do you think we are looking at the starter or coil? Or something else? Thanks
