- L4200GST w/ LA680 & BX2200D w/ LA211
The fuel shutoff solenoid on my L4200GST has never worked since I bought it (at ~2000+ hours) - It runs like a swiss watch, but I have to pull the kill knob to shut off the machine. I actually never knew that the tractor was supposed to turn off with the key, but once I found out, figured I'd fix it someday. Today is that day (figuratively speaking).
The solenoid plunger is out, so there is no effect. I have to assume that it pulls in when it is activated, but can't figure out how that is supposed to work from an electrical standpoint.
If the key is off, I have to assume that that there is no power at the solenoid, so shouldn't the plunger be out? If the plunger is out when the machine is off, how does it shut down the fuel? OR, does it pull only in when the key is off but the motor is still running?
If I put a voltmeter on the wire coming into the solenoid, what should I be reading for: off, running, running w/ key off.
Thanks much - JayC
