Gt14 wiring

Recommended Posts

I have a GT14 that i’m Trying to re-wire.  The tractor was a complete basket case when I bought it. The wiring was mostly gone, I was told the tractor was running and mowing the grass when the piston cracked. At that point the tractor sat for a while not sure how long.  In my research to start the wiring I found this wiring diagram and service bulletin to use a 8362 switch.  The tractor does not have points l’m assuming this is an electronic ignition.  Will this switch work with this type of ignition system.  The switch I bought 8362 seems to be the same switch that was on the tractor.  I would like to keep this ignition system and not switch to a points type of system at this point.  I’m getting ready to apply power and I just what to make sure I will not let the magic smoke out of any of the expensive ignition parts.

You do not apply power to the ignition. That is what releases the magic smoke. The single ignition wire is grounded by the ignition switch in the OFF position to shut the engine off. Leave that ignition wire disconnected and isolated until you get everything else working. That way there is no chance of a slip or mistake. To stop the engine just ground that ignition wire on the chassis.

Ok so here is the wiring diagram I used.  I don’t fully trust this diagram.  Because the way it shows is that you have to turn the key to the start position and then turn the PTO switch on for the power to get to the start solenoid.  I assume i’m reading that correctly.  And then the fact that the lights will not work once the PTO is engaged.  I ran a wire straight from the key to the solenoid. And the PTO switch only to the PTO8FAF9A83-809B-4FAE-AED3-7D049035E13D.png.264794d05a0d7c40c0fee7489c07b964.png

The PTO switch acts as a safety. PTO on...no start. 

The GT-14 uses a 4 position switch. Off, acc/run, run and start. The wiring diagram is correct.

The diagram is correct. The PTO switch has two active positions, in the "OFF" position the wire from the key switch "S" terminal will be connected to the wire going to the solenoid. When the PTO switch is in the "ON" position the wire from the "L" terminal of the ignition switch (connected at the cigarette lighter) will send power to the electric PTO.

As @oldredrider said, the switch has four position and needs to be moved back one position after starting to allow the PTO to be powered.

Hope this helps.

I see it now I will have to re-wire that switch to match the diagram

By the way, the ignition switch diagram shows #6 GA wire going to the B and S terminals, well that is BS! #6 is the size of your pinkie finger, A #12 GA wire will do the trick.

I think the 6 ga was leftover from earlier models that didn't have solenoids and used the ignition switch itself to power the starter
