All, Iv got a 3203 tractor that is acting up. Its giving all the symptoms of a bad seat switch however it was replaced and also jumpered but the tractor still sometimes dies when put in gear and some times when riding it. Its very intermittently. Anybody have a wiring diagram or suggestions?
Welcome to the Forum Levi !
Could be the neutral safety switch in the gear shift lever.
How do i test this if its intermittent?
To check for an intermittent... wire a very small fuse (like 0.1 amp or less) accross the switch or suspected connection. If the switch/connection opens while in use, the fuse will blow. That captures the switch opening. Of course if you get off the seat (for example) while mowing, the fuse will blow.
All, i have replaced neutral safty switch, seat switch, A1 diode, and seat timer. What else sould it be.
Maybe if we can get some more info it will help sort this out. Does it always start right back up? Does it do it when you hit a bump. Hot machine, cold machine, wet, doesn't matter? You mentioned sometimes when you put it in gear. Is the gear shift linkage rubbing or pulling on any wires? Have you tried testing the fuel solenoid? Maybe it gets hot and shuts the fuel off. Could be a break in a wire or more likely connector that perhaps gets warm and opens for a few seconds. If so it will usually completely fail sooner or later. Edit: Just took a quick look and seen tech service manuals on disc for your tractor on e-bay for $45.00 buy it now price. Also seen some $85.00 ones that look identical so look around.
It will typically die first thing in the morning but bot so much in the afternoon. Most of the time it dies when it engauged to gear. But sometimes dies randomly about 30 min later. And yes it starts right back up but will die when shifted into gear again. Where is the ground screw on this machine? Thats the only thing i havet checked that is in the same circuit.
I think I figured it out, it could be the tca15625 module. Imnot sure what it does but if i disconnect it an put it into gear it dies but will start up when in neutral. What is this module called? It not on any of the parts diagrams.
