Here is schematic
Battery may not be good! Do you have a voltmeter to check it? Engine has a fuel solenoid in the carburetor that will kill engine if it does not have 12 volts.
At battery? Any change when key is turned to start?
It has kill switches at seat, and brake, and pto switch.
the pto switch in the dash to turn the blades on.
OK< let me know.
Switch comes out the top of dash, it prys out from both ends, but did you check the seat switch and harness?
The run circuit is not complete, and the mower thinks there is no one in the seat.
Ok, let me know.
Did you look at the first link I sent on the ignition system? You have seat switch, brake switch, neutral switch and a relay/
The K1 relay may be the problem!
Is seat switch bypassed?
The relay is part of the module.
yes ,ignition module..
What did you replace? Only one I see for LX172 it the key switch module.
Side of engine sounds like voltage regulator!
That has nothing to do with engine safety switches,
Engine has an electric solenoid in the carburetor. It has to have 12 volts and has to stay open. Could it be closing? Do you have t jump start or use charger?
