Print the "starter motor circuit" from the file above. Looking at the diagram from the battery there are 2 circuits required to start. First circuit is 12v purple wire to a relay... always HOT. The other circuit is 12v to a FUSE, then to IGNITION SWITCH, then to tan wire to SWITCHING RELAY, then to ground. Be sure to check the GROUND wires. Also from the ign switch ORANGE wire to SEAT SWITCH, Then Brown wire to NEUTRAL SW, then Purple wire to PTO SW, then LT BLUE wire to SWITCHING RELAY, then DK BLUE wire to START RELAY and then to ground. Check the GROUND connections. ………….. When you turn the key to START both the ORANGE and the TAN wires at the ignition switch should be 12v. It's probably easiest to use a test light.
