Are you sure that is a red wire and not a red wire with a brown stripe? I believe that is the connector for the brake light switch - if the brake light is not on, the starter solenoid does not have a ground and it wont start - with the brake light on 24/7, it will drag the battery down while running.

The switch is hydraulic and is usually in the junction block where all the brake lines converge. A switch may be available from an auto parts store and the Polaris part number is 4015069 - it is $120 from Polaris

No other test - it's a NO switch until pressure is applied and then it closes to turn on the brake light - it's either off or on

I've got to replace one on a Chinese Yard Sport - wires are connected with screws - $19

The speed sensor can be tested

SPEED SENSOR TESTING
Special Tools Required:
ELECTRICAL
Static Timing Light Harness: 2871745
Hall Sensor Probe Harness: 2460761
1. Disconnect the 3 wire harness from the speed
sensor and remove the sensor from the
transmission.
2. Connect the wires from the Static Timing Light
Harness to the sensor 3 pin connector using the Hall
Sensor Probe Harness (PN 2460761 ).
3. Pass a screwdriver back and forth in front of the
sensor tip.
4. Be sure connections are good and 9V battery is in
good condition. If the light flashes, the sensor is
good.
