STARTER SYSTEM
700/800 Starter Lockout Overview and Diagnostic
The Sportsman 700/800 and International EFI starter lockout is controlled by the ECU. Pin #20 senses the transmission signal and
determines if the switch is in Neutral or Park. Pin #24 senses when the brake is applied. When the conditions are met, the ECU will
activate Pin #16 to ground the starter solenoid. Note the ground for the transmission switch runs to the wire harness splice. The ECU
will allow starting in Neutral or Park without the brake applied. Applying the brake overrides this system and allows starting
regardless of transmission shift position.
Items to check when diagnosing a no-start condition are:
• Transmission switch for proper function
• Starter solenoid for proper function
• Brake switch for proper function
• Wire harness, loose connections/pins (including the ECU) leading to and from these components
• Proper ground to frame
Should all these items be found in working order, the ECU may be at fault.
