ELECTRICAL SYSTEM

The electrical system on the FE400 key-start vehicles is 12 volts DC with negative ground to frame. It consists
of ten circuits that are easily identified:
• Starter Circuit
• Generator Circuit
• Engine Ignition Circuit
• Engine Kill Circuit
• Reverse Buzzer Circuit
• Low Oil Warning Circuit
• Lockout Cam Circuit
• Fuel Gauge and Sending Unit Circuit
• Hour Meter Circuit
• Lighting Circuit
This key-start vehicle uses the ignition key to activate the electrical system and start the engine. It allows the
engine to run at idle or advanced RPM using the accelerator pedal when the Forward/Reverse handle is in
NEUTRAL. See Section 13 – FE400 Engine.
Use the troubleshooting flow charts in the Circuit Testing section to find the proper test procedure to correct
the electrical problem. See Circuit Testing on page 11-13.
