ELECTRICAL SYSTEM
The electrical system on the gasoline vehicle is 12 volts DC with negative (–) ground to frame, and consists of the
following circuits that are easily identified:
• Starter Circuit
• Generator Circuit
• Electronic Fuel Injection Circuit
• Engine Ignition Circuit
• Engine Kill Circuit
• Reverse Buzzer Circuit
• Low Oil Warning Light Circuit
• Neutral Lockout Circuit
• Fuel Pump Circuit
• Fuel Gauge and Sending Unit Circuit
• Hour Meter Circuit
• Lighting Circuit
Recognizing and understanding the function of each of these circuits will help to quickly isolate the source of an
electrical problem. Use the appropriate test procedure to correct the electrical problem. See Test Procedures.
For a complete wiring diagram, see the Wiring Diagrams for Pedal-Start or Key-Start vehicles.
