O Indicates a circuit open to ground or de–energized – LED OFF
+ Indicates an energized circuit (clutch coil, solenoid, or start input) LED ON.
” ” A Blank indicates a circuit that is not involved with the logic.
To troubleshoot, turn on the key without starting the engine.
Identify the specific function that does not work and work
across the logic chart. Inspect the condition of each input
LED’s to ensure it matches the logic chart.
If the input LED’s are correct, check the output LED. If the
output LED is illuminated but the device is not energized,
measure available voltage at the output device, continuity
of the disconnected device, and potential voltage on the
ground circuit (floating ground). Repairs will vary
depending on your findings.
