Overcrank Lamp
Engine starts and runs, but overcrank lamp flashes.
Note: The overcrank lamp will flash if speed sensor
signal is absent longer than one second.
Excessive speed sensor air gap?
Open speed sensor circuit? Check continuity of wire 2
(black), wire 16 (white), and wire 24 (red) between P1
connector and speed sensor. Check for 10-12 volts DC
across speed sensor (+) positive terminal and (--)
negative terminals. Check wire 16 for 3--6 volts DC,
and wire 24 for 8--10 volts DC while unit is
cranking/running. Does test check out okay?
Repair circuit.
