SPIDER MAX 500
The coil control circuit operation is normal.
Carry out the check of the H.T. coil
secondary circuit, cable and shielded
cap (see p. 92).
Measure the voltage across the testing
wiring PIN 20 and PIN 23 during the fuel
pump cycle.
To start the cycle move the key switch to
the "ON" position and the emergency switch
to "RUN" and lift the side stand.
PIN 20-PIN 23 = Battery voltage (in
combination with the pump rotation - 2 sec.).
In order to increase the testing time, enable
the "pump relay diagnosis" function (30
seconds).
The coil main control circuit operation is normal. Check the central unit and the
coil connectors with care. Replace the central unit if necessary.
Disconnect the connection to H.T. coil main
circuit
Measure the voltage again:
• PIN 1 of the coil connector
• PIN 23 of the central unit
Voltage in combination with the pump
rotation (2 seconds).
