GP 800 i.e.
Disconnect the connector and measure the resist-
ance between coil pins. If values are correct, check
wiring continuity.
For the front cylinder coil:
- Sky Blue cable between coil and pin 10 of the
control unit engine-side connector.
- Black-Green cable between coil connector and
injection load remote control base.
For the rear cylinder coil:
- Pink-Black cable between coil and pin 38 of the
control unit engine-side connector.
- Black-Green cable between coil connector and
injection load remote control base.
Restore connections if necessary.
Electric characteristic
High voltage coil primary resistance value
0.7 ÷ 0.9 Ohm
HV coil secondary check
Disconnect the spark plug caps and measure the
resistance between both.
Electric characteristic
Resistance value of high voltage coil secon-
dary with spark plug caps
~ 17000 Ohm
If values are incorrect, disconnect the caps and
measure the resistance directly between the HV
cable terminals.
Electric characteristic
High voltage coil secondary resistance value
~ 7000 Ohm
If values are correct, measure the resistance of one cap.
Electric characteristic
Spark plug cap resistance
~ 5000 Ohm
