Ignition Coil Resistance - Cagiva Navigator Workshop Manual

Test the peak voltage of the N° 2 ignition coil primary winding follow-
ing the same procedure used for the N° 1 ignition coil.
N° 2 ignition coil: GR/BK terminal – Earth
Do not disconnect the lead of the ignition coil primary winding.
Circuit tester dial indication: Voltage ( ... )
Ignition coil primary winding peak voltage: More than 280V
If the peak voltage is less than specified, test the ignition coil, the
crankshaft position sensor and the ECM CPU.
IGNITION COIL (check with an electrical circuit tester)
• Remove the ignition coil.
Make sure that the gap of the three spark electrodes of the electrical
circuit tester is 8 mm.
• Using the circuit tester, test the spark performance of the ignition
coil. The connections for the test are as indicated in the figure.
If there are no sparks or the sparks are orange in the above men-
tioned conditions, the ignition coil must be defective.
Spark: More than 8 mm.
To avoid electric shocks, do not touch the pincers during
the test.
Follow the instruction manual when using the electrical cir-
cuit tester.

IGNITION COIL RESISTANCE

• It is possible to use an ampmeter instead of the electrical circuit
tester. In both cases, test the continuity of the primary and sec-
ondary winding of the ignition coil. Exact measurement of the re-
sistance is not necessary, but if the windings are in good condi-
tion, the continuity will be indicated by approximate measurements.
