Checking the magneto supply coil:
Checking the pick-up coil:
Checking the secondary high ten-
sion coil (without spark plug cap):
- Checking the spark plug cap: dis-
connect the spark plug cap from the
secondary cable and measure the
resistance reading between the
ends of the connector: the reading
should be equal to:
5.0 kΩ±15%
- In ignition systems with the HALL
sensor, use the following procedure
to carry out this check (please refer
to the diagram below):
- Using the machine’s own battery
and a few ends of electric cable,
connect the terminals of the battery
direct to the following magneto
cables:
- Connect a tester, selecting the
appropriate scale for continuity /
ohms (Ω), and connecting the pro-
bes as in the table below:
