RESISTANCE MEASUREMENTS
As an alternate method, magneto system compo-
nents can be checked with a digital ohmmeter.
NOTE :
All resistance measurements must
be performed with parts at room tempera-
ture (approx. 20°C (68°F)). Temperature greatly af-
fects resistance measurements.
Disconnect connector at ignition coil and magneto
junction. Measure resistance between each ter-
minal. Refer to the following table for values and
wire colors.
NOTE :
An ignition coil with good resistance
measurement can still be faulty. Voltage leak
can occur at high voltage level which is not detect-
able with an ohmmeter.
➀
: The primary winding of ignition coil can not be measures because there is no external connection.
