Remove the feeler gauge, and then recheck the air gap.
Install the fan cover (P. 7-3).
CHARGE COIL AND DIODE TEST
1. Select the diode function of a digital multimeter.
2. Attach the red lead to the laminate core (ground) and the
black lead to the charge coil terminal.
3. Check for the specified voltage drop.
Specified voltage
4. Reverse the test leads so that the black lead is on the
laminate core and the red lead is on the charge coil
terminal.
The meter should read OL (Over Limit) or
OC (Open Circuit).
Follow the meter manufacturer's instructions for testing
diodes. Some meters show current flow from negative (-)
to positive (+), while others show current flow from
positive (+) to negative (-). The polarity of the meter does
not matter when testing diodes. As long as the meter
shows current flow one way and not the other, the diode
is good.
5. Replace the ignition/charge coil if any of the above tests
are out of specification.
