Minimum brush lenoth:
5.5mm (0.22
in.)
f. Check brush spring pressure. Replace spring if
it
is weak.
B. Starter Relay Switch
1. Inspection
a. Disconnect
starter
relay leads
a t
the relay.
b. Connect pocket tester leads to the relay ter-
minals (ohms x 1 scale).
c. Turn ignition on ("I" position) and engine
stop switch to "RUN".
d. Push starter button. The relay should click
once and the scale should read zero ohms.
If the relay clicks but the scale does not read
zero, the relay must be replaced.
e. I f the relay does not click, check the wires from
the starter button and the battery (red/white,
blue/white). Turn ignition off.
Use (ohms x
1 )
scale on tester. The resistance between these
wires should be no more than
3.5
ohms. If
there is more resistance, the relay should be
replaced.

d. If the indicated voltage cannot be reached,
then perform the tests in step
2.
NOTE:
Never disconnect wires from the
battery while the generator is in operation. If
the battery is disconnected, the voltage across
the generator terminals will increase,damaging
