TEST STARTER MOTOR
TESTING STARTER SOLENOID:
The solenoid is a normally open, electrically activated switch.
With the keyswitch in the “START” position, the switch closes,
allowing battery current to flow to the starter motor and crank
the engine.
1. The solenoid may be tested while mounted on the engine.
2. A jumper test lead is required for this test.
3. Remove positive battery cable from battery. Then remove
battery cable from stud terminal on solenoid.
4. Disconnect yellow wire from tab terminal on solenoid.
5. Keyswitch must be in “OFF” position.
6. Insert red test lead into receptacle in meter.
7. Insert black test lead into receptacle in meter.
8. Rotate meter selector to position.
9. Attach one meter test lead to each stud terminal on the
solenoid (Figure 6-3).
10. Attach one end of jumper lead to positive terminal on bat-
tery.
11. Touch jumper wire to tab terminal on solenoid.
a. An audible “Click” should be heard as the solenoid switch
“closes.”
b. Meter should make a continuous tone (continuity).

BATTERY INFORMATION
A 12 volt battery is used to operate starter motors on Gen-
erac OHVI v-twin engines. For best starter life and performance,
the battery should have a rating of at least 525 cold cranking
amps at 0°F.
WARNING: Wear eye protection when servicing the
battery. Avoid skin contact. If contact does occur,
flush with cold water and consult a physician.
CAUTION: Before servicing battery, disconnect neg-
ative (-) battery cable and then disconnect the
positive (+) battery cable.
WARNING: Batteries produce hydrogen, an explosive
gas. Do not store or charge a battery near an open
flame or devices which utilize a pilot light or can
create a spark.
