4. Use a known, good, fully-charged battery and
jumper cables to test starter motor. Be sure
transmission is in neutral and PTO is OFF.
Remove heavy lead from post terminal on starter.
Connect one end of positive jumper cable to post
terminal and connect other end to positive terminal
of battery.
Connect one end of negative jumper cable to
negative terminal of battery. Touch other end of
negative jumper cable to a bare surface on
crankcase or to starter housing.
Condition
Conclusion
Relay engages and starter
begins to crank.
Switch is faulty, or there is
a wiring problem to/from
switch. Check wiring and
test switch circuits with an
ohmmeter.
5. Disconnect leads from starter relay and remove it
from starter for testing.
a. Set an ohmmeter on Rx1 scale and zero meter.
Connect one ohmmeter lead to small spade
terminal on relay. Connect other ohmmeter lead
to relay mounting bracket.
Condition
Conclusion
Meter reading less than
3.4 ohms, or an open
circuit is indicated (in
fi
nity
ohms).
Relay is faulty and must
be replaced.
b. With ohmmeter still on Rx1 scale, connect leads
to two large post terminals. Meter should indicate
an open circuit (in
fi
nity ohms, no continuity).
c. Leave ohmmeter leads connected to large
terminals. Connect a jumper lead from positive
terminal of battery to small spade terminal on
relay. Connect another jumper lead from negative
terminal of battery to relay mounting bracket.
Condition
Conclusion
When circuit is completed,
applying 12 volts to
energizing coil, an audible
click should be heard as
relay engages, and
ohmmeter should then
indicate continuity
between large terminals.
Results are other than
indicated, replace relay.
