Oil Temperature and
Cooling Fan Switches
(400)
NOTE: This model has an oil temperature switch
and a cooling fan switch.
1. Connect the meter leads (selector in the OHMS
position) to the switch contacts.
2. Suspend the switch and a thermometer in a con-
tainer of oil; then heat the oil.
NOTE: Neither the switch nor the thermometer
should be allowed to touch the bottom of the con-
tainer or inaccurate readings will occur. Use wire
holders to suspend switch and thermometer.
733-554C
3. On the oil temperature switch when the oil tem-
perature reaches 160° C (320° F), the meter
should read a closed circuit.
4. On the oil temperature switch, allow the oil to
cool, and when the temperature is at (or just
before) a temperature of 140° C (284° F), the
meter should read an open circuit.
5. On the cooling fan switch when the temperature
reaches 120° C (248° F), the meter should read a
closed circuit.
6. On the cooling fan switch, allow the oil to cool,
and when the temperature is at (or just before) a
temperature of 110° C (230° F), the meter
should read an open circuit.
7. If the readings are not as indicated, the switch
must be replaced.
8. Apply thread tape to the threads of the switch;
then install the switch and tighten securely.
9. Connect the switch leads.
Coolant Temperature
and Cooling Fan
Switches
(500/650 H1/650 V-Twin)
1. Connect the meter leads (selector in the OHMS
position) to the switch contacts.
2. Suspend the switch and a thermometer in a con-
tainer of water; then heat the water.
NOTE: Neither the switch nor the thermometer
should be allowed to touch the bottom of the con-
tainer or inaccurate readings will occur. Use wire
holders to suspend switch and thermometer.
