VOLTAGE
(Wiring Harness Side)
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester to the brown/black wire; then
connect the black tester lead to ground.
3. The meter must show battery voltage.
NOTE: If the meter shows no battery voltage, trou-
bleshoot the battery, fuse, switch, or the main wiring
harness.
NOTE: If the meter shows battery voltage, the main
wiring harness is good; proceed to test the
switch/component or connector.
RESISTANCE (Switch)
1. Remove the spade connectors from the brake switch.
2. Set the meter selector to the OHMS position.
3. Connect the red tester lead to one switch terminal;
then connect the black tester lead to the other switch
terminal.

4. When the brake pedal is depressed, the meter must
show less than 1 ohm.
NOTE: If the meter shows more than 1 ohm of resis-
tance, replace the switch.
Oil Temperature and
Cooling Fan Switches
(350)
1. Connect the meter leads (selector in the OHMS posi-
tion) to the switch contacts.
2. Suspend the switch and a thermometer in a container
of cooking 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 tempera-
ture 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 tem-
perature 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 tempera-
ture 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.
Engine Coolant
Temperature (ECT)
Sensor (425)
1. Connect the meter leads (selector in OHMS position)
to the sensor terminals.
2. Suspend the sensor and a thermometer in a container
of cooking oil; then heat the oil.
! WARNING
