Brakelight Switch

(Pressure)

The brakelight switch is located on the top of the aux-

iliary brake master cylinder and is pressure activated

by the hand brake or the auxiliary brake pedal. This

switch also activates the start-in-gear (SIG) relay in

the power distribution module (PDM).

NOTE: The ignition switch must be in the ON

position.

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,

troubleshoot 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.

KC274

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

resistance, replace the switch.

Oil Temperature and

Cooling Fan Switches

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 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 temper-

ature 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.

! CAUTION

Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.

! WARNING

Wear insulated gloves and safety glasses. Heated oil
can cause severe burns.
