96 Ranger 3.0L manual Tranny

I changed the clutch master cylinder and the cruise control has stoped working. I think I have plugged back in all the wires.

Tried running the diagnostic listed on another thread but the cruise indicator light never flashes.

Any ideas where to look next?

Thanks,

Mike

 

Maybe this will help..

DIAGNOSIS AND TESTING

--------------------------------------------------------------------------------

Pinpoint Tests

PINPOINT TEST A: SPEED CONTROL INOPERATIVE

A1 VERIFY THERE IS POWER TO SPEED CONTROL SERVO

Disconnect harness connector from the speed control servo.
Use Rotunda Digital Volt-Ohmmeter 014-00407 or equivalent to make the specified measurements at the harness connector. To avoid terminal damage, use Rotunda Terminal Adapter Kit 105-00025 or equivalent.
With the ignition switch in RUN, measure voltage between Pin 7 (Circuit 1003) and Pin 10 (Circuit 676).
Is there battery voltage (12v nom.)?




Yes No
GO to A2 . GO to B1 .

A2 CHECK FOR STUCK STOPLIGHT SWITCH
With no brakes applied, measure the voltage between Pin 4 (Circuit 306) and Pin 10 (Circuit 676).
Is the battery voltage (12v nom.)?
Yes No
Stoplight switch is stuck on. REPLACE stoplight switch. Stoplight switch is OK. GO to A3 .

A3 CHECK BRAKE/CLUTCH CIRCUIT
With the ignition switch in OFF position, measure the resistance between Pin 4 (Circuit 306) and Pin 10 (Circuit 676).
Is resistance less than 20 ohms?
Yes No
Brake input Circuit OK. GO to A4 . Brake light bulbs blown or brake circuit open. SERVICE circuit including clutch pedal position switch.

A4 CHECK DEACTIVATOR SWITCH CIRCUIT
Turn the ignition switch to RUN position.
With no brakes applied, place a 12-volt circuit test light between Pin 9, Circuit 307 (BK/Y) and Pin 10, (GND, Circuit 676 PK/O).
Is the light illuminated?
Yes No
GO to A7 . GO to A5 .

A5 VERIFY POWER AT DEACTIVATOR SWITCH HARNESS CONNECTOR
Remove wiring harness connector from deactivator switch.
Place 12-volt circuit test light between Circuit 1003 (GY/Y) of deactivator switch connector and chassis ground.
Is the light illuminated?
Yes No
GO to A6 . SERVICE blown fuse 11 or open Circuit 1003 (GY/Y).

A6 CHECK FOR OPEN CIRCUIT BETWEEN DEACTIVATOR SWITCH AND SPEED CONTROL SERVO
Measure resistance of Circuit 307 (BK/Y) from deactivator switch connector to Pin 9 of speed control servo connector.
Is resistance less than 1 ohm?
Yes No
REPLACE deactivator switch. SERVICE open Circuit 307 (BK/Y) in harness.

 

Thanks very much! I'm out of town right now but I'll followup in a day or two.

My Cruise control stopped working Wednesdayand I have no clue why. I have a 2000 Excursion. Never have had any problem with the cruise. Is there a book or publication that has the same type of information you just gave the guy with the '96 ranger? I have a CD called the "2000 workshop information Truck" and I have dnoe some research but haven't found anything like you quoted...

 

Look under "V", vehicle speed control, I have the same 2000 disk.
