NOTES

1. Consoles without automatic transmission or gauges only have therear console light connections to the under dash harness.

2. 1967 consoles with gauges use 2 leads from PIN 1. One feeds therear console light. The other feeds the clock in the gauge cluster. No"in harness" junction block is used.Consoles without gauges may use a console mounted clock poweredby a lead from PIN 1.

3. Low fuel indicator may not exist in the gauge cluster. If so ignore thislead.

4. For 1967 consoles a 4 PIN connector is used to mate the purple

ignition leads (pINS 3 and 4), the pink power lead (pIN 9) and thelight green backup light lead (pIN 6) to the neutral safety switch.For 1968-1969 consoles a 2 PIN connector is used to mate the purpleignition leads (pINS 3 and 4) to the neutral safety switch. ihe pinkpower lead (pIN 9) and the light green backup light lead (pIN 6) eachhave separate connectors at the neutral safety switch.

5. Manual transmission cars do not use the PIN 3 and 4 purple ignitionleads, the light green backup light lead (PIN 6), or a pink power lead(pIN 9) to the neutral safety switch.

6. Consoles with automatic transmission and gauges may use 2 pinkleads from PIN 9. One would feed power to the neutral safety switch.The other lead splits at an "in harness" junction to feed power to thetemperature gauge and the fuel gauge.

7. Consoles with automatic transmission and no gauges use 2 grayleads from PIN 10. Each routes directly to an automatic shift platelight. No "in harness" junction is used.Consoles with automatic transmission and gauges may use 2 grayleads from PIN 10. One lead splits at an "in harness" junction tofeed the automatic shift plate lights. The other lead splits at an "inharness" junction to feed the gauge cluster lights.

8. A ground wire exists in the harness from the console gauge clusterchassis to a body grou nd. The automatic transmission shift platelights ground via this lead through an "in harness" junction. Gaugecluster lights ground directly to the gauge cluster chassis.

9. All console gauge cases ground to the console gauge cluster chassis.

HEADLAMPDOOR DIAGNOSIS

FUNCTIONAL TEST

The following three steps should be performed duringnew car preparation or before any detailed diagnosis isperformed.

I. Start with ignition switch and head lamp switch both"OFF ."

II. Pull headlamp switch to headlamp position andcheck to see that:

A. Head lamps come on. This circuit is needed to closethe doors.

B. Headlamp doors open -1. If they open, one-half of the control circuit is

okay - go to step III.2. If they don't open, the add-on harness for this

option may not be connected at:a. Double connector under dash.

b. Main light switch (light blue wire).3. If they don't open [and step (2) is okay] turn the

ignition key to "ON" and observe the doors.a. If they open, the one-way diode is shorted or,

b. There may be a short in the brown wire to theignition switch or,

c. The circuit breaker may be defective (possiblycaused by shorted diode or low relay voltage).

III. Start the engine and operate the light switch anumber of times to test the lamp and door opera-tion. This eliminates a possible marginal voltagecondition at the relays if the battery is slightly low.Listen for relay click noise asthe headlamp switch isoperated from on to off. Also listen for circuitbreaker click if the doors fail to function in eitherdirection. A circuit breaker click noise indicates ashort in the system.

DETAILED DIAGNOSIS

If the above mentioned steps do not pinpoint theproblem, continue diagnosis as follows:

If neither door opens; look for a defect in an areacommon to both motors:

A. Check black ground wire from relay R3 to ground atradiator support. This is the motor ground path.

B. Check to see that Relay R1 is energized by unplug-ging the two-wire connector. The relay should clickas connector contact is broken and made. If not, usea test lamp between the two terminals of the two-wire connector. The lamps should light up if wiringis okay and head lamp switch is on. If it does, re-place relay R1.

tI

C. Check to see that relay R3 is not energized byunplugging the two-wire connector. The relayshould not click when COf1nectorcontact is brokenand made. If the relay does click, there is a possibleshort in the brown wire to the ignition switch incombination with a broken wire such as mightoccur in a pinch condition. Check with a test lightbetween ground and each terminal of the two-wireconnector. The test light should light both times.

D. Use a test light and check from ground to the fol-lowing terminals (test light should light up):

.~1

If neither door closes when lights are turned off, checkfor voltage at the green wire terminal on relay R1 (usetest lamp to ground). Note: Ignition switch must be"ON" to energize system and the eng~ne should berunning during checking operation.

A. If there is voltage at green terminal, check for ..vol-tage further along the harness towards the motors. Ifthere is no voltage at the brown wire terminal ofrelay R2, then R2 and R3 (they are wired in parallel)are not actuated. Check for 12 volts' across thetwo-terminal connectors of both relays (useone testlight lead at each terminal of connector).1. If voltage is present, replace R2.2..lf no voltage, check wiring back to the ignition

switch making sure that the diode is not open orin backwards.

B. If voltage is pulsating, due to action of circuitbreaker, then R2 has pulled in but R3 has not. Checkfor 12 volts across the two-terminal connector of R3(one test light lead at each terminal of connector). Ifvoltage is present, replace R3. If no voltage, checkwiring.

C. If there is no voltage at green wire terminal of relayR1 (use test light to ground), check for voltage atorange wire terminal of R1.a. If voltage is present, replace R1.b. If voltage is not present, check for open circuit

breaker or wi ri ng.

If one door does not operate the same as the other,look for a malfunction in that particular door's -motor,switches, or wiring.

Door does not open

A. Check for a mechanical binding. If motor is beingprevented from turning, a flashing blue light in itsterminal housing will indicate that the motor'sthermal overload switch is operating.

B. Check for voltage between limit switch (on radiatorsupport) and motor. Use test light from top limitswitch terminal to ground.1. If no voltage is present:

a. Check connections at top and bottom of limitswitch.

b. Check wiring from relay R1 to bottom of limitswitch using test light at bottom terminal oflimit switch. Test light should light.

c. Replace limit switch if bad.2. H there is voltage present, check for voltage be-

tween motor and limit switch on headlampassembly. If voltage is present:a. Check connections at top and bottom of-limit

switch.

b. Check wiring between bottom of limit switchand ground at relay R3.

c. Replace limit switch on head lamp assembly ifbad.

Door does not close

A. Check for mechanical binding.

B. Check for voltage between limitswitch at head lampassembly and motor:1. If not voltage is present:

a. Check limit switch connections top andbottom.

b. Check wiring from relay R2 to bottom of limitswitch. Use test lamp from terminal to ground.

c. Replace switch if bad.

2. If there is voltage present, check for voltage be-tween motor and limit switch at radiator support.If voltage is present:a. Check limit switch connections - top and

bottom.

b. Check wiring from bottom of limit switch toground at relay R3.

c. Replace limit switch if bad.

Motor does not stop running at end of door travel.

After a few second of stall, the motor's thermal over-load will start flashing in the terminal housing of themotor. Check for sufficient contact between the doormechanism and the appropriate limit switch for proper

TerminalProblem if test lightdoes not light.

switch operation. Push in the switch button to insureoperation; if motor continues to flash (operate) replaceswitch.

Door moves jerkily.A. Check for loose connection in circuit.B. Check for mechanical bind in the door mechanism

(the motor's thermal overload will probably beflashing).

HEADLIGHT DOOR ADJUSTMENT

The headlight door adjustment is proper when:A. There is clearance all the way around the door in

the closed position.B. The limit switch is actuated to shut off the door

motor.

C. The door is flush in the opening.

Adjustment can be made as follows:A. The door cover is retained by 4 screws threaded into

caged nuts. These nuts have up to .090" movementfor door cover adjustment when the screws areloosened. Use this adjustment to square the door inthe opening by measuring cI~arance (.025" -.050") all the way around.

B. Ifthe door assembly is cocked at an angle (down orup) in the opening, shim the assembly at its radiatorsupport moul'1tingscrews.

C. Adjustment of the limit switch, if needed, can beobtained by slotting the mounting bracket holeswith a round file. This should be used only when theother adjustments fail to provide better than margi-nal clearance around the door.
