Hello,

I have a 2001 Ford Ranger XLT. A few minutes ago I left my fathers house and turned out on the road, then my dash lights started blinking, truck acted like it was going to loose power intermitantly. It was jumping with in and out surges.

After I got home and turned the engine off, there is a not stop clicking under the dash

Now the power locks do not work, it will not crank, headlights or nothing. But there is this continious clicking.

What I found to stop the clicking was to push the brake pedal. So now I have a stick wedged between the brake and the seat so it will not click all night.

I noticed this a few days ago. I got in the truck, turned the ignition to crank and nothing. I heard that clicking under the dash. I think I must have pressed the brake pedal and it cranked.

But tonight I really need some helpful answers.

Thanks in advance to anyone that could give me some info.

Victor

1ST TEST

YOU AND MR. VOLTMETER

TEST BATTERY VOLTAGE AT BATTERY POSTS

YOUR BATTERY OR ALTERNATOR MAY HAVE BOUGHT THE FARM

IF FOR SOME REASON YOU HAVE VOLTAGE, AT LEAST 12.5 (I DOUBT IT, WITH THE BRAKE LIGHTS ON NOW)

CHECK ALL BATTERY CABLE CONNECTIONS/ CLEAN/ TIGHTEN. ALL THE WAY TO THE STARTER. POS AND NEG. SPARE NONE!

SHOULD YOU INSTALL ANOTHER BATTERY OR GET CRANKED UP

AGAIN, AT THE BATTERY TERMINALS, CHECK VOLTAGE. YOUR ALTERNATOR SHOULD GENERATE AT LEAST 13.8 VOLTS, MAYBE MORE, AT THE BATTERY TERMINALS. OR IT IS NOT PUTTING OUT FOR SOME REASON (MIGHT NOT BE THE ALTERNATOR ITSELF!)

I MAINLY DEAL WITH OLD JEEPS AND OLD FORDS, ON SOME NEWER VEHICLES WITH A DEAD BATTERY, THEY SUGGEST INSTALLING A FULLY CHARGED BATTERY. INSTEAD OF "JUMPING IT OFF". WHICH MAKES THE COMPUTERS NOT FUNCTION CORRECTLY, HAYWIRE REACTIONS AND SUCH OCCUR

I HOPE THIS HELPED

LET ME KNOW HOW IT GOES

After I got home and finally had to wedge that stick between the brake and the seat just to stop that clicking. There was no headlights, no door locks, no brake lights, would not crank, just that contious clicking. But again, with the brake pedal mashed in a bit, no clicking.

Thank You for your information! Any help is most appreciated!

ROGER!

I DO NOT KNOW WHAT WAS CLICKING. MOST LIKELY A RELAY

IF "JUICE" WAS LOW, ACTIVATING THE BRAKE LIGHTS/ SYSTEM PROBABLY ROBBED IT OF IT'S SMALL, BUT LIFE SUSTAINING VOLTAGE. WITH IT CLICKING IN THE COCKPIT, I WOULD "GUESS" THE CONNECTIONS ARE GOOD. EITHER A BAD BATTERY OR A BATTERY NOT GETTING CHARGED, IS MY HYPOTHESIS.

IF POSSIBLE, SNATCH IT OUT, CHARGE IT, SEE IF IT HOLDS A CHARGE. STILL, TEST VOLTAGE IF YOU GET IT RUNNING. MANY POPULAR AUTO PARTS STORES WILL TEST FOR FREE. IF YOU CAN GET IT THERE, OR EVEN REMOVING BOTH ALTERNATOR AND BATTERY, AND TAKING THEM THERE.

LET ME KNOW WHAT YOU FIND

Tonight my speedometer stopped working. Along with that I am hearing a clicking sound in the cab, this sound continues even when the vehicle is off. When you open the door and the cab light comes on, the light flickers off and on to the clicking sound. I have tracked down one relay that the clicking can be heard coming from and felt thru. When I took this relay out, the light in my cab went out, but the clicking sound continued from somewhere else in the dash.

TEST F: SPEEDOMETER/ODOMETER INOPERATIVE - WITH 4-WHEEL ANTI-LOCK BRAKES (4WABS)
Turn ignition off. Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Disconnect instrument cluster connector C216. Measure voltage between ground and instrument cluster connector C216 terminal No. 7 (White/Yellow wire). See Fig. 4 . If voltage is more than 10 volts, go to next step. If voltage is less than 10 volts, repair open in White/Yellow wire between instrument cluster connector and fuse No. 25 located in interior fuse panel and retest system.
NOTE:Measurements must be made at speedometer gauge pins inside instrument cluster printed circuit clips.

Measure resistance of printed circuit. See SPEEDOMETER PRINTED CIRCUIT MEASUREMENTS table. If all resistance values are less than one ohm, go to next step. If resistance in any circuit is one ohm or more, replace instrument cluster printed circuit.
Disconnect 4-Wheel Anti-lock Brakes (4WABS) 25-pin connector C154. 4WABS connector C154 is located in left rear corner of engine compartment. Measure resistance of Gray/Black wire between instrument cluster connector C215 terminal No. 1 and 4WABS connector C154 terminal No. 19. See Fig. 2 and Fig. 7 . If resistance is less than 5 ohms, replace speedometer. If resistance is more than 5 ohms, repair open in Gray/Black wire between instrument cluster connector and 4WABS harness connector and retest system.
