Question about 2000 Ford Contour

1 Answer

Pulsing lights, interior, dash, headlights....

Car is a 2000 Ford Contour SE with 2.5L V6

My alternator is good, battery is good, voltages check out with car off, idle, and when driving. The thing is, my lights pulse, not all the time, but only when I am on the gas. I've even gone so far as to replace the cable terminals in case somehow they were corrupted. I know the alternator is fine, it is rated at 130 amps, and a clamp ammeter checks that out, and the voltage goes up to around 14.5 or so when the alternator kicks in, and stays very consistent. I have no idea what the problem could be, and I've seen a few posts about similar issues, but no solutions. HELP!

It is extremely annoying and distracting, and would like to get it fixed before I hand this car over to my younger brother.

If you have a aftermarket radio system I would double check that first,
If not I would check the wire harnesses in the engine compartment,
When you're on the gas the engine tweaks and puts stress on some of the harnesses, if there is a short in the wire harness it will drop the voltage, this will confuse the alternator's voltage regulator and cause it to kick on and off.

My girlfriend has a 2000 Ford Contour SE 2.5 v6 it keeps losing power we put a new alternator and battery in started rite up and ran fine for a couple days now today it started happening all over again the...


the alternator is not charging
have it bench tested as well as the regulator
check driver belt condition and tension
Make sure that the pulley is correct for the belt
if it is a "V" belt and not a flat belt the belt should be at the top of the pulley
If the pulley is wider than the belt, it will be running on the bottom of the pulley and slipping

Ford Five Hundred head lights and dash lights are flashing.


I would check battery voltage with a meter when the lights are flashing to check alternator output. Might be a ground problem.

SOUND LIKE ALTERNATOR PROBLEMS CHECK BATTERY CABLES. MAKE SURE THEY ARE CLEAN AND TIGHT.CHECK DRIVE BELT MAKE SURE ITS NOT LOOSE OR DAMAGED.IF ALL LOOKS GOOD CHECK ALTERNATOR VOLTAGE OUT PUT AT BATTERY WITH CAR RUNNING.BATTERY VOLTAGE SHOULD BE 13.5 - 14.5 VOLTS. IF NOT ALTERNATOR IS FAULTY.

Check the alternator is not faulty.
The battery terminal voltage when engine is running should be approx 14.5V with headlights or venilation blower motor running.
The battery light indicator 'on' usually means the alternator is not charging.

All lights blink with any rpm; fine at idle


Make sure your battery connections mainly your ground had a clean ground on the frame and also make sure the + red cable is secured down. Next if you know how to use a meter check that you are getting at least 14 volts dc on the battery when the car is running. This shows the battery is charging. see if the voltage is fluctuation with rpm. You have a regulator on a car that is designed to keep the voltage steady. I suspect since all your lights dim you have a regulator problem. The alternators job is just to supply a charge to the battery and it should not jump around at a steady rpm. you could have another system loading down on the 12 systems. You can try to isolate this by removing certain fuse's (not ecm or starter things you need to run the car but some of the essentials. you can also go to the fuse box and read the voltage getting to the diffrent systems to help track down the bad load. People for get how important the grounds are and tend to overlook them. where ever the ground hooks to the car make sure the paint is clear and you have good metal to metal touching. Loads on a car very from situations and maybe you can help isolate it by turning off your lights and see if it stops or turn of your radio or what not. You can isolate the load pretty easy with a good meter. I like the ones they sell at home depot for aroun 39 bucks that has the clamp on the end so you can check current. you can clamp it around the red battery cable and watch how much amps your drawing and see if it is swinging back and forth. then once again pull fuses and turn on and off the ac or what ever you can to see if you can get it to stop. one you do you found your culprit. remember that the battery is like a big capacitor and it is there to smooth out the voltage that is being supplyied to it best of luck.
