Question about 1999 Ford Contour

2 Answers

When accelerating alternator light comes on.

1999 ford contour. new alternator and known good battery. when accelerating the battery light comes on slowly and all lights dem. If I remove the ground cable off the battery the car continues to run but accelerate the engine flutters then dies. Voltages with battery is around 14 volts. Voltages on battery terminal on alt. 14 volts. Reading the voltages while reving the engine bounces up and down and as low as 10 volts.
Is there something between the alt. and battery that could cause this???

Possible loose or worn alternator belt. Check the condition of the belt. If it's worn, replace it. If it's just loose, tighten it up.

Check the engine ground wire (grounds from the engine to the body.) I had this problem on a ford ranger.

Contour's are notorious for check engine lights. Mine has been on for years. The only way really to reset the CEL is to rent or buy a code reader and record the codes that are stored. Information on CEL codes is available on the internet. FYI the most common code for contour's are P0420 and P0421. These won't cause any driveability issues. As for your heater problem, your fan blower relay is toast

Ford Contour possible short


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.

Battery light comes on and getting briter when accelerate


Electrical system diagnostic is in order here but this is probably going to be a failed alternator. output tests will support the suspicion.... This vehicle should put out a min of 13.6 volts and 85 amps of power @ 2000 rpms.Load test battery as well and test sytem with known good charged battery

Start with changing the alternator. If it continues after that try to find a used computer from a wrecking yard. The ECM/computer is very expensive at the dealership and your local autopart store can't order them.

Have you tried changing the battery.as they can cause that to happen if your battery has a dead cell.

1997 ford contour battery light on & off but mostly on


Check alternator/drive belt, & Have battery & charging system (alternator ) checked. Make sure connections at battery are clean & tight too. If you have a multimeter, check voltage before you start & after & see what it reads & let us know.
