Question about 2002 Mercury Sable

1 Answer

Battery light still on, after replacing alternator & battery

I have a 2002 mercury sable with the DOHC 3.0 L. My battery light came on, so I had the system checked out. The diagnostic said the alternator was bad. After replacing the alternator, the battery light was still on. Even after clearing the computer. I had the battery load tested and it tested good. However, I was still skeptical about the battery being ok. I decided to replace the battery and cleared the computer and the battery light is still on.

I'm at a loss, not sure what the problem could be.

Recheck ALL your battery cables,,,(did you disconnect your battery when you replaced the alternator??)..oooppss.. Take your battery to O'Reilly's or Autozone and have them check the CCA (Cold Cranking Amps)..amperage is what makes the car start..not voltage..

Charging system light on 2002 Mercury Sable

If the light is on there is a problem in the charging system, possibly a defective diode inside the alternator rectifier.

All lights flicker a little on my 2002 mercury sable

Check the ground. Or it's the alternator. Best thing to start out with a digital multimeter on the battery voltage while the car is running.

Cps location 2002 mercury sable

The crank sensor on the 2002 DOHC engine is located just under the alternator and you can change it but you have to get at it from underneath the car.

2002 mercury sable DOHC check engine light

A flashing light indicates that the engine is misfiring enough to damage the catalytic converter, this needs attention ASAP, otherwise after the misfiring is repaired, you will be buying a new catalytic converter, the damage may have already been done. as for the p1633 has the battery run low and you had to jump it off, or recharge the battery?
