    how does water get into a connector? can i fix that? everyone seems to think its my alternator, but like i said, i got all the battery/load tests done on it, and they all came up good...i've had the dome light issue in my car for years now, sometimes it comes on and stays on for hours, sometimes not....recently, the battery light comes on, but goes off eventually. the door opened light does come on, im thinking that has to deal with the motor with the door locking system?.....i just dont want my car dying you think its more of an electrical problem? my car starts, runs fine...its just the lights that come on all the time...

Try disconnecting the negative battery cable for a minute or two. Then re-connect cable and start the car. Good luck.

I would check the circuits at the key switch first. The anti-theft should only affect the starter and engine, not things like power windows.

Have a load test done on the battery for a failing cell. Check the condition and tension of the drive belt.. Head lights suggest a failing battery.

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.

I just got a brand new battery for my 96 mercury sable and the battery light is on and my radio wont work

usually if a battery light is on it is a sign that the alternator has went out, start it and take the negative battery cable off while its running, if it dies the alternator is bad.. as far as the radio, that has nothing to do with it, most likely a fuse blown.

Why did the battery light stay on after installing a new alternator on my 1999 mercury sable. I put a new belt and tensioner pulley as well as a new idler and power steering pulley. I believe the battery...

check for 12 volts at battery with engine off.

The check for 14 volts with the engine running. If not 14, alternator is not generating any amperage.
