Sounds like plastic clicking when i accelerate in my 2000 ford taurus lx . Also the battery indicator light comes on and at the same time the temperature gauge goes haywire. What could this be???


Looks like you have an wiring issue.
Battery light comes on and stays on, indicate your alternator is not charging the battery.
But the light goes out and temp. light come on.
And im assuming the its not over heating.
you need to see an auto electrican to diagnose the wiring issue

Battery light is on when idleing, but when i accelerate battery light goes out


Two things can make the bat light come on at idle but go off above idle.
The belt could be slipping because it is not tight, or glazed, or the alternator could be defective.
Once the engine starts, the alternator should be making enough current to "turn the light off". The light is grounded thru the alternator until it is charging, which reverses that circuit and kills the ground source for the light.
If you are sure the belt is ok, I would have the alternator bench tested, because usually if the belt is slipping it slips more at higher speeds.

Changed alternator, new battery, and now no dash lights window power and unless i hold in accelerator the car will die.


test the alternator it may be bad. but it could be something simple as a wire did not get hooked back up correctly. and then there is the other option you didn't disconnect the battery before working on the electrical system and shorted something out. check your ground wires and the plugs for the alternator and anything else you worked on. my neighbor worked on his Honda and it had three bad alternators and he had to go with the orginal expensive alternator to make it run again.

Auto Zone does not test the alternator under full load so the test result could be borderline.
start the car and turn everything on. If the voltage drops lower than 14.2
replace the alternator.
also the battery could be being drained overnight. to check use a test light by removing a battery terminal and connecting light between battery and cable with car off.
if it lights start be removing fuses.
when the light goes off the problem is with this circuit.
lastly if the light stays on take the wires off the alternator.
if the light goes out replace alternator.

Why does my battery keep going dead I have relaced it 3 times a new alternator if the car sits for 2 days or more and is not started and ran the battery is completely dead


BATTERY DRAINS ARE TRICKY. TURN OFF ALL SWITCHES, CLOSE GLOVE BOX. MAKE SURE GLOVE BOX LIGHT IS OUT. OPEN THE HOOD. DISABLE THE UNDER HOOD LIGHT. CLOSE ALL THE DOORS. MAKE SURE ALL COURTESY LIGHTS ARE OUT. DISCONNECT NEG. BATTERY CABLE. USE 12 VOLT TEST LIGHT, CONNECT ONE END TO A METAL PIECE ON THE MOTOR FOR GROUND. FASTEN THE OTHER END TO THE NEGATIVE BATTERY POST. IF THE LIGHT IS ON, THAT MEANS THERE IS A BATTERY DRAIN. LIGHT NOT ON, NO DRAIN. IF THE LIGHT IS ON, FIND THE POWER BOX NEAR THE BATTERY. PULL OUT ONE FUSE, IF THE LIGHT STAYS ON PUT HE FUSE BACK, PULL OUT THE NEXT FUSE. IF THE LIGHT STAYS ON PUT THE FUSE BACK . REPEAT THIS UNTIL THE LIGHT GOES OUT, OR GETS VERY DIM. OUT IS BETTER. WHEN THE LIGHT GOES OUT, THAT IS THE CIRCUIT THAT IS DRAINING THE BATTERY. REFER TO OWNERS MANUAL TO IDENTIFY THE CIRCUIT. IF THE LIGHT NEVER GOES OUT, REMOVE THE WIRES FROM THE ALTERNATOR. IF THE LIGHT GOES OUT, ALTERNATOR NEEDS REPLACING.

My battery light flickers when I am at a stop sign--it goes off when i accelerate. i bought a battery and the alternator tests ok.


either the belt is slipping or the alternator is losing juice at a lower rpm....i take it it was checked in park,or taken out and tested by a machine which spins fast?
