SOURCE: battery not holding charge.

try testing the battery terminals with a tester check the voltage with the DC 50V range(red to the positive black to the negative body ground). at engine shut the bat should read 12V. start the engine it should read 13 to 13.5v. If it checks that way it should be charging. Same happened to my civic. until I added a grounding lead wire to the negative post of the battery to a good grounding spot to the car engine. It solved my problem. Somehow honda's this series has no good grounding or the original wires are short of conductance.

SOURCE: Car won't stay running.

alternator does not hold a charge it simply charges the battery by unhooking the battery you are taking all voltage from computer and car will not run the proper way to test your alternator is use a multimeter and check voltage at battery while car is running if you have 13-14 volts it should be fine.

SOURCE: 98 cadillac deville battery wont hold a charge

sounds like a 12V drain on the system, like a trunk or glove box light that won't shut off.> Could be many. many other reasons why. The way I would find the draining circuit would be to remove the neg cable of the battery. I then would connect a 12V test light between the neg battery TERMINAL and the neg battery CABLE. With a 12V drain the light will shine. I would install into the light a 9V battery powered recepticle to hold computer and radio station memory. Then I remove fuses 1 at a time, then reinstall, at the same time looking for the 12V light to go out. Hope this helps.

sounds like you have a bad wire or short in the wire that runs from your battery to your alternator. you should have a connector on it which is plugging into the voltage regulator. I had the same thing happen with my 86 Camaro a few years ago

I have an 88 jeep comanche that has a new battery and new alternator but wont keep charge. What could be the problem and how do I fix this.


IF YOU CHECK FUSE.BATTERY CABLES COULD BE FAULTY IF VERY OLD.THEY CAUSE HIGH RESISTANCE IN CHARGING CIRCUIT.CHECK FOR LOOSE DRIVE BELT.AND CHECK ALTERNATOR WIRING IF BROKEN OR DAMAGE YOU WONT GET CHARGED.AND MOST OF ALL MAKE SURE YOU BOUGHT THE RIGHT AMP ALTERNATOR.

Two new batteries, won't hold charge


I would Check the Belt Tensioner. If the Belt Tensioner is Not Holding the Belt Tight Enough it will not allow the Alternator to Charge the Battery and will result in the Dead Batteries. Please Rate My Response! Thanks!

It goes thru the dash circuits. Yes! add a wire from the alternator output to the plus battery . The charge lite may be inoperative - either on or off. You might want to put a fuse in that new line.
A cheap volt-ohm-meter would help you see if the alternator is charging 14-14.8 volt and the alterantor field is being energized.
