Have you put a meter on the back of the alternator to see if it is putting out voltage but not making it to the battery ?
SOURCE: battery will not stay charged
Check the battery strength and then double check your alternator to make sure it's charging.. I installed 3 alternators, new off the shelf, on one vehicle, and all three were duds (4th one worked fine). If the battery does not need replacing, and the alternator is charging, double check and make sure no components are left on such as a light in the glove box.
SOURCE: charging system
If you have changed the alternator and regulator, about all that could be left would either be a short circuit that is draining current away, or a bad ignition warning light bulb. That is because the power to energize the field of the alternator, comes through this dash bulb.
SOURCE: my 1984 ford f150 is not charging the wire from
If your still having this problem after replacing all of that you either have a short on that wire or on the starter after the solenoid. I would check the starter.
SOURCE: alternator charges at 14.4volts, replaced regulator, same result. boils battery.
The max charge voltage is usually around 14.5 volts, so 14.4 is not high.
Its possible the battery has a dead cell and that is causing the acid problem.
You might want to check with the dealer on what the max voltage is for your car.
