check for electric short.
if you have factory or after market alarm, that may be the cause.

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: Honda CRV 2002 air conditioning not cold and was just charged,

Did you have compressor checked to make sure it is not the problem? Or did you just charge due to lack of cool air? Some parts stores can check it. Garages too.. If not the prob let me know..

look for a fusible link out. You need to check for output on the alternator that you installed. make sure the batteries are fully charged before that, otherwise its not going to read right. start from the source. also, you can disconnect the batteries from the sys and do a continuity check on the wires in the loom, so you can see if current has a path, or if you have an open circuit. hope this helps

never mind testing if when you start the car you are getting them voltages then fit a new alternator and quick before you burn out the ECU ,the regulator has packed up end of story ,change alternator now ,NEW not a scrappy one from scrapyard,and stop try to confuse the issue with something you do not know ,no voltage leaving the alternator should not exceed 14.7v

Honda CRV 2007. Battery light is on, I checked the battery & conections & the alternator and everything is fine. I used an electrical meter to check it. Could it be a fuse and if so, which one?


Have you checked for codes in your engine control module or other computers within your car ? Alternators have a voltage regulator within in them, which may be going bad and could be your problem.

What have you done in the form of diagnosis about your issue ?

Battery Wont stay charged


Then either you have a trickle of electricity running all the time from something left on. Maybe from amateur wiring like a stereo or fog lights. If not then your battery has come to the end of it's life decomposing the plates inside and developing a high internal resistance making it hard to charge. If so replace the battery and the voltage regulator since you should never replace one without the other.

There is a ground some were that is causeing the battery not to charge put new selinoid ,new battery,alternater,new key lock cylender check wirers fuses relay switches and battery still wont charge


It sounds like you have done a whole lot of replacing and not much "diagnosing". Did you chech for battery voltage at the alternator? There should be battey voltage at the large Black/Orange wire that is on the B+ terminal of the alternator. This wire should have voltage all the time. If there is no battery voltage, you most likely have a burned fusible link at the starter relay area.
There should also be voltage at the "S" terminal with the ignition on. If there is no voltage, then check for voltage at the "S" terminal of the voltage regulator. If there is no voltage at the "S" terminal on the voltage regulator then check the "I" terminal on the regulator for voltage.

NOTE: The voltage on the "S" terminal should be 1/2 that of the voltage on the "I" terminal.

If there is voltage on the "I" terminal, make sure your voltage regulator is grounded properly to the fender and retest to see if it is charging the battery. If it is still not charging, disconnect the regulator connector and connect a jumper between the "A" and "F" terminals of the connector. Start the engine. The alternator should now be charging the battery at high voltage (usually over 15 volts) If it does, replace your voltage regulator. If it does not, then you need to check your wiring between the voltage regulator and the alternator.

My car recently had an issue with charging the battery. We replaced the altenator. That did not fix the problem. Batter was still not getting charged. So we got a new regulator. Still nothing. I...


ALL OF THE FUSES NEED TO BE CHECKED WITH A FUSE TESTER. THERE ARE FUSES UNDER THE HOOD & INSIDE THE VEHICLE. ALSO, WITH THE MOTOR RUNNING AT A HIGH IDLE, PUT A VOLTMETER ON THE BATTERY. IT SHOULD READ BETWEEN 13.80 & 14.90 VOLTS. IF IT READS LOWER THAN 13.0 IT IS NOT CHARGING. IF IT READS TOO LOW MEASURE THE VOLTAGE AT THE ALTERNATOR WITH THE MOTOR RUNNING. IF IT READS TOO HIGH THE ALTERNATOR IS CHARGING BUT THE VOLTAGE IS NOT GETTING TO THE BATTERY. YOU MAY HAVE TO REPLACE THE WIRE BETWEEN THE ALTERNATOR & THE BATTERY.

Yes, I would have the battery fully charged and load tested. Most local parts stores can test it for you. Takes a hour or so.

After charging the air conditioner in my honda crv, the compressor will not work


Did it work while you where charging it up?If there was too much in the system,it is possible the high side switch may not let it come on.Also,if the battery was disconnected on the negative side for 20 seconds it will reset the ac system,but the computer might loose it`s memory on this model unless you have had the battery disconnected before.

My battery and ny alternator are new u think it can be that voltage regulator that is not chargeing my battery


Hi Nanfragoso,
The voltage regulator for your vehicle is built into your alternator. The vehicles on board computer controls the charging system. If it sees too high of a load,it can turn off (or down) the charging system at idle. Be sure to check the output at 1500 rpm.There are 3 fuses listed for the charging circuits. Two are located in the under hood fuse box. #15 and #19 are 60a fuses. One is located in the dash fuse box and is #2- 15a. Give these a quick check. If you don't find a blown fuse,drop me a line and we can go on with the diagnosis. Thanks,Chuck

Honda S2000 engine installed in kit car. How do I wire alternator


Unfortunately the Honda alternator is regulated by the ECU, which allows the ECU to intelligently reduce alternator engine loading to improve fuel consumption. The intelligent system uses an electrical load detector (ELD) located near the battery to control the alternator output voltage. A two wire alternator has an inbuilt regulator that will always generate the required charging voltage. When a battery is fully charged and the electrical loading is low there is no need for generating the charging voltage, in this situation the honda alternator will reduce the output voltage to reduce engine loading, hence improved fuel economy.
