I have a 1995 Jeep wranglar rio grande 4x4 and I have a power drainage which completely drains my battery with in an hour and ive check my alternator by pulling my negative cable and it continued to run. I've noticed while having my headlights on my turn signals does'nt work but when i have my headlights off they work could it be a power shortage with my headlight switch?

You may potentially have an serious electrical drain in your car circuits. The drain is slow and continuous, draining your battery charge even if you do a start. Check the cabling and look for load on your battery with a Volt meter to check for any charge drainage. Check this as a precaution before replacing any more parts.

Have your alternator checked. If you have lost a diode inside of the alternator, it can still charge, but will be a direct short to ground and zap the battery in no time.

battery drain could be ECM, RADIO, DOOR LOCKS,HVAC POWER MODULE.

I'm not sure where the drain hose is but its lower than the floor.
There should be a hose or tube sticking out of the floor or the firewall on the passenger side that drains the ac evaporator.
If the tube is clear, the bottom of the HVAC housing could be blocked.

If you mean it is going dead while sitting you might have a short or another issue drawing power from the battery. take your truck to your local battery warehouse/store the should have a meter thet will tell you if something is drawing on your system. It could be something simple, like maybe the mercury switch on your under hood light is bad and the light is not turning off thus running your battery dead over night.

check the voltage on the battery with a volt meter, it should be around 12.6 to 13 volts, if not charge battery with a charger, after charge try to start vehicle, if the vehicle starts use your volt meter at the battery again, the voltage should be around 14 to 14.5 any lower and the battery isn't being charged and the alternator should be checked and or replaced to solve the problem..

Do you have an alarm? It's common for them to pull too much current and drain the battery. Also look for lights such as dome lights or brake lights stuck on that could drain the battery. Are all the wires to the alternator and battery connected?

when your car does not start it could be a number of things starting with your power system check your battery conections alternator output and battery voltage they should all read 12.6 volts

Hello. If your battery is not charging while driving, often it is due to low or bad voltage from your voltage regulator, which is also in the Alternator usually on these vehicles. Your engine has been running off the battery only and draining it, not using the alternator's power. Here are some things to look for and a question for clarification:

If you actually replaced the alternator already your regulator should be good. But to clarify your problem report, did you replace the alternator or only check it? It may take several checks while truck is running to catch the problem. If you have not done so already you will need to verify that voltage (13.9 volts or more) is actually reaching right to your battery. 12Volts will not be enough, that means something is wrong and is just battery volts. Please do this test while your Jeep is running, with lights on. DC volts across the battery need to be about 14 Volts while all is on. If you don't get that either the Alternator/VR is bad OR bad connection to it.

Unhook pos. cable connect test light from battery to battery cable, if you have drain light will be dim, disconnect fuses or acces. until u find problem
