    I got a new battery and it is still doing it. I made sure everything was off everynight, but if I dont start it the next morning its dead. When I connect the jumper cables it starts right away, even if i dont start it for a couple days.

New battery - battery is drained in the morning.Replaced voltage regulator. Disconnected aircon. Still drains overnight. Ute will start and run with full battery but it drains overnight.


Easyest thing to do is pull one cable off your battery. Start pulling fuses and each time touch the cable to the battery post. When you find one that reduces the spark drastically that is the circuit to investigate.

I recently bought a 05 Chevy Equinox and I have been having problems with the battery dies overnight or at random times, any suggestions?


If you've checked all your connection, you've tested the alternator loaded and unloaded and you did a load test on the battery and found it all good, then you probably do have a drain. I would put a DVM on the battery and see if it slowly drops in voltage, if it does, start pulling your fuses, 1 by 1 until the drain stops, then you'll know what circuit is draining the battery. I had a drain going on awhile back, before I pulled the fuses out of the 2000 Chevy van, I sat in it, in the dark everything off and doors closed, I found that the glove box door wasn't shutting all the way and the light inside was draining the battery. Good luck

10 amp draw draining battery overnight on 99 tahoe


I have done this before, put about a 10 amp charger on the battery. Pull the courtesy light fuse first. Look at the battery charger, it is probably charging several amps, pull one fuse at a time. When the charging amps drops down you found the fuse the controls the problem. I had a car several years ago that someone pulled the seat belt all the way out, somehow it was pulling a load and draining the battery overnight.

I HAVE A 2001 VW BEETLE.EVERY MORNING I HAVE TO JUMP THE BATTERY OFF.I CHANGED STARTER,ALTERNATOR IS OK.EVERY MORNING IT MAKES A CLICKING SOUND BEFORE JUMP IT OFF.


Have your battery load tested. It sounds like overnight it's slowly losing it's charge. Another possibility is something electrical is "on" or draining battery overnight.

Jeep 2008 don't start after parking overnight


Does it act like a dead battery? An electrical component could have been left on and drained the battery. If the battery is in good condition it should be rechargeable. You didn't mention if it didn'tcrank, cranked slowly, or cranked and just didn't fire.

Battery drains overnight.


Alternator. The regular inside the alternator has an open diode. Disconnect the battery overnight and it will start the next morning. The alternator will need to be replaced to fix the problem.

BATTERY IS DRAINING EVEN WHILE CAR IS NOT IN USE


I stated "such as a light " there are many, many other causes of 12 volt drains such as a seat switch that might hang up and stick. Empty that battery overnight. First install a 9V Battery Radio memory / and clock or you will have to reset both. Disconnect BLACK negative cable of battery. Using a 12V testlight, connect one end to the disconnected cable, and the other to the negative battery terinal. It should light. Remove the 20A BODY and LIGHTER fuse first . This will eliminate the courtesy light circuit . If light goes off the drain is on that circuit. STILL LIT ? drain is on another circuit. Start by eliminating fuses. Hope this helps.
