Here is the procedure I use to isolate a battery drain. Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or "light" if there is a drain. If the "light or glow" is faint, that is probably normal draw for the clock or computer. If the "light or glow" is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. Remember to hold in the button in the door jam for the interior lights.

2007 rav 4.Battery light came on, drove 20 miles on hwy. stopped, shut car off.started car with a very slow crank. Power steering was gone, all warning lights came on barely made it home. now dead.


Used your battery up just getting home. Now recharge the battery, and test the charging system- could be a bad alternator not charging the battery.

Normally, the alternator powers all the car's electrical needs when the engine is running. If the alternator fails, the battery will then be used to run the electrical needs until the battery is depleted, then the car will shut down. Dead, just like yours. No big deal, just find out why the charging system stopped.

2010 G37 - battery was dead - jumped it off and drove it for twenty minutes. Next morning it wouldn't start and now it wont stop clicking (like a relay). Any suggestions?


if the battery goes dead or low it must be recharged with a charger, driving the car will not recharge it properly. The alternator is only meant to maintain the battery, not recharge it. Get the battery recharged and verified and then try again.

Battery drain


You can check with a 12v test light or an amp meter. If you take off one of the battery terminal ends, (preferably the negative) and run the test light or amp meter in series from the battery post to the cable end, see if it lights up.


If it does, then you will want to start pulling fuses one by one until it goes out. When it goes out, then that is the circuit that is causing the draw. If not, then the battery is bad, as it can't hold a charge.

The recommendation for maximum parasitic drain is around 30 mA (0.030 amp). A typical drain today actually falls into the 7-12 mA range, even though some vehicles do approach the maximum. Multiply the drain (in amps) by the time (in hours) the battery sits without being recharged. The result is the amount of AH consumed by the parasitic drain. The actual drain may be small, but over time the battery grows steadily weaker.

Just remember to keep all of the doors closed when you do this and disconnect the hood light if there is one, thanks

Does not start, battery ok. alternator and starter test out ok


The car battery has 6 cells, each cell holds 2 volts, and connected in series adds to 12 volts. Just like your flashlight, each battery hooked in series results in increased voltage. Its possible one cell is not holding a charge, which slowly drains power from adjacent cells. In battery series connection, if one cell won't hold a charge, electrons will flow to lowest cell voltage in attempt to equalize voltage. So when one cell drops to less than 2 volts, the electrons from other cells will flow to this cell to recharge and bring voltage up to equalize voltage level. To diagnose for dead cell in 6-cell car battery, remove the 6 caps to expose the electrolyte liquid AFTER you have recharged the battery for 20 minutes with 10-amp charger, or until "fully charged" indicator comes "on." With a digital voltage meter set to 5 volts DC reading, connect the negative black probe to negative side of battery and touch the liquid electrolyte with the red positive probe. The voltage meter will display the voltage reading on each cell as you move the red positive probe from one cell to another. Make a note of each voltage reading from each cell. Wait one hour or more, then take another reading of each cell. The cell that has the lowest reading is the one that's draining power from the adjacent cells. A normal battery will show no change in voltage level between the first and second reading an hour later. A defective battery will show a drop in voltage to indicate one or more cell is slowly draining power to gradually render the battery completely dead 36 hours later.

What's your problem?\ battery keeps draining in 2001 chev cavalier


Then its not the battery,The 2001 cavalier is known for its low output and slow parastatic drain which drains in 20 days of no use and result is a dead battery. What you are mainly dealing with is a bad battery cable/terminal or improperly connected. you mainly need a terminal connection.

I try to start it and it just make a click noise and wont start


Possible bad Starter motor. Possible dead battery. Possible bad Alternator resulting in a dead battery.
First try have someone hold the key in Full Start position, hear the click and tap on starter motor with a hammer. If it kicks in and starts up (be ready for that) then the starter is going bad and should be replaced. (Might get 3 -4 more starts like that)
BE VERY CAREFUL TO NOT TAP ON WIRES.
If there is no change, then you should be able to jump start it with cables from another battery/car.
Then you need to figure out if the battery is expired or if the Alternator is not charging enough.
You can do this with a multimeter on the battery. With engine running you should read about 14.5 volts or more, up to around 15 volts plus.. If not, if voltage is around 12 volts or lower, when running, then you will need to replace the Alternator.

If you are getting good voltage from the alternator, then you can assume you need to replace the battery. The other alternative is a short circuit draining the battery or you left a light on somwhere and drained it. Run the car for 30 to 40 mins minimum to recharge battery (idle is good). Or just use a battery charger. 10 amps for 3- 4 hours, or 2 amps overnight..
Hope this is helpful.

Will not start, was running fine no sign of any issue and than stopped parked 15min engine off and than returned with no battery. My keys made a different noise and the car ignition makes a strange...


Have the battery checked out, it can drain within minutes and it really is gone if you have dead cells that can't recharge. It will make your car click when trying to start or it could turn over slow or not make any sound. Good Luck.

Battery light went on and the vehicle died under way 20 minutes later.


If the Power steering and everything else seems to work the problem should be in the Alternator or Battery. Check your Battery cables for loose or dirty connections.

If you find the Battery cables were the problem, you need to recharge the Battery. A jumpstart may get you going, but the Alternator is meant to keep up with the current electrical demands and it will take a long time to fully recharge the Battery.

Autozone and Oreillys can check the Alternator and Battery if they are carried in, or on the car. Since the Expedition is dead, you can take in the Battery for a recharge and testing. This will keep you from needless work removing the Alternator if only the Battery was bad. If the Battery tests good after the recharge, then your only remaining option is to remove the Alternator for testing. Should both the Battery and the Alternator test out good, you have a major electrical malfunction. You will need an electrical shop.

No electrics working


Could be the new battery is dead, from something in the vehicle draining it.charge up the battery and see what happens.Also could be the alternator is not charging the battery while vehicle is running.
