You need to determine which circuit is drawing current from the battery by putting an ammeter in line with the battery cable and the positive battery post. Then start pulling fuses until the draw goes away. From there you will be able to isolate the component on that circuit.

When starting sometimes you will get a click.jump start it and it fires.battery has been replaced.


The click is the starter solenoid pulling in, but the battery does not have enough charge to crank the engine. If it is a new battery, that indicates it is not charging properly, or being discharged while the engine is not runnng. So then, if the alternator warning light is OK, and is not lighting up while driving, the voltage regulator on the alternator is faulty. This allows the battery to discharge to ground whil the engine is stopped.

Charging problem


Battery discharge when shut off is due to a connected add on in the truck,( 2way radio, some item plugged into the power plug, ETC). Also a bad battery will lose it's charge when not being charged,( I've seen brand new batteries do this, Have it load tested, Also the alternator can discharge the battery if the diode is defective. Depending on wiring set up the engine can shut off when you disconnect the positive cable.

Gauges not working, transmission too slow, battery discharged


With engine running, put a volt meter accross battery terminals. If it reads LESS than 13 volts, your alternator is bad.

Can the car alarm kill your battery but you can start the car but after you turn it off battey died again


sure, if you let the alarm drain the battery, this can destroy any stock battery.
The car batteries are not like golf carts and are not deep discharge rated. (so can be damaged)
so charge the battery, if it wont hold a charge, it is bad.
if it discharges silently, and darkly parked , that is phantom discharge
if is discharges , driving that is a engine charge system failure.
parked over night discharging is phantom discharging.
if the alarm goes off and stays in alarm , then dont use, it.
if the battery is happy with the alarm defeated then the Alarm is bad.

The battery measure 12.6vdc charged,(rested) "voltmeter"
and running measures, 13.3 to 15vdc at idle.

this one tool can solve this problem

Ac/heater fan slows and headlights dim intermittently on our 2003accord ex 6 cylinder


engine running or not,,??????
bad battery
or dead charging system.
rusty battery terminals.
check battery voltage parked key in pocket, see 12.65vdc.
if lower , on a warm day the battery is discharged
or at 30F it must be.12.58vdc, rested, if not the battery is discharged
or battery is bad.
if discharged , then charge it.
and fix the bad charging system.
ok you jump start car.
and the battery voltage is 13.3 to 15vdc, if not the charge system is failing, or engine RPM below 800.
if running voltage is below 13.3v the charge system is failing running.

Resolving battery dying out and discharge light dosen't come on?


Discharge light will actually only come on when the alternator is not putting out its normal 13.5 - 14.5 volts. Sounds to me your alternator is fine, your battery has some dead cells, and will go dead soon as you shut off your engine. Battery is not accepting the charge the alt. is giving it. New battery is needed.

Won't start


Sound like your engine will not rotate when attempting to start, the battery terminal connections is loose or corroded.
Battery faulty or discharged, if the cable are clean and tight on the battery turn the key to the ON position and switch the headlights or windshield wipers.
If they won't run then the battery is discharged.
Broken, loose or disconnected wires in the starting circuit.
Starter motor pinion jammed in flywheel ring gear.
Starter solenoid faulty, Starter motor faulty, Ignition switch faulty.
Engine seized, try to turn the crankshaft with a large socket and breaker bar on the pulley bolt.

I have a 1994 f-150 pick up got a new battery & when i put the heat on it discharges & now truck won't.


You mean with the engine running? If the engine is running, the heater fan should be getting power from the alternator, not the battery. Does your battery light go off after engine is running? Or does the voltage gauge show normal charging when running?
If you can start the truck, have your charging system checked out. If it won't start now, have the battery charged up and try again. Then have the charging system checked. If it is good, your heater fan may have a short and drawing too much current, But a heater fan will run the battery down pretty quick, if the engine is not running.

Car wont start but the lights, radio and everything battery operated comes on but it just makes a click noise when trying to start engine


If you can hear a click (quite loud) from the engine compartment, but the starter won't crank, this also could be caused by discharged battery. Battery problems - Discharged or dead battery is one of the possible reasons for a car not to start. Very common is the situation when we forget to turn the lights off overnight (the dome light, for example), which causes the battery to drain. In this case when attempting to start a car, all you will probably hear will be a clicking noise - there won't be enough power to turn the starter. Here is the simple way to check if the battery is discharged: Turn the ignition on. With the engine off, turn the windshield wipers on. If they move way too slow, much slower than usual, the battery is probably discharged. Also look at the dashboard lights - if they appear very dim, the battery is probably discharged.
If the battery is relatively new, it can be recharged. All you need to do is to boost your car and let the engine run for a while to charge the battery.

However if your battery is more than three-four years old, you will probably need to buy a new one. Sometimes, an old battery may even die with no apparent reason, even if the day before it was OK.

If the battery is OK, the starter solenoid, starter cables or the starter motor itself could be a problem.

Check it and tell us news.
