No-- it appears that something is NOT turning off or
going to sleep

Google or You Tube Video how to do a Parasitic
Current Drain Test

Remember once you close all doors, they stay closed
or your starting over

It may take a half hour before modules time out

Best you have a wiring diagram & an amp clamp or
volt meter, to put into one of the battery cables, to watch
for the drain (MilliAmps) as you remove the fuses to isolate the circuit with the problem

The alternator diodes were checked out with a scope
or checked for leakage?

Testimonial: "Found the problem, It is in the electric seats. Pulled fuse, truck sat all night and started this morning. Don't think it is the motor, they work fine and stay in position after setting for extended periods. Thinking maybe a bare wire maybe under carpet or the panel under the door that you step on when you get in . Thanks for everyone's help."

    Seat Module is not timing out Look at a wiring diagram & do your testing using it

  • Anonymous Nov 21, 2014

    If the seat moves when you insert the key then maybe a wire issue

SOURCE: car won't start, battery fine, just hear clicks

Even though the lights work, the battery may still be just short on power to turn the motor over thus the clicking. Try charging the battery or jumping, if you still get a clicking it would be the starter solenoid. Considering the year you may just want to replace the whole starter.

does the vehicle have an anti theft device on it if so it may need to be reset. usually all you have to do is unlpug the negative batt cable. for about 5 mins.and reconnect it. if this does not solve the problem look i the owners manual to see how to override the system.

SOURCE: Something is draining my battery on my 1998 Cadillac DeVille

I suspect parasitic draw. All vehicles draw some power from the batteries when the car is shut off. Certain accessories such as clocks, radios remote door openers and alarms always need power. The normal power used is called parasitic draw.

It is always a very low draw so it doesn't run the battery down. If you install accessories like shortwave radios or plug things like inverters and portable refrigerators into the accessory socket and operate them too long without the engine running you can drain your batteries to the point where the engine won't start. If there is an electrical short in the vehicle or a malfunctioning accessory it could be drawing much more than its normal load causing a drain on the batteries. If you leave your door open and the inside lights stay on all night you could drain the battery down till the car won't start.

Here's also a good resource for your car specifically on narrowing down the cause of the drain.

2000 Jaguar SType New battery is completely dead after three days, starter and alternator are both good, and we have disconnected radio believing it might be a drain, what about fuses?


Hello
We had a similar situation and we found out that the battery was the cause , even though it was new.

Try with another battery that you know is good from another car, if still having a problem , check the starter for drainage

New alternator,battery, starter but battery dies overnight and hard too boost shop tested battery and alternator both check good???


If a good battery is losing charge overnight then it is probably being drained by something left on! The usual areas to look at would be the boot light or glovebox light, check these or anything that might be staying on when the ignition is turned off!

Car will not hold charge


I will try and answer this. Most responses you will receive will have you looking for a drain in the system. Very well could be that.

But you said when Jumper cables are removed it does not charge. I have not heard of this in your Year of car, but witnessed it myself in a 2004 F150. There is a circuit called a "battery saver". Its job is to disconnect a battery drain to preserve the battery. What can happen is the Alternator uses power to make and generate even more power.

When a battery is not fully charged it needs a higher rate of charge and the Alternator may be viewed as a parasitic drain. The battery saver activates and disconnects the charging circuit. It can cut off at even 70MPH. I have seen F150's charge for about 5 minutes after removing a jumper and then cuts the battery charging circuit.

You need to be sure the battery is 100% charged. You need the car checked for things like the Diodes and starter draw. If you take the Alternator or Starter for a bench check it will not show how the wiring is working in the car. It is best to check the whole car.

New battery drains.


I can't imagine how changing the belt would have any effect on the electrical system if the alternator is working.
The way you check for a drain is to disconnect the battery ground cable and use a test light to make the connection between the battery and ground. If there is something drawing power from the battery the light will glow.
Then you pull each fuse from the fuse boxes until the light goes out. You also disconnect the starter and alternator if necessary.

Have a 2001 F350 7.3 - 3 weeks ago drove it and let set for an hour came out and was completely dead - no radio, lights, nothing. Tried jump starting ended up putting in 2 new batteries. Did the same...


Have the charging system checked. Autozone, Advance, and Oreilys will do it free. Check Diodes.

Some production years had a weird problem. Its worthy of mention but since you replaced the batteries, it should not apply. Watch your Charge, Voltmeter as sometimes the Alternator will disconnect automatically WHILE DRIVING at even 70mph. The system monitors your vehicle for PARASITIC drains and automatically disconnects the power connection as part of a Battery Saver.

So if Battery levels fall, causing the Alternator to work too hard to recharge a drained system, it will disconnect the charging circuit. Even if if you used a boost to jump the truck, it will charge for maybe 5 minutes and then disconnect.

Now for the battery to drain in 1 hour, you should have a glowing part. About the only thing which could drain that much power is a Rear window defroster or a stuck timer or power relay on the glowplug system.

The glowplugs could be remaining energized and you would not know it. A grounding starter could drain the system. Have a draw test performed.

Most anything else would break a fuse or burn a wiring connection.

Clean the Negative battery cable and if mounted to the block, check the engine to frame strap.

Please rate my info.

Car wont start. its not the battery because its new.


Well even a new battery can be drained down is you have something on all the time, in about an hour.

So start with checking for a drain.
Remove the battery cables in order to clean and grease them.
Then only put one on.
With everything off if you jump the gap of the cable that is off to the battery, with a test light, is should not light up. If it does, then you have a constant drain that will kill a batter over night.
You have to check for things like interior light, and disconnect everything, one at a time, to pin it down.

If you don't have a drain, then the next thing is to check continuity.
When you turn the ignition on, first the dash indicators come on.
The battery should read 12.5 volts.
Then you try to crank it.
The voltage should drop to 10 while cranking, and come back up after.
If it does not drop to 10, the starter is blocked and not drawing.
It could be the neutral safety switch, so try in neutral instead of park.
It could also be the ignition switch.
Use a test light to see of the small wire plugged into the starter solenoid (the small cylinder on top of the starter), get power when keyed to starter?
If it does not, then ignition switch or neutral safety switch.
If yes, then starter solenoid is probably bad.
But try turning the engine over at the alternator by hand or wrench, and try again. Could be binding between starter and drive plate.

Once you get it started, then rev the engine up and verify alternator goes over 14 volts, to recharge battery.
Otherwise battery will go dead in a day.

The battery keeps dying.. I got a new Starter Alternator Fuel Pump and new battery.. But it keeps dying.. Wires are good to..


Something in the system is draining the battery even when the car is off. Have an auto electric shop determine how many amps is being drawn when the ignition is off and the key is out.

Anything above .2A is unacceptable. The auto electric shop should be able to find the source of the draw within a few hours of labor.

Good luck.

New battery, new alternator, new starter. Battery


Something is draining the battery most likly a short somewhere in the electrical system. You will need to have it looked at by the garage to find the short A temporary or cheaper solution may be to disconnect the battery when not using the car. You can either fit a switch inside the car or physically disconnect it at the battery.
