SOURCE: my john deere la125 seems to be drawing power wile shut down, it take a week for the batter to go dead, i've pulled the batterer and it stays charged up , I've checked the charging unit and i

What you do is power off the machine, and disconnect the negative battery cable. Put a test light or volt meter between the battery negative terminal and the disconnected negative battery cable.

You will likely have a light or voltage reading...Then you start disconnecting things....I suggest the alternator.

When you have the correct component disconnected and the test light or volt meter shows no current.

If this component is the alternator, they have diode sets inside (or somewhere else in the charging circuit) Typically one diode fails and this causes the draw that you describe. The system often still charges, but at a slightly lower capacity with the failed diode.

Asus eee pc 1000ha wont take charge from adapter


try unplugging from the mains, remove the battery, hold the power button down for 30 seconds. plug the mains adapter in and try turning on. if it doesn't work then it's either the power socket or the mainboard.
if it does work, then try it again with the batter in. if it stops working then your battery's shot.

My Sony Walkman NWZ-BI52F .. when i play music it power off and can notopen again ( batter y is full ) and can't read or charged on pc ? plz help me


Depending in its age, the battery might just be shot. It may say full charge cause it takes all it can but it might only be a few min worth. Most Mp3 players can be taken apart and the battery replaced.

Batter was low and it won't come back on


If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% and graduallythe charge reduces until the battery won't charge up at all. OR The batteryshows a 100% charge but when the adapter is disconnected the battery drops offto zero capacity in a very short time. If the battery drops to an unacceptablecharge level then the battery needs to be replaced.

It wont charge consistently. In other words, its plugged in and the batter icon only shows a partial charge.

The truck will kinda turn over than the batter cables get hot & start smoking. Wont start, battery is fully charged also.


the starter motor could be faulty & needs to be replaced, if the battery leads are getting hot the starter motor is drawing too much current.....hope this helps....cheers.

Battery is dead and I want to charge it and take it in for replacement


Boost your car with jumper cables and let the car idle or drive around for about 20 minutes for the alternather charge the batter on its own .if the car shuts off after you started it might be your alternather is no good . the reason why ur alternather might not be working is because the batter all it does is give enough power for the starter to crank the engine as soon as the engine starts running it gets all its juice from the alternather and it charges the batter as well. but some times when the alternather works and the batter is dead meaning all the cells inside the batter are dead it will never take the charge from the alternather. so you would have to change the batter.

if you would like to know how you can you test both parts useing a volt-a-meter... just ask...

p.s. I think its ur batter if you never changed it. so get that changed for the winter so you wont have any more starting problems during cold wheaters
