my 95 discovery battery is aways dead i charge it and a few hours later its dead again. Can anyone tell e what it may be.

 

Have you had the battery tested?

 

If it's dead in a few hours due to a drain the battery to fuse box cable would probably be warm to the touch. If it isn't, then it's likely a bad battery.

 

Get a little tail light. A small bulb.

Pull the negative off of the battery.

wire the bulb in so that one end of the bulb goes to the battery, the other end to the (-) cable.

Take out the keys.
Close all the doors.

The bulb should be OUT and dead.
If it is glowing, there is a drain.

Get a bigger bulb like a brake lamp or tail light and see if that bulb glows.
That one takes more current.

If it glows, then pull out fuses one by one and only one at a time until the bulb goes out.

When the bulb goes out, note the fuse #.
Look it up in the Owner's manual..

Commonly:

1) Your battery has an internal short and is a bad battery
2) Your alternator has a shorted diode and is drawing current. You need to remove the wires of the alternator to test this.

Anyway, this is how to troubleshoot it.
Good luck.
