Does your battery warning light go out after reving over 2000rpm?

If not there is a fuse that can cause this if the fuse has blown.

which is the battery warning light ? and which fuse would feed it ?

[gadgit]

He means the charging light on the dash. This light (red) will be on, when you start the engine and only go out when you rev up. I'm sure you would have noticed this as it would be glowing in your face. Also check the volt meter to see if there is a charge going into the system. It should go out at 2200 rpm. we are also assuming you have a 2.9 engine.I can't see in the book which fuse controls this lot but check all the fuses on the panel under the passenger footwell anyway. they will all have a value on them and you should keep some spares just in case. Also check your earth lead from the battery to the chassis and clean everything that looks corroded.Check the second row from the left, second one down, 30 amp as this controls the warning lights, instruments, and indicators. Its not 30 amps for nothing. If all else fails, there are auto/elecs that are mobile for peolpe just like you!

good luck.

did it start when you first put the new battery on?

[mags01]

yes,the week after,but it went straight back to the garage and they checked it and said it was all right

[Paul V]

What does your voltmeter read with/without the car running?
Check the battery light comes on when you turn the ignition on, for some reason if its blown or not connected it can cause the alternator to not charge.

[mags01]

the voltometer reads 11 when the engine is idle and up to 15 running but dips if i put the heater/fan on and the battery light comes on when i turn my key

[Dave_H]

Gadget’s right - I did mean the charging light

If your battery is discharging and it's not obvious what's draining the power, the best way to put a voltmeter across the battery terminals and take the reading - This is without the engine running.

With the meter still there, pull each fuse out one by one, and after pulling each fuse check the meter reading. If the reading goes up after pulling the fuse then it's on that circuit that the problem resides. You'd then have to refer to the wiring diagram to diagnose further.

It is worth looking at the fundimental things first before going down this route, like is the interior light left stuck on etc. Sorry if this sounds a bit obvious.

Cheers,

Dave.
