Just tried to pop out and once I turn the engine over the battery light is staying on :-? I had this just before xmas and it faded on and off, I changed alternator and then had no more problems. But this time it stays on all the time, any quick checks I can do in the dark  Need to be out by 8pm but dont fancy the battery draining while Im out driving in the lanes Im really going off Syd

I would say alternator, but if you have had a new one recently i dont know

It wasnt a new one but it seemed ok :-? just tried again and the battery is now flat so will have to look at it tomorrow. I didnt want to go out anyway

or not enough tension on belt or worst case another duff alternator

check the return eath from alternator and the eath wires under the battery

Ok thanks will check in the morning at least if it is the alternator I know how to change that and I wont have to get the coal man to bend up the battery tray to get the bloody thing out as I could never get it back flat

I have tested the alternator and think the replacement has now died too. Have I just been unlucky or could there be something causing them to fail :-? This time it is a bit different as I charge battery over night, run kids to school  ( 15miles ) all ok, then car will turn off and re start. But if I leave the battery connected within 2 hours battery it is then dead. What would cause it to drain. I also have the old one I took off, could this be re conditioned :-/ Id hoped to sell Syd but Im sure he knows as everytime Im ready to place the ad something else fails and I have to delay selling him

Sounds to me like a rectifier has failed in the alternator and this is draining the battery when parked up. You might be able to replace just the diode pack, I suppose.

I would take the old alternator to an auto electrical specialist. They will probably be able to repair or exchange it. Changes are just fitting a new diode pack or regulator.

More importantly they should be able to test it afterwards to ensure it is 100%.
