Flat Battery/No electrics

[Huw]

Hi, i put another post in about a week ago about a flat battery, well i bought a charger charged the battery (which had almost no charge)and everything was fine, until today when the alarm wouldnt work. Turn the key, very faint dashboard lights. I took the battery out, put it on charge, and it was about 60% charged. Is there a problem? i'm going to have the battery and the alternator checked tomorrow. I've heard that a cat1 alarm system doesnt run the battery down too much as long as you drive the car at least once a fortnight, and we've been driving the bongo every other day since i recharged the battery.

any tips/hints?

cheers

Sounds like you've got a big short or the battery is stuffed & not holding charge. If you've got a multimeter, check to see if there's a current drain from the battery , if so, check each circuit for currnet drain with everything switched off.

Put a volt meter across the battery terminals...It should read about 12.7 Volts and 14.2 Volts with the engine running (alternator O.K.)

Missed the driving every other day bit, on that basis, as Haydn said, alternator is the first suspect.
