Battery Charging Problem - I Think Anyway

[grahmmie]

Hi, for the last 6 or more months my 1996 Corolla 1.3L GS Battery keeps going nearly flat if not used for a few days. The first 9 months of ownership were problem free.

At first I thought it might be the Battery so I replaced it. The car worked fine for a couple of months but then the same problem re-acurred.

I've checked the belts etc under the bonnet and there all tight with hardly any slack in them and they look and feel very new with no sign of wear and I can see them turning when the engine is running.

I'm guessing there might be a problem with the altenator. Does anybody have a rough idea how much it might cost to get it looked at and possibly replaced? I've no idea what the approx cost might be.

Or if you have any other idea's as to what might be causing it.

I do have an in-dash Dension mp3 unit but i've only been running the radio for the last few weeks and the Battery still went flat. I can also hear the hard drive power off and see it's light go out when not in use so I dont think it's this.

Many thanks
