charging

Battery will also do it if battery voltage is down... Alternator is charging so try charging your battery on a charger and not relying on your alternator to bring your battery back up cause it will never happen... little charger a couple of days and a big charger over night... give it a good charge on a charger and then see what happens from there

sounds like a bit of both.

As suggested, give the battery a good charge with a big charger adn have the alternator checked by an auto eleccy.

From sitting around and going flat - found a charge leak from the stereo, so disconnected the stereo and charged the battery. is in need of replacement but its doing the job at the moment.

It's the alternator.
This is not legal advice.

x2. Max of 14.7v on charge if memory serves me correctly. My alternator is due for brushes soon - taking a bit longer to excite these days.

Mate that charge rate you said sounds too low to me, I'd be very surprised if its not the alternator.

14.4v is a border line high... most cars with a bit of age wont reach 14v due to voltage drop in plugs etc... 13.5v is acceptable, obviously higher the better, but even with a new alternator you probably wont reach 14.4v

I'm currently managing with a brand new alternator, 14.3v normally (just a/c, stereo, uhf, normal day driving stuff) and between 13.7v and 14.2v with all lights, spots, a/c going.

alternators + mud = bad mmmk :oops:
