Problem with flat battery

[Daniel]

I have new alternator, new battery all new belts, so everything should be working fine.

If i leave the car for a few days, it starts 1st time everytime, albeit a little lazy. However if i then drive the car for about 20-30 minutes (or longer if needs must) when i try to restart it, its as flat as a pancake. :S

Any ideas???

got to be alternator fault if it goes flat while driving. Maybe a connection as the alternator is new.

I could talk you through a diagnosis but id be better talking to the dog

I had a similar problem, turned out to be the lead connecting battery to chassis.

If it wont jump start via connecting the other car to your battery terminals, try connecting the negative cable to the engine (as this is earthed). If it starts now, it means you have a poor connection between chassis and battery. Apparently half a volt loss can make a difference.

wonder if it a connection issue or a bad cell in the battery or a poor alternator
