Classic rangie battery drain

Brookland_cleaver · Jan 5, 2015

My Dad's 1994 Classic Rangie is causing him grief at the moment. It's recently had a new alternator fitted as he was continuously having issues with batteries going flat if the car wasn't used for more than a couple of days. With the cold weather snap it's affected it again, so the battery has been replaced for a brand new one. Two days with my use and the car won't open using the key fob let alone start. He's even removed the interior lights in the car in case they're staying on when they're not supposed to.
He's contacted an auto electrician but I wondered if there was any known faults on this model?

Any advice would be greatly appreciated.

Lots of short runs and an alternator charging at 13.8 volts will kill a modern battery in no time. Modern batteries need 14.2 to 14.8 volts to charge fully.
If it has a current drain could be the alternator or any number of other things, it will be a process of elimination, pulling fuses to check/isolate circuits.
