1997 Questions for all other cars Automatic 140000 miles
----------------------------------------------------------------
hello,

We have a Rover 800 i automatic with a brand new battery but when we leave the car overnight, the car battery gets discharged, completely and we have to charge it all ovver again even though it's a new one. we checked if we left the lights or else turned on during the night but nothing like that.
could it be a didode problem?

thank you!

Hi there,
You well may have a faulty diode in the alternator. get a current draw test done on the electrical system and if you have an excessive draw with ignition off & door closed start to pull fuses to try and isolate the circuit.
