Right I bought a new battery for my rs2000 when I bought it around 4 months ago and its been fine since. I didn't touch the car for 2 weeks came to it and it as flat.


Ive jumped the car a few times now took the car out quickly to charge it up. Come to it the next day, flat again!


Now there is a alarm/immobiliser on the car and im thinking the standard battery might not be big enough to cope with the alarm.


Either that or I have a drain.


Ive took the battery off and have put it on charge to see if that helps.


Think I may get a big diesel battery on it


Any ideas

 

It's quite possible for the alarm to drain it after that time.

Taking it out 'quickly' won't be long enough to charge it.

Put a volameter over the battery and pull and replace one fuse at a time till you find the drain.

 

Have you checked that it isn't draining back through the alternator if the diode is faulty happened to me once

 

I havnt had chance to check anything yet.


How do I check if its draining back through the alternator?
