I still have a 6 amp drain on battery which flattens it over night. i have pulled every fuse and relay one by one but non have had any affect on the multimetre showing the 6 amp drain.
have fitted a new alternator with regulator because i read something on google that it is possible to get a drain back to the alternator.
No affect there.
Does anyone know what the small elecyronic connection does on the negative battery lead connection and on the positive side the little box of tricks that goues to the terminal which does click when im searching for the 6 amp drain
