Hi folks,the battery on my saph keeps draining overnight,took it out last week,charged it for 48 hrs,kept the battery off the car and checked voltage every 3-4 hrs,over 3 days it only dropped 0.6v from complete charge sitting at 12.91 for this time.
Put it back in the car on saturday,ran around in it on sat and sun,no problems,charging at 13.6v,went out to it today at 13:00,dead as a dodo.
I have checked the boot light,glove box light as I know this used to be common fault area's,all ok.
Looking for any other suggestions as to common places to start looking.

The car has cat 1,tracker and some amps but even with these it shouldnt be draining the battery overnight should it

Any help appreciated

Check the draw first to see what it is, then start by removing fuses such as the interior light fuse etc until this figure lowers, won't be glove box light as this only becomes live with lights.

dont think it happens as quick as that though,but I'll give it a try,thanks

 

If you remove the radio fuse etc as these are things that are permanently live which would be suspect, then if you leave the car and all is well you can isolate it to that area.

Another thing to try is disconnecting the alternator main wire, as the battery can discharge through the alternator if the diodes(one way electrical valves) are a bit iffy.
