Hi
I really could do with some help
I have a skoda octavia 19 tdi 2000 model the problem is my battery drains all the time at 12v I have removed fuses one buy one and relays while testing battery with a meter and it still shows it draining so I cannot pin point what is causing the problem, Under the bonnet there is a box ontop of the battery where some power wires are I found that the main thick red wire seems to be where the draining is comming from, but this appears to be the main power wire so I cannot isolate the problem freom there. I have had new batterys so I no its not a battery fault, also the car has been connect to a computer diagnostic machine but did not show any errors which is strange. So I have to disconect the battery every time I am not using the car. which is not ideal because this resset everything. Since this has happened the abs brake light now stays on but the abs seems to work but I have been told that low battery can trigger this light to come on. I have also taking the connectionss off the alternator but did not make any diffirence. I have also changed the starter motor with no luck so can any one help I really need some help.
thank you
