Hi All,
Hoping you can help!
B8 3.0tdi avant
The battery recently died (was old) so I replaced with a nice new Varta 110Ah last week
A week later it’s flat and showed 11.1v yesterday.
So I charged yesterday and got it up to 12.5v by end of day, and locked it last night
This morning it was down at 11.6v
I got my multimeter on the 10A setting and connected it in series with the battery terminal and negative lead..... expecting 3A if it’s draining somehow.... and it whizzed up to 13A and blew the multimeter fuse!!!
so have ordered a new fuse....
what could be drawing this much current please? When I reconnect the negative battery lead there’s a great big spark
- I installed the new battery properly and have driven it since
- what would cause such a big current draw?
I fitted a cheap Chinese front passenger door lock mechanism last week, which works fine, and when I disconnected the main door connector to isolate it, I got the same big current draw, so I don’t believe it’s that.
So I guess I now try and locate the large current via the fuse box, but may blow the multimeter fuse again?
many thanks
