Hi all, I have an issue with my Focus draining its battery. Its had a new battery and alternator last year. The alternator is charging the battery as I've checked with a multi-meter. I've gone through all the YouTube videos to find the draw and not found it. So now I need to get an auto electrician to have a look.

It seems hard to find one. But one has said £110 to run a parasitic draw test for 2 hours and if in that time he can find the issue and fix it then that's included. Does that sound fair?
 
Got a dashcam installed? I had a really strange issue where my dashcam suddenly started draining the battery - the hard wire kit is supposed to cut off when it gets below a certain voltage, but that wasn't happening for some reason.

If you're relatively tech savvy (and have the time), then a multimeter is cheaper than £110

Have you fitted anything like a new head unit recently? Or anything electrical?

No nothing recently its all as standard.

I do have a dashcam and thought that could be the culprit. But I removed it and still had the same issue.
I went through removing all the fuses with the multimeter attached and still had a large current draw of around 2 amps. So maybe I missed something or its something I can't see. But I've looked so many times that I need someone with experience to take a look.
 
Checked both fuse boxes?

Quote wise, that sounds OK for 2 hours work, but obviously if you can fix it yourself it saves a few beer tokens :D
 
boot light? 2amp is huge i was chasing milliamps for ages till i found a bluetooth module not shutting down. dont know what year the focus is but if i remember correctly early ones had problems with the fusebox not shutting down everytime and leaving dash etc live worth looking at, but seriously 2 amp should be fairly straight forward just unplug certain items.
just a question..might be silly but when you connect your ammeter in circuit you are locking the vehicle and allowing the fusebox to shut down before measuring, takes about 20/30 seconds to do it. opening a door will reactivate it.

i had a customers honda that had a electronic oil level in the sump , that little devil stayed live and flattened a battery in 4 days , wired it out and told the customer to use his dipstick lol.
 
Check the wiring on the alternator for the smart charging system, plug with two or three wires, the wires break and the alternator doesn't output the correct voltage, there's a few earth straps in the bay that if crusty can effect charging.
