Focus 2001 1.8 TDDI - battery drain

[.Mike.]

I've no idea what is causing my battery to drain overnight.

I've started with buying a new battery. I've also tested the alternator - it was giving almost 14 V when the engine was running - so it was ok.

Then I've connected the multimeter in series to the battery and it showed that something was taking about 0.67 A (sometimes 0.31 A) when the car was sitting.

I started to pull out the fuses (the ones which I could myself) but it didn't helped at all - the value was still the same (0.67 A).

I've disconnected the alternator and the value changed to 0.01 A! I thought it has to be a faulty alternator then, so I bought a new one, connected it and now (while the car is sitting) it takes 0.07 A - it's a lot less than before, but I've read it's still to much. I've read that there shoudn't be more than 50 mA (0.05 A).

Has anyone got any idea what can be wrong?

.05 or .07 is no big deal as the temp get colder the draw will increase slightly. Now that you have a new battery and alternator you are set to go.

I was told buy a rebuilder of alternators and starters always always replace your battery once it reaches 5 years. This is the best thing you can do to save your alternator, In some cars alternators may cost more then $800 and upto 4 hours to replace
