Ford focus zetec, iv put in new battery but something still keeps draining it. I had alternator checked at kwikfit and it tested ok, but still battery keeps draining.what can be causing this if its not the alternator? Or could the alternator test ok even if it has a fault? Also the speedo keeps dropping and petrol gauge of its own accord, is this due to the same fault? When iv changed the battery the revs stick on again of its own accord. Weird I know �� its driving me mad as cant find the fault, please can anyone help

I think the alternator is probably bad. Seems to be the most common issue.

Five miles of wire and 50 devices in a car that can all run the battery down. Could be literally anything.

This is known as parasitic drain.

Lots of info on this forum about it. Do a search and you will see many threads.
