Honestly I don't know, but if it connected to the power source and you spin it with hand, it is unable to start again. But we found one of the carbon brush (from 2) very dilapilated. The second one is dilapilated, too but a bit less. Is it possible to buy carbon brushes for Focus and if yes, where to find them? We found them for siemens, bosh, valeo motors but we don't know who was the manufacturer of our motor.
Or should we change the whole motor? The problem is that this Focus is a hungarian one and the motors we found on e-bay for Focus MK1 does not look the same type. Mondeo's does or very close. And german web sites have the same type for Focus so I am just not sure that we can buy an appropriate one here. But without blowing car is dangeous, can become very hazy inside... this is why we thought that maybe repair would be better than a full change.
So we are a bit clueless, sorry and many thanks for your help!
