Help needed 🙏🙏

I have a Ford Focus MK2 1.6 Petrol LX. The battery kept dying randomly, then starting afterwards, was like that for a few weeks. 

Until last week were the car battery completely died. We changed the battery with a new one when I got paid

Still wouldn’t start, multi meter showing the correct voltage, the battery was working in my friends car. 

We tested the alternator which was fine, also all the fuses under the dash, the ones next to the battery. Battery earths are fine. Not the clusters 

We’ve tried jump starting it which is no luck. But only starts when being bumped started when going downhill 

No sound coming from the starter motor was clicking before the battery died but now nothing. 

When we went under the car it looked the rubber come off the starter motor wires 

Our mechanic doesn’t to touch the starter motor as he said it’s in weird place 😒.

We think it could be the starter motor or the wires connecting to the starter motor. 

Any help or advice would be appreciated, as the car is sentiment as my nan paid towards it before she died.

Thank you 🙏 🙏

Not sure what the problem is here.  It's right at the front of the engine.  Bit awkward to access, but no more than most engines.

I would 99% agree. You would be extremely unlucky for it not to be the starter motor, or more likely the starter solenoid.

When you do eventually replace the starter motor (with combined solenoid) if you find it does nothing then it is quite probable that it may have blown the fuse for the starter relay.
