My car broke down about a month ago. I had trouble starting it at home one afternoon and eventually got it to work, but that night, in the OGGB carpark, it refused to start. I delayed doing anything about it for a while, since I didn’t really have either the time or the money to deal with it, so my car has been abandoned on level 3 of OGGB ever since. It’s not just a battery issue since the lights and electrics all work perfectly fine. Given that the car has been getting harder to start, and now won’t turn over at all (I just get a click) my conclusion is the fault lies with the starter motor.
