I had left the mini sitting for a period of around 6 weeks and stupidly hadn’t and it during that period. I jumped in it and the starter motor just clicked , I thought the battery was just dead so I put jump leads onto the front and the starter turns but it sounds like it’s turning slower than it should and after a few turns it dies , almost seems like it’s not getting enough juice . I’ve charged the battery up and still the same . Tried jump leads on rear of car and still the same . I thought it be an issue with the starter motor so I bought a replacement , fitted it yesterday and still nothing . Starter motor turns once at most at an absolute snails pace . I also checked the engine to chassis earth and that seems ok . Any ideas or suggestions would be greatly appreciated. I’ve had a look through the search but can’t see anything that seems similar .
