Dead starter single click information

This might help someone. Recently done a timing belt on a 1.6ti 2006 focus. It was bit of a rush job and didn't personally testdrive vehicle after. Car is not used much and was took out a couple of weeks after the timing belt only for it to fail to start after 5mins of driving after being shut off. Symptoms described was a single click. Car was recovered and I took a look this weekend some 4 weeks after the issue. Battery was down to 11.7v turned engine over by hand before attempting to start to make sure not valve to piston issue and no problems. Jump start still just a single click Bump start worked. Car drove 2miles and it conked out again and had flattened the  battery. Went back out to the car and I noticed I hadn't reconnectedthe main terminal or the plug to the alternator when I done the timing  belt! So Car worked a while until it killed the battery. Managed to get it back to my place by swapping batteries from a working car and Bump starting. Multimeter showed  no continuity between positive and alternator. So what had happened was that the main terminal on the alternator had shorted to the engine and blown the fuse that sits in the main cable just after the battery. Purchased a 175 amp OTO strip fuse from halfords and drilled and bolted it inside the standard plastic holder 😉 car ran like a dog after but connected laptop and cleared the numerous codes and car back fine.
