Jumped in the vehicle today turn the key, nothing but a little click. Looking from the front the left hand battery reads 12.36 and the right one 12.24. My garage man via the phone says it should start. I have put some jump leads on from another vehicle still nothing. It worked perfectly well 2 days ago. I have tapped the starter motor with a hammer, still nothing. Any thoughts would be welcome. One battery is 7 years old the other is newer. But the readings seem to be OK.
