If you put a freshly charged battery in and the car runs you should use a voltmeter to then check the voltage at the battery. It should read approx 14.5V. If you are only getting battery voltage(below 12.6V) then use the voltmeter to check the voltage at the alternator. Connect between the alternator housing (-)and the main bolt on connection(+).If you are getting 14.5V there then you have a bad connection in the charging circuit between the alternator and the battery. You should also check the voltage at the alternator with the engine off. It should read the same as the battery. If you have no voltage then the problem is caused by the main + cable being open circuit. This could be the fault of the alternator fuse.
