Hook up the voltage meter to the battery, then watch the voltage drop from the said 12.9 volts when cranking the engine .
Now if voltage drops below 10volts then replace the battery. If voltage is above 11 volts then repair battery starting circuit . Meaning cables and the starter itself which is probably the problem.
Check this out then please get back to me.
