jump to start..... every time!

ok so i got the charging system checked and they said that my brand new alternator was only putting out 12 volts when it should be 13 to 14 volts and that i should get a new alternator is this true or are the just trying to sell a part?

Sounds like BS to me. Who checked it and what did they use?

Did you load test the battery?

The steps should be:

Charge and load test the battery

Bypass the regulator to see if the alternator is capable of full output

If the first two check out, then check the regulator wiring, and if that is OK, replace the regulator.
