Further to this alternator, battery voltage thread.
I've just come back in from testing the alternator output with the engine ticking over. ( Diesel. )
1/ Nothing electrical switched on.---14.55 volts. approx.
2/ Dipped lights on. ---14.53 volts. approx.
2/ Head and dip lights on together. ---14.50 volts. approx.
The battery voltage before I started the test was 12.65 volts.
I now and then check the battery the day after the car has been in use. It varies from 12.6 to 12.75 volts.
My car will have been on the road 16 years in December and the current battery is number three. ( In use 4 years, approx. )
The alternator has never been touched.
It would seem then that the car electrics and previous batteries have all been happy at the above mentioned voltages.
From this I would suggest to the OP that he has nothing to worry about with the reading he gave us of his alternators output.
