my alternator is charging 16 volts could this be the regulator and wht casue them to go as the alternator is about 6 month old from new battery whent dead and i left it for 2 weeks started and 16volts

 

16volts? Its fucked!


Sorry if thats a bit brief!

 

Is your meter reading right?

yes as i have the one on my turbo timer and the one that come with the escort cosworth and i just tested it with a multymeter its got to be regulator

 

i'm pretty sure a dry cell in a battery can cause the alternator to kick out too much juice (but i may be wrong). Could be worth getting another battery to stick on to see if its still doing it??

 

a healthy battery should be charging more than the 12v.

mines is about 15.

 

well my battery is shit as it goes dead in 1 week if left plus i had left it 2weekd flat totaly will go now and cheack if the battery is dry but could this realy cause :? a low battery

Should'nt it only be around 14volts with every thing turn on ie light fans ect ect But if the battery keep loing charge then its probly best to change it and see whot volts its running

 

Your battery could be shit because your alternator has cooked it!!! Usually a fooked battery will only provoke up to around 14.5v, not 16.

 

Alternators can overcharge, which then leads to your battery getting fried!

Take it to a garage or a decent spares shop to get it double checked if you're not sure... should be mid to high 13's really.

 

right every one has got the wrong end of the stick I run my own garage so I am not stupid just asking if the regulator on the alternator is fooked and causing it to give out 16v as it use to be 14v thanks anways

 

sounds like a alternator regulator problem to me....

thank you thats what i have been saying

 

the internals of the alternator are obviously working well, but the regulator isnt controling the amount of charge being produced , this is probably what killed the battery in the first place...

 

Sounds like the diode pack on the back of the alt change that first they are only about 12 quid.

 

I had this once - 6years ago infact...unfortunately I did completely the wrong thing & ignored it thinking it was ok - it fried my battery, ECU & headunit in the process!!!!
