Default Re: AU1 5.0 battery level dropping

Your battery guage on your dash will tell you if the alternator is charging, if the needle is over to the right (14.3v) its charging, if its over to the left (13.2v & under) its not. Check with the multimeter at idle & look for the numbers i mentioned.

If your Xr8 is a s1 & your alternator is stuffed the easiest way out of it is to get another good s1 alternator unless you have the cash to get a auto electrician to convert a new s2 alternator to replace the faulty one, good luck!

cheers, Maka
