alt low output ?

[natas]

2005 f350 single alt

my battery light came on last night when driving home .so im guessing my alt is toast when my rig is running its putting out 11v ? shouldnt it be like 13.8-14 ?

11 is way too low. get it worked on before you need to replace batterys and the ficm then maybe injectors. an alt is way cheaper than the other three.

so i replaced the alternator drove it for a day damn battery light came back on on my live wire screen its dropping to 10-11 volts on my batterys ? im thinking i need to replace both batteries ????

[van-boy]

after i replaced my alt, i had to replace my batteries also. do both of them, the weaker one will draw from the new one and you will eventually have to replace both.
