some cars only run at 13.8 volts. does it have a built in voltage regulator? or does it use the car's regulator? are you measuring this while playing music? have you done the big 3 yet?

What rpm does the car idle at? Standard or auto?

ugh foreign cars. i always see people having problems with HO alts on foreign cars. best bet is too e-mail irraggi and see what he says

rpm at idle is around 800. its standard

It is not a problem. As long as you are above 13v you are perfectly fine, that is the normal range. As you accelerate, the alternator should put out more and the voltage should rise.

But no, you are not supposed to be at 14.4v.

Ah, didn't even see the battery light part...

Have you driven the vehicle since you installed the new alternator? If not, you might have drained the battery a bit while working with the door open, or something like that. Maybe it just needs a good charge..

The battery light should only come on when the battery is below the 12v region, are you positive you hooked everything up correctly?

yes everything is hooked up correctly.. car drives fine starts first crank no problems what so ever. i charged the batt all last night still the stupid batt light....

You try to make your sig seem all professional and then spell "install" wrong.
