are you running overdrive pulleys? that will give u a low output.... check your ground cables to make sure they are making good contact... corrosion on battery post......good luck!

^^^ what he said and you need to change your voltage regulator along with you alt as well if you have not already done so. It will do this as well.

Thanks guys. I'm messing with it now. I thought the voltage regulator is in the Alt?
Some one also said to check the fuse link?

Wondering if solenoid would have anything to do with it?
I recently changed it, and new one is slightly different?

This is a voltage regulator. Yours may not look exactly like this but it will be similar. It may be black or silver and will be bolted to your tower wall next to your solenoid with a bunch of wire coming out of it.

Now I come out here to start it up and it is operating normal.
Is it normal for cold start to be good, then when it war ms up to stop charging?

Ok I goofed up. I am use to older Mustangs and did some research on yours and you would have an internal voltage regulator so this is not the issue. Sorry :oops:
