I have a 2000 GT that has had the battery light on since I bought it 1.5 years ago. Got it checked out at Ford when I bought it. They said the electrical system checked out fine and it could be the aftermarket alternator. Drove until a couple of weeks ago and battery died. Alternator seemed to be issue per check at auto parts store. Replaced alternator with 130 amp instead of lower amp one installed. Also replaced battery as it was dead also. Battery light now kicks off just over 1700 RPM but comes on below that. At idle I'm still only reading 12 to 12.5 V. I have the Mach audio system and saw a thread on the amps creating a drawl on the battery. Pulled both plugs on amps but still same voltage. Have cleaned up battery terminals and ground connections. Alternator wire was spliced also. I cleaned that up with butt connectors. What am I missing? Corrosion somewhere? Fuses? Appreciate and thoughts or ideas.
