1998 Mustang Gt cannot get alt to work
i have a 98 gt and i cannot get my alternator to work for more than maybe 3 miles.
I bought the car 8 months ago and it never read past the R of NORMAL, but car started right up no light surging, power loss, or anything then one day car just dies i figure ok alt went out. So i buy a new battery and alternator and install car runs fine but still dosent rise above R so i started replacing some of alt wires no luck there. Took old alt and battery had both tested both were fine, battery was dead but had it charged and installed in different car it does fine. now my car has started acting up again and ive tried battery and alt again and some wires but after 2 or 3 miles gauge drops off and car starts to die. no battery light had everything tested and its all fine but im loosing my mind with this please help
