Hi All: Anybody upgrade their alternator to a 115 AMP. Leastways that's what I think the high output generates. This is for an '86 5KCSTQ. With everything running (rear window defrost, blower on high, headlights, etc.) I only read about 12 volts, sometimes less. Running down the road I get 13+ volts. Any thoughts or BTDTs appreciated.
