My mustang has been sitting for 2 years almost. Have been starting it regularly, went out this morning to start it and it wouldn't start, jump started it it was fine. While driving the Battery Meter goes from mid way between 8 and 18 up to 18 and the Battery light and AMP light pop on. got battery and alternator tested it tested fine. Any suggestions?

Have the alternator load tested again sounds like the voltage regulator is not controlling the alternator output-double check the wiring
