Help?? Engine has a Select ignition module. Left the cutoff switch on overnite, drained battery. Now alt. only shows 12 amps., squeals, and engine, when it does run, misses and hits only on 3-4 cyls. Did I toast the module? Is the alt. not putting out enough amps? Should I just go back to points? Engine from 83-84 F150, 65 coupe. Thanks
