While traveling my radio and refrigerator stopped working. The red light came on one of my Magnum inverters came on. I cranked my generator, and everything came back on. Should me 12-volt generator keep them on, or will bad batteries cause this? My 12-volt generator is charging 13.4 volts. Could I have a problem with one of my inverters? Any help would be appreciated.
