Check battery operation light keeps popping on and off

Hello, a battery reads in volts and amps. Ohms is a resistance measurement that is checked for wiring concerns. I'm sure it's a simple mistake in explanation. 12.4 volts would be somewhat low for a normally operating vehicle. Your charging system may ready 14+ volts, but what if the amperage reading is near zero? Volts don't do much for you if you have no amps! You need proper, professional testing at the correct engine speed to know what's going on, then a good physical inspection of the wiring and alternator also.
