This sounds like the wiring from your vehicle's alternator to the battery might be having a problem. Think of the battery like a lake and the alternator is a river that is being diverted to fill the lake through a hose. If there is a problem with the wire, it would be like getting a kink in the hose. What happens when your garden hose gets a kink in it. No water. The same goes for wires in an electrical system. So let's see if the wiring is the problem here. To do this you will need to use a multi-meter and a test called a voltage drop test. I have included a link down below if you are unfamiliar with how to use one below:
I have also included how a voltage drop test works in the diagrams down below. We are going to want to do a voltage drop test on the black wire with an orange stripe going from the alternator to the battery. So with a fully charged battery you are going to need to start your vehicle, letting it idle. Have your multi-meter in DC Volts and put the red test lead at the black wire with the orange stripe on the alternator and one on the same wire at the battery. The voltage should between 13.5 - 15 Volts. If not then the wire needs to be replaced. Please get back to us with what you find out.
