As was hoping if I swapped out the LED for an incandescent or just eliminate the bulb, the alternator might charge at 13.5 to 14 volts? Thinking maybe the excite wire with LED might be confusing the alternator to charge at the higher rate. I was watching a video last night that showed the bulb coming on when starting the car, but going out when the engine got running. Made me wonder why my LED was not turning off.
