Re: Help with Autowire kit!!
By OE design, when the ign switch is on, engine off, one side of the bulb has ignition voltage applied.
The other side of the bulb filament has a lower voltage from the alt, almost zero volts, and bulb is lit.
Start engine, alternator starts to work, alt now supplies voltage on the same wire, GEN light is out/off because the same voltage, or close to it, is on both sides of the bulb filament.
Sometimes, as you asked, the power on the brown wire from the alternator will backfeed to the ignition system and engine continues to run - remember, the other side of the bulb, pink wire, is connected to ign circuit, power can run both directions. Therefore, a diode is installed with the line end of the diode going to the bulb.
