so i drew up this little diagram that someone else may also find useful........

i plan to print it out and keep it inside a ziplock baggie in my tool kit "just in case"


Are you running signals on this setup?

I'm not sure about HD's (I'm very new to them) but on older cars that diode is there to allow the alternator to be excited, even if the light is out.

When you turn on the ignition it powers the light which is then grounded through the alternator and the light comes on, when the car is started and the alternator provides power it pushes 12v back at the light and the two 12v leads feed into the light from both sides and the light goes off. The diode is there to make sure the alternator is excited even if the alternator light goes out. The diode, on a car anyways, is wired in between the two terminals on the light.

Additionally - In theory you can run a light only (which is how I built my Jeep) or a diode only.

Yup only diff is the old ironheads use Generators but your explanation is right
generators dont charge at an Idle so this is why your light is on at an Idle and goes out once you pick the Idle up and it starts charging

Default Diode Question

How do I make sure the diode is in the proper direction? I have done some wiring before but have never had to mess with adding a diode.

The band on the diode is on the generator side (away from the light)
