Best Power Source ???
I am completing the installation of Cibie head lights and the relays for the low beam and high beam circuits. It has been recommended to connect the main power wires from the relays to the battery terminal on the alternator. The reasoning is that the power from the alternator is more direct to the new headlight circuit. This avoids the alternator having to provide power through the amp meter, existing wiring, etc, to reach the battery cable on the starter soleniod. Most people would attach to the battery cable on the starter soleniod. Which is best?
My ERA Cobra has an early Ford alternator (3 wires; battery, field and ground) and an external regulator. I believe it has about 64 amps output. I will use fuses on the power supply wires either way.
