I am installing an EIS 4000, and just like many of my projects when I opened that little can a whole lot of worms stampeded out! I've managed to get a lot of them back in the can by rewiring, rerouting, adding cable ties etc. but I found one thing that I ahve not figured out. I have a 60 amp alternator with 3 wires hooked to it. One is the battery or high current wire, and then two smaller 16 ga or so wires in one three pronged connector.
When I traced the smaller wires to make sure where they went, one traced back to the breaker panel to the field breaker. That makes sense. The other one traced back to the panel lighting circuit. That did not make sense.
I checked the Van's wiring diagram the builder of the plane used but it shows the older style alternator that has a separate regulator. I also checked Plane Power's website and found a diagram for their 60 amp alternator that shows two wires from the connector that both go to the "Alternator Field" circuit.
Any ideas about this? Is that the proper place for it to go? Should I reroute it to the Alternator Field circuit?
