I got an order from Aircraft Spruce today with some 6AWG wire, so I fabricated the wire from the output side of the alternator current limiter to the Vertical Power VP-X. Here’s the alternator current limiter end of the wire (protected by the boot). All of this metal down here is hot when the master contactor is closed. I need to research if it is necessary to shield all of this in case something were to inadvertently connect any of this to ground.
Here’s how the wire is routed up to the firewall pass-through. You can see that the wire to the battery bus (the one that forms a U shape right in the center of the picture) also follows this wire up. Behind the VP-X wire is also the alternator field wire. I’ll be installing a few more adel clamps and some high-temp zip-ties (replacing the cheap zip-ties currently installed).
Here’s where the main VP-X wire comes through the firewall and drops down under the subpanel support rib through an additional adel clamp I installed just for that wire. Being 6AWG, it’s fairly heavy (especially when pulling 6 Gs), so I want it well supported. You can also see that I installed the main battery bus with some hardware that also showed up from ACS and connected the battery bus supply wire. You can also see the alternator field wire (the small white wire in the upper right) has been cut and connected to the voltage regulator. Finally, I connected the voltage regulator ground wire (the black wire in the upper right. I could have taken a short-cut through the rib lightening hole and made the wire substantially shorter, but I’m trying to keep all the wire bundles neat and organized instead of running them haphazardly around the plane.
The VP-X supply wire has a short straight shot from the bottom of the subpanel support rib to the VP-X power post. I installed a boot on this end of the wire as well.
