I fabricated several 26AWG fusible links for the sense wires connected to the starter contactor and alternator shunt. Here’s the one for the starter contactor.
This attaches to the right post on the starter contactor so that the VP-X knows when the starter is engaged. You can see the two additional fusible links below the starter contactor. These connect to the shunt.
Here’s where these fusible links attach to the shunt. Before connecting these wires to the shunt, I attached the battery charger to the alternator side of the shunt to determine the correct orientation. Attaching the two sense wires to the wrong sides of the shunt would result in a negative current indication from the alternator. If I didn’t determine the correct orientation now and got it backward, it would require reversing the sense wires at the EMS end which would be challenging once for the forward fuselage skin is riveted on.
