Today I continued with wiring the SD-8 and it’s components. I have a copy of the Z-13/8 drawing in the hangar, and I’ve been drawing lines on the diagram to note wires that are complete. First, I made a hole in the firewall for the alternator output wires.
Then I ran the wires to the circuit breaker, which is part of the crowbar over voltage protection.
Next came the wires to the switch.
The wires from the shunt go to a double pole switch that will provide a selection between the two ammeter measuring points.
