I hereby deem the cowl and baffles to be as finished as they're going to get, at least for right now. To celebrate I removed the forward top skin – which had become quite dusty! – in order to get caught up on some wiring tasks.
I connected and secured the standby alternator field wire and B-lead… note adel clamps and strain relief:
I had previously mounted the current sensor for the main alternator, but I never got around to wiring it or installing its twin that measures current from the standby alternator. The second sensor I installed with an adel clamp from the engine mount, right above the fuse holder where the standby alternator B-lead connects. Since these are 100-amp sensors and the standby alternator is only capable of 20 amps, I looped the wire through three times in order to achieve a little better resolution on the display. A calibration step in the G3X software allows you to apply a scale factor of 0.33 to account for this trick.
Here's a wider shot showing both current sensor hookups. To make them serviceable I used mini molex connectors, which are shown here prior to being secured in the wire bundles.
I wrapped the connectors with silicone tape in order to make them somewhat waterproof:
Then I powered up the avionics and calibrated both current measurements to zero. The machine is starting to wake up…
