First item on my list today was to move the headset power outlets from the main battery buss over to the radio buss. This was done to isolate the headset circuits from the main power during engine start. Headset power outlets have been installed in both crew positions to support ANR type headsets. I have already converted an older passive Peltor headset using Headsets Inc. conversion product and I plan to convert another set for the copilots position. Using aircraft power for the headsets will eliminate need for 9V batteries that only last for 20-30 hrs.
The next task and by far the most challenging was testing the starter circuits. As mentioned earlier, I installed a momentary switch on the stick to activate the starter so I can keep one hand on the throttle and one on the stick during engine start. This required including a 30Amp relay and new LED indicator lamp to be integrated into the standard starter circuitry. There isn't any published schematic so I had to improvise. The wiring still incorporates the std mag/starter switch so it can be used normally if desired. I had installed the wiring a few months ago so it took me a little time to "refresh" myself on the wiring scheme and figure out how to test it. Anyway, it tested ok all the way to the output side of the starter relay.
I finished the day by installing three of the required toggle switches including the stick starter switch enable, the rear stick enable, and the pilot map light switch.
