Brief Description: Added hoses to avionics fan and wired some LEDs.
Well, I found the cheap Harbor Freight unibits are not that great, but they did manage to burn a one inch hole through the middle forward rib for the snap bushing that holds the hose for the right side EFIS cooling. I won't use it that often so it will work, but its no Klein tool quality. We put the battery in the box and checked out the fan and it worked good.
I decided to wire the power wires for a couple of the LED warning lights. The Aternator Fail light gets its power from the Main bus and only lights up when the Plane Power alternator fails (blows a 5A fuse) using its internal regulator crowbar function. The wire from the bus to the LED has a 1A fuse and is grounded at the alternator when it fails, thereby closing the circuit for the red LED.
The other green LED is wired off the Fuel Boost switch and comes on as a reminder when the switch is on. I crimped the LED power wire in with the faston terminal with the wire coming the Main bus to the switch.
Avionics fan hoses go to the left EFIs, middle radio stack, and the right EFIS.
