Radio trasmits.... dimmer circuit wiring
I cleaned up the wires for the switched in/out power since I had just used a wire nut to connect them yesterday. Then I worked on wiring up the PTT in the stick grip. I connected the grip to the terminal switch under the seat and armed Sandi with the portable and did a mic check. It works! Whew... that's a relief.
Next I started working on the dimmer circuits. I bought the LC-40 dimmer from Van's. I fussed around with a location to install it and decided on the firewall side of the sub-panel. I pulled out the instructions and tried to figure out the wiring. The instructions are in color but the wires going to the dimmer switch weren't colored correctly (two blacks) so I couldn't tell exactly how to wire them up. The instructions clearly say if you have trouble to call... so hey.. it's Sunday at 12:00pm.. maybe I can reach someone. I called and no answer so I went about just stringing wires to the dimmer and about 20 minutes later, sandi radioed me that someone was on the phone. It was Flight Data Systems.... they saw the call on their caller-id and called me back! Talk about service! He said I wasn't the only one to call about the wiring on the switches and gave me what I needed.
I wired up the two led 'map lights' I installed on the sides of the cabin. They work great! (At least the come on and dim.. i need to go out there at night and see how bright they are.) I installed the dimmer switches on the inboard facing surface of the F-721A forward canopy deck. Ray did this on his -9 and I liked it.
I wired up the the 89B, audio panel and transponder to the dimmer and installed the dimmer switch on my center console at the top. The Garmin has a problem with the dimming circuit... it pulses when set anywhere between full on or off. I'm not sure what the problem is or what the solution might be. The 89B and audio panel dim just fine!
The fourth dimming circuit will be the instrument lights.. which right now only include the compass and fuel gauge lights. I also need to wire in my music input jack.
Not sure if I should be embarrassed by this wiring mess or not... it sure is hard keeping things neat. As long as it works, I guess I'll be happy.
