Brief Description: Work on Trim and tested Aux Music jack
42D-19: Applied 12 volts to Pins 31 and 32 (wires from the P30 Harness) at the Tunnel d-sub connector and there was no movement of the AST. I know the servo motor works because I had tested the white wires before and there was movement. The problem could be in the Molex plugs or at the connections above the Panel Base. Disconnected the Molex connectors at the Tailcone. The pins (especially the ones on the white wires) did not appear well seated. Used a small forceps to advance the pins. Retested pins 31 and 32 with 12 volt power and this time the AST moved up or down depending on the wire with the positive lead.
31B-04: Crimped new pins to the 2 white wires from the P-30 harness and inserted the "Tab Up" wire to position 32 and the other wire in postion 31. This is a correction to the plans and was discussed in VAF.net forum which was verified by a Van's rep. Joined the 2 d-sub Tunnel connectors and checked the Trim Switch and now the AST moves. The trim motor runs 6-9 seconds from stop to stop. Tried adjusting the potentiometer but there was no noticeable change. Apparently, this is not so important if you have the SV AP Knob Panels because the trim rate is set by software.
42D-30: Connected an Ipod to the Aux Music jack. The sound was loud but the volume did not seem to change when the Aux1 left and right potentiometers were adjusted. The sound on the headset was distorted expecially the vocals. The distortion did not improve with adjustment of the EFIS left and right potentiometers.
The volume on the headsets is weak when listening only to the active frequency even with max volume on the GTR 200. However, when the Monitor button is On the volume is normal but you hear transmission in both frequencies. Will review the Garmin GTR 200 manuals to see how I can correct this.
