To start off with I double and triple checked polarity and orientation of all LEDs I installed, and that they do illuminate when powered up. Cleaned all connections with aviation contact cleaner and a new pencil eraser. Used a 12 volt power supply and powered up each circuit to verify continuity on the wire trace and all warning lights illuminate as they should. Background lights turn signal indication and high beam indications are all normal. I get seatbelt warning when key goes from off to on for about 15-20 seconds, and that is it. Check oil light illuminates when key is turned to start position then goes out. I pretty sure that all warning lights should Illuminate when the key is switched to the on engine not running but they are not. I might just go back and install the 194 bulbs in the warning lights, but for some reason I want the LED bulbs to work. Any Ideas????
