Dynon Cable Tester

DYNON Circuit Tester

I am planning to make all my own wiring harness for the Dynon system. To save fabrication and trouble shooting time, I made a simple cable tester. This way I can test all the DB-9 connectors as I add them to the harness o ensure the wires are connected properly and the phasing of the twisted pairs is correct.

The tester which uses a small 3 volt battery to power the LED’s and some diodes to ensure the phasing of the coupled pairs. The label was printed out on paper and glued to the circuit bard with spray adhesive.
