Built cable to add the ECB to the EFIS/iBox CAN bus. Took several tries setting the WCB DIP switches to set profile 31, permiting circuit breaker programming through the MGL EFIS. EFIS/iBox/ECB testing of power input from Power Conditioner appeared to blow 5 amp fuses ahead of the iBox. Tested MGL wiring harness for shorts but nothing evident. May use the power conditioner to power radio/transponder circuit. When the EFIS is powered through an WCB breaker, switching off the EFIS then requires cycling main power to ECB to re-enable EFIS (circuit programmed to ON during power up. Researchning how to display current through ECB circuits.
