Ground terminals HIC and ECU connectors
Posted: Thu Dec 21, 2023 12:59 pm
Does anyone know what to do with the four 6mm ring terminal grounds in the Rotax 915is wiring harness near the HIC connectors and the ECU connectors?
We attached them to the airframe at first, but in the Rotax documentation we think they instruct us to connect them to Reg A of the fusebox (in that case we have to make another isolated go-thru the F/W to Reg A). But we read mixed advices on that subject on the internet. Some say to the airframe ground, others say Reg A/EMS ground. What is the right thing to do?
