All,
I have a question concerning ground loops. I am presently installing a King KT76A transponder and an Odyssey EFIS/EMS. There are instructions to connect one or two ground wires between the two units and there are several ground wires on the plugs of the transponder as well as the EFIS - three on the transponder and four I believe on the EFIS. Does each ground need to be taken to a central firewall grounding point I am providing for the panel installed equipment or can grounds as they leave the connecting plugs be combined into a single wire to continue to the central location. If I understand ground loops correctly each of those ground wires is electrically connected within each instrument as well as throughout the airframe in general and therefore would/could cause ground loops if parallel grounding routes be created to the central grounding point. Combining the ground wires close to the unit would not eliminate the loops, but they would be considerably smaller. Old hands, which should I do?
Thanks! Cliff
