On the RV-10 the battery is behind the baggage compartment so that brings some question concerning wiring here the part of Z101 which shows that: The wire marked with 1 (feed line aux alternator) would be about 14 feet long, I plan to protect that wire with an ANL 40A fuse on the FW close to the alternator, but it would be always (unfused) hot on the other side as the battery is directly hooked to that wire. The wire marked with 2 could be very short if the relay 704-1 is placed close to the battery The wire marked with 3 would be again about 12 feet long, but would only be hot when either relay is on. In this situation I would have 3 wire runs along these 12 feet #1, #3 and the starter wiring (I use 2 AWG there because of length) and #1 and the short #2 would always be hot. Now I could reduce the wire runs, if I would move the Alt Bus feed relay (704-1) to the front and hook #1 wire directly on point #4 to the relay,=C2- I would still have the long #2 and the short #1 wire hot. But in summary its still one hot wire run along the fuselage. I could mitigate that by moving the ANL fuse to the rear, but introducing a risk, if the Aux alternator is on, that the protection of the wire is on the other end of the source (Aux alternator). Many thanks for the consideration and tips on that question what is best or common practice.

I had a 30 Amp shunt break in the middle, which may have led to my engine-out off-airport landing in my Zodiac 601-XLB. A Hall effect current sensor, like the one shown in his schematic, seems a much more secure way to go, since the conductor whose amperage is being measured remains continuous. My question is what specific Hall effect device should be used? A less important question: Is my present gauge compatible, or do I need a new one? The present gauge reads "amperage" directly from the shunt. Not a "deal killer," if I need a new gauge. Cheers! Stu.
