I mounted the final component to the bulk head today, a 5 position fuse box that I will use for the shunt sense wires & allow for future system expansion if required. I also connected the generator fuses to the shunt with the integrated generator disconnect relay in series. The function of the relay tests OK, 10awg wire is being used for both generator's outputs, more than reqired for the integrated generator & the minimum recommended by Rotax for the external alternator.
