Question regarding fuses. In the Autometer instructions they "recommend" adding a 3A fuse (4A for Tach) inline on the power wire to each gauge. I am trying to determine what would be the correct fuse rating to use if I wire all the gauge power wires in parallel, and place the fuse before all of the gauges. I may be wrong, but I suspect it is not as simple as saying there are 6 gauges on this string, so (4x3) + (4x1) = 16 amps. If it is that simple, I suspect is would want to use a 15 amp fuse, not a 20 amp fuse. Any help is much appreciated.
