The instructions for connecting the dynon heated pitot control module say to extend the three non-terminated wires coming out back for power, ground and status light. They give a chart for length and recommended wire gauges. In my case, I'm looking at a total run of just over 16 feet, so by the chart I should use 12AWG. But the wires coming out of the control module look to be only 18 or 20AWG. Is this not a problem? All the current coming down that 12AWG wire will pass through the 18 or 20AWG wire to get into the control module. So if I need 20AWG wire for most of the run, why isn't this a problem when it gets funnelled into the small wires coming out of the control module??
Or is the idea that by using 12AWG for most of the run I keep the current from being too high, because the resistance across the long run will be lower... ok that must be it...
But it leaves the question - how do you go about splicing a 12AWG wire to a 20AWG wire? The butt splices I have are sized the same on both ends...
