I am installing a P5 into an engine with battery and airwire decoder. I was hooking everything on a bench for a test and the chuff was set to work automatically. I plan to use the reed switches to trigger with magnets, using C2 pins 3 and 4 for the reed switch per the manual had no effect, I tried intermittently touching the wires together to no effect. The P5 was programmed at the ECLSTS for a K-27. How do I get the auto chuff switched to manual triggering? The manual does not cover this point that I can find. Thanks.
