I have a customer that has two of my E/PMag electronic ignition monitors (Electronic Ignition Commander- EIC). He never installed the first one before he purchased the second one (two aircraft) - love that kind of customer. But, he was having a fit getting my EIC unit to communciate over the Rs232 ports with these electronic ignition units.
Not being the electronics type, he had hired a technician to wire up a plug an harness for him. After several days in which we found and solved other wiring issues, the customer found the pins to one plug as shown in the photo. It was naturally shorting out the serial comm when the excess wire poking out of the pins touched. I would say he should find another technician {:>)
But, thought I would show the group the pins of this poorly wired plugs (can you say "electrical short"?) - so you can feel even prouder of your "amateur" skills {:>)
