It should activate a light if moisture is detected. I found the link below which has a nice sensor, but requires a lot of fancy accessories. I want simple. Has anyone installed something like this or come across a source for a thermocouple that senses moisture? http://www.smarthome.com/71932/X10-Water-Moisture-Sensor-CR1/p.aspx Thanks Glenn E.

There's a lot of confusion between what is "allowed" and that which is no longer "common practice". As a general rule, the folks-who-know-more-about-airplanes-than-we-do will not indulge themselves in bans on specific products unless they're involved in a safety of flight issue. We've always had an interest in fabricating one-wire, 'serviceable' splices in certain wires. If one wanted to avoid installing a one-pin connector, then some form of breakable splice was called for. For the three weeks I spent on the Cessna 310/320 assembly line, I installed a bucket-full of "wrist-locks" . . . Emacs! In other venues, the knife-splice was favored . . . Emacs! Both technologies were covered with an insulating sleeve secured in the center with a tie of string. Today, one might use heat-shrink. Both technologies offer a tug-resistant splice with good integrity. When I left Hawker-Beech, these technologies had been replaced in production for many years. Powers that be favored a line of one-pin connectors. These were plastic housings with a double-ended female connector molded in. A splice as achieved by crimping the appropriate male pin on both wires and seating them into the double-female housing. It was fairly compact, used tools and pins commonly used all over the airplane . . . and could be opened by simply extracting one of the two pins with the appropriate tool. MUCH more expensive for materials . . . a toss-up I think for labor . . . but it IS the latest and greatest. In the mean time, there's nothing 'wrong' with knife- spices or wrist-locks if they meet your design goals.

Actually, John, that is not really clear in the America we live in today. Hopefully, after this election, perhaps it will become more clear.

Day VFR only, a comm, a transponder, a few miscellaneous widgets like boost pump, smoke pump, engine monitor, a couple of solenoid valves, and the engine is the venerable M14P which is an air start motor. So the battery is also correspondingly small, and recharged by the B&C SK10 alternator. The traditional basic electrical schematic has an avionics master but I'm discarding this because, well, I just can't see why it is needed at all for this setup. Any issues there? This diagram is also drawn with no battery contactor, but a main battery circuit breaker instead, and the master switch is 14AWG wire in one side and out the other to the bus, I believe. How does this rate compared to using a battery contactor instead? I do recall Bob talking of this being a bit of an unconventional layout (regarding a B&C wiring diagram a while back). Would it be better to specify a battery contactor in a conventional arrangement, or for this system would it not matter too much?

The unit is a few years old and he has just recently taken his first flight. The fuel pressure has never functioned. The fuel pressure sender is a JPI 3060-17, which is 5-32 PSI, 2 wire resistive, for fuel injected engines (he has an IO-360). He has confirmed wiring continuity and tested for shorts. The pressure sender has been replaced with a new one. He called JPI/Vision Microsystems but they were quite uninterested and unhelpful :-( What they did tell him is that while the manual indicates connections to P5 pins 4 through 7, this particular sensor should be connected between P5-7 (fuel pressure ground) and P5-8 (unlabelled in the manual). Configuration is also necessary. Section 40.3 has five choices. I watched him try each one. The result is that the pressure immediately rises to the top of the scale and then the readout is replaced with Err. Has anyone had success making this work ? Which pins did you wire the sensor to ? Did you add a pull up resistor, or ground one of the leads ? Which configuration option worked ? Any ideas will be appreciated.
