One ground and one feed. The other two are for data transfer. My recollection is that they are crossed, that is, the power feed A+ is opposite the Ground, etc. For my Garmin 295, the pin out directions are in the addendum section of the manual. What Garmin do you have?

The only draw back is if the passive (power off, not active) noise canceling of the headset is poor like the Bose X in which case you have very little effect from the headset without power for the active system. If the headset is able to control the background noise with the power off, then that is what will happen if you should lose power to your headset.

I've convinced myself that the Carling switches we have (from B&C) are suitable after reading Bob's "Switch Rating" article. However, I'm curious about the physics... Is there really 250 V built up in that dual CDI just waiting for a path to ground? I assume that there is resistance in series to limit the current to 0.5 A when the ignition system is shorted. Would more resistance in series with the "kill" switch act to increase the time constant of the shorted ignition circuit (assuming it looks like an RC circuit) thus leading to a longer "bleed" of energy from the CDI capacitors... and perhaps a delayed shutdown? Can anyone describe a "typical" time history of voltage and current across the switch contacts for a "kill" event? Thanks for entertaining such random thoughts!

Now I need to figure out what goes to what. My particular used Turn and Bank was made by Precision Aero Instruments, but my guess is that a three pin hook-up must be close to universal? Looking in to the plug on the back of the instrument there is a "key" at about 11:00 to orient the plug with pins at about 2:00, 5:00 and 9:00. I'm guessing one of these pins is ground and one is 12 volt +? Would the third be for a light, if present?

Our Europa has a Rotax 914 and want to use a ND alternator on the vacuum pad as primary alternator with a LR3C regulator and use the internal generator as Aux alternator. The battery will be between 12 and 18 amps located aft of the motor and Main-Bus and E-Bus by 7 feet (~ 14 feet of wire) run will be using #4 wire. 1) Will the LR3C be happy if I connect the #6 Bus to my Main Bus, or should it really go closer to the battery? 2) Will the LR3C be happy if I connect the #3 OV sense wire to my Main Bus, or should it really go closer to the battery? 3) Rotax install manual wants difference between terminal C of the regulator and the battery to be less than .2V, is this achievable with 12 feet of wire and a max load of 30 amps? What would happen if more than .2V difference? 4)Rotax Install manual states" never sever connection between terminal C and +B of regulator e.g. by removal of fuse" Z-16 which is designed for only use of internal Rotax generator looks like it disconnects C and +B, Z-13/8 which uses a SD8 as a aux alternator only makes or breaks the output of SD-8. When using Rotax internal generator as Aux on Z-13/8 do I want to follow Z-16 and sever, or follow Z-13/8 and leave C and +B connected and only make and break output? 5) Rotax install manual recommends a 30 amp slow blow fuse on output of regulator, is a 16AWG Fuselink as used in Z-16 equivalent to a 30 amp slow blow fuse? 6) On Z-13/7 E-Bus has a 20 AWG Fuse-link,16AWG wire, switch and 7 amp fuse: Z-32 Heavy Duty E-Bus Feed bumps up wire to 14AWG, a 10 amp fuse and a relay instead of a switch a) For the 3 additional amp fuse, why did a relay replace switch? b) Why was Fuse-link dropped? Thx. Sincerely Ron Parigoris
