Sorry, but there is no Ground but The Ground in a composite aircraft! That is to say, the negative side of the battery. >From that it is simply a matter of practice in minimizing the resistance back to that point. Noise is created when changing current flows move across a resistance, and those changes in current occur at high enough frequency to radiate to adjacent conductors. Prevention of noise therefore seeks to minimize resistance to ground, and improve shielding.

Has anybody done Mod 60. The Europa Fuel sender fit, I have looked at it and its not simple as the sender unit is placed in the headrest Pocket locker location and requires new hole cutting in the tank. I would like to place the sender in the existing location of my sender which is in the middle of the tank, so as to use and modify my existing hole. This would also be dependent on the length of the sender to touch the bottom of the middle of the tank with a setting of Zero ,this would leave a safety factor or the fuel in the saddle, which I think might be about 8 ltrs ? So if anyone has fitted Mod 60, would my way be possible, Thanks.

Reducing impedance in ground paths is the prime consideration. Short, fat and tight! No special distinct classes are required. At least no voodoo is required below UHF. I pulled the trig y91 install manual off their site. Look at the wiring diagram on page 52. Observe: 1)that all power and signal grounds are tied together and to aircraft ground. Indeed, in the text, it says they only provide 5 ground pins yet 9 are required, so tie them all together (section 5.6.12 on p22)! 2) Next, direct your attention to the RF coax connector. Note that there is only the center conductor shown. That is because the coax ground is tied directly to the chassis/case ground. The signal grounds go to the same place as the chassis (section 5.6.11)! -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=432433#432433 ________________________________ Message 7 _____________________________________ Time: 04:40:06 PM PST US From: david park Subject: Re: Europa-List: Mod 60 Europa Fuel Gauge I used the bendable probes in to each side from the top inboard of the headrests.
