I am using a fuel gauge that is connected to capacitance type probes. When the engine is running, (503 DCDI) the fuel gauge jumps around like crazy. After much testing and trouble shooting, I believe the problem is related to the fuel sender wires running near the ignition kill wires and/or the tach wire. When I move part of the fuel sender wires a few inches away, the problem improves. I'm really not wanting to move the sender wires to the other side of the airplane to give more space between the different wire types. Before I do this (since it would be a lot of work for a fix that's not 100% guaranteed), is there a quick and easy way to shield the fuel sender wires? Would this even work? Any help from the electricians in the group would be appreciated. Michael,I used shielded two conductor 18 Belden for kill switch wires on my 503 powered Loehle, and 2SI powered Mk-3.Only connect the engine side shield wire to ground and trim the switch end shield wire even with the jacket.This should clear up your noise.Denny Rowe ________________________________ Message 3 _____________________________________ Time: 03:42:26 AM PST US Subject: Kolb-List: Re: Oshkosh 2008 From: "icrashrc" I'll be there Thursday and Friday. -------- Scott www.ill-EagleAviation.com do not archive Read this topic online here: http://forums.matronics.com/viewtopic.php?p=193748#193748 ________________________________ Message 4 _____________________________________ Time: 03:44:12 AM PST US From: "pj.ladd" Subject: Re: Kolb-List: Re: Flying into Dust Devils Well we were excited to see it run up for the first time.>> Hi Will, Indeed I do.

I have a suggestion based on a problem we encountered on our Allegro. We used a couple SS clamps similar to those shown in your photo, to help stabilize the muffler which had a tendency to vibrate a lot and crack. Inadvertently, we had one of the clamps making a relatively sharp bend (like your 90 degree bend at the bottom of your battery) where the screw thread slits were located. With the higher stresses at the corner and the weaker part of the clamp, it broke. When we installed the replacement we positioned it so that the weak part was not at the higher stress area and had no problems since then.

It's just cleaner and not that expensive to do. I had all my cables "machine" swaged this way ( elevator, rudder and tail wires) by a guy near Aircraft Spruce in Griffin Ga. He supplies the cables and fittings. He does need to know the length from "hole to hole" on the attachment points and they are only adjustable about an inch. There is only a turnbuckle on one end so you better know the measurements if he's not local. I'm sure there are people like him all over the country. ________________________________ Message 7 _____________________________________ Time: 06:06:57 AM PST US From: "Jim Kmet" Subject: Kolb-List: Painting Lexan Hi all, A few of you have painted Borders around your Window & Door frames, My question is what Kind of paint works well on the Lexan we have on our K olbs??

I was wondering if shielding the fuel sender wire would work instead of shielding the ignition wire and if so, what can be purchased to shield it? I don't want to mess with any other wires since I don't have any problems with radio noise. I just need a little distance between the sender wire and the other wires that are bundled and running down the side of the frame to the instrument panel. The tach wire might be the culprit as well so I would really just like to shield the sender wire without replacing any wires or moving anything around. Is there shielding that can be purchased (or made) and slipped over the existing wire? The wire currently runs along with all the other wires in a bundle which is doesn't like, but this makes for a cleaner installation than having wires running up both sides of the fuselage. If the shielding won't work, then this will be my next step. Moving half the wire away from the bundle by about 2 inches made the problem improve by at least 40%. The capacitance system must be very sensitive to other electrical fields. ________________________________ Message 11 ____________________________________ Time: 07:38:55 AM PST US From: Russ RKIPhoto Subject: Re: Kolb-List: New Battery Holder in FireFly Jack NICE job on the new battery holder.

It should be noted that most, if not all rg-58 has a solid center conductor. If it's installed where it doesn't move at all, it will probably outlast you & the plane. However, if you're plugging & unplugging from a hand-held & hang the dipole end so it can flex & move as the plane moves, you might have problems with the center conductor either breaking or pushing its way through the foam center insulation & touching the shield. There are other 50 ohm coaxes that have a stranded center conductor so they are more flexible.
