My contactor looks like this: http://www.aeroelectric.com/Pictures/Contactors/s701-1.jpg What would be the proper way to handle the diode and jumper wire?

You need to reverse everything in the picture. Diode flips over, jumper wire moves to the right-hand terminals, battery fat-wire now goes on right fat terminal, system fat-wire goes on left fat terminal. Alternatively, you can simply turn the contactor around on its mounting bolts and leave it wired as shown in the photo.

Sounds like you're using way too much heat. See if you can put your hands on a "micro torch" of some variety. http://aeroelectric.com/Pictures/Tools/Soldering/Gas_Tools/ Alternatively, turn your pipe-blaster propane shop torch down to the smallest possible stable flame. The inner blue cone should be about 1/4" long max. The wire strands inside the terminal need to be TIGHT. Heat conducts across strands by virtue of (1) contact and (2) immersion in molten solder. Make sure the strands are well-wedged to improve upon condition (1) so that condition (2) progresses nicely as well. Start by heating the back side of the terminal flag and touch solder to the corner between the front side of the flag and the cut ends of the wire. As soon as the solder melts, it will begin to pick up the wire strands. Walk around the terminal barrel with the heat while feeding solder into the strands adjacent to the inside surface of the barrel. The heat in the joint will be climbing all the time and by the time you get all around the barrel, you will see solder wicking into the strands pretty much all around. Feed a little more solder into the stranding until all the ends are captured. If you see ANY solder at the other end of the barrel, you've gotten it too hot and/or put in too much solder. From the time the solder first flows until the joint is done is less than one minute. The longer you take, the hotter things get, the less likely it is that you can maintain control over the flow of solder.

Thanks, Jeff --------------------------------------------------------------------- A friend of mine is flying a Citabria. It is quite new, but suffered in a crash. I was completely rebuilt/restored and is now again a beautiful airplane. It has one snag. Perhaps folks on the list have some ideas. The symptom is that sometimes radio reception is unreadable. Scratchy static overwhelms the voice audio. It is most obvious when within 5 miles of the control tower, since it is necessary to ask the controller to repeat multiple times. Other times, aircraft from over 100 miles away are heard on common frequencies, or the controller is clear, so sometimes the receive works very well. Transmit is believed okay. The tower never complains about transmissions, but this has never really been checked over greater distances than 10 miles. The radio is a new Garmin, which was swapped for a few days with an identical model, which exhibited the same symptoms. Consultation with the factory has yielded little. Mechanics have checked phyical connections and continuity, and cut the fabric under the antenna so the ground doesn't rely entirely on the screws. He has tried different headsets. The ground plane is a piece of aluminum about 6" wide and 15" long on the back of the aircraft where the ELT antenna is typically installed. There are about 8 wires, tied together and attached to the ground plane about 4" ahead of the antenna, and these wires wrap down around the fuselage to extend the ground plane. The ground plane is also electrically connected to the steel fuselage tubing. This is all per factory instructions. There are no adjacent antennas, and this antenna is at least 4 feet ahead of the tail. Reportedly, a VSWR test at the antenna gave a poor result, but I was not involved in the test and I am not sure about the reliability of the equipment or the person doing the test. The antenna is a new Comant, with COM and GPS. Most of the things I can think of being wrong would likely affect transmit more than receive and not produce static. I am currently thinking that perhaps the radio, antenna etc. are actually fine, but are intermittently being interfered with. I have suggested to the owner that when the problem occurs, he try powering off the new PS Eng audio/intercom, which then gives him a direct connection to the radio. I also suggested he power off the transponder. If that fails to help, I have loaned him a new antenna (I will be a while building yet) to try. If that doesn't help ... ??? Does anyone have any other ideas that should be looked into ? Thanks !

Check the wiring again. I've experiences similar problems when the plugs at the back of the tray don't fully engage as the radio is seated. Scratchy audio could result from dirty pins/sockets, mismatched pins/sockets, bad crimps, broken wires in intermitent contact, etc. It could also reside in the audio panel / intercom. If the antenna is the correct length, the bad VSWR could result from impropper mating at the connector, bad crimps, dirty connectors, poor ground, etc. neal ================ Does no one have any comments to offer on this ?

Start by replacing the antenna coax with a known good cable. It may have been damaged in the crash and have an intermittent center conductor. When transmitting there is enough power to punch through to the tower even with the VSWR mismatch, but reception is extremely low power and subject to signal degradation. Just a guess...

About the only time you might want to consider orientation is in the unlikely event that the solenoid return spring should fail. It would be nice, then, if you could have gravity (or centrifugal force) working for you to open the contacts.

It >would be nice, then, if you could have gravity (or centrifugal >force) working for you to open the contacts. I've never seen one fail. They're very lightly stressed. I've seen them corrode . . . but then after water enters the device, worrying about spring corrosion is the least of concerns. There's a lot of mythology circulating around about "proper orientation of contactors with respect to g-loads" . . . This has been debunked several times and can be reviewed in the archives.
