(Bruce Gray) ________________________________ Message 1 _____________________________________ Time: 01:30:49 AM PST US Subject: RV-List: Re: Ignition Problem - Troubleshooting From: "Barry Ward" I have an Electroair system and although I have not had exactly the same problem I did have one with the pick up signal that I use to provide the RPM indicator. The problem was a poor contact on the main Electroair Ignition unit. Mine which is a 1998 model had several spade connectors that connect the wires including the 12 volt power to the control unit. Probably over time (800 hours) the connector had worked loose plus some oil may have been the cause of the bad contact. I cleaned the contact and made it a tighter fit and since then there has not been a problem. I would imagine that if your system started working again after a landing which may have vibrated the wires the problem is one due to a poor contact and not a component failure. Hopefully when you have found the cause of the problem you will post the information.

We were loaded with fuel and ready to complete the second leg of our trip to Cleveland. Air from the fuel truck didn't help and it was obvious that the tire would need to be removed at the spot for repair. The good fellows at SATS Air sent a golf cart down with a mechanic and some tools to remove the wheel pants and take a closer look. Back to the hanger for more tools, a wood block, and the biggest guy in the shop, "Bubba" (not certain that's his real name, but it fits). With the mechanic at the ready by the tire, my son and me on our hands and knees (backs on the wing spar), and Bubba between us on his back (with his hands on the spar), we arched and Bubba pressed and the mechanic removed the tire in less than 30 seconds. After replacing the tube in the shop it was back to the plane. Bubba jack in place, arch and push, and wheel replaced. Now, I would like to believe that my son and I provided a lot of lift for the operation. In reality, though, Bubba likely could have lifted the plane by himself. Either way, consider the Bubba jack in a pinch for emergency repairs.

I like the tire, wears well, and with Michelins tubes, no loss of air between annuals =================================== Actually the company is Desser, in California at least. I think you can buy directly from them or many of the outlets like Chief will have Desser drop ship the product right to you. They advertise in TAP, PF and I have them listed in the Yeller Pages. I have had good luck with the Condor brand tires and use the Michelin leak stop tubes.

For this reason many certified prop/engine have indexing marks to help ensure proper(pun again) installation. RE Jacking, I made a heavy flat plate of 3/8 aluminum that is 1.5 inches wide and about 6 inches long with a u-bolt that straps it on to the tapered axel just inside of the wheel. I welded some .5" edges to the bottom side to stiffen it and provide some grip for a jack/board underneath. A couple of bricks and a five foot 2x6 underneath this plate and I can lever the wheel off the ground easily, and the plate fits into my tool kit easily. I figure I can always find either a scissors jack or a board and some bricks at any airport. If you look at the plate end on with the u-bolt it looks like this <[ and sideways it looks like this 1_____ with the one being the u-bolt that slips over the axel and is tightened as close to the brake backing plate as on can get it. I do remove the brake first, but one has to do this to get the wheel off anyways.
