Worked well. However if the plate is in a critical non-accesable location, I spring for the more expensive Click-Bond adhesive (paranoia). As an aside, Click-Bond is located at the Carson City Airport, NV, where my EAA Chapter is. We have toured the factory several time. One of the things discussed was the strength of the adhesive bond. They said that while it doesn't have great peel strength, it has good shear strength, which is required to counteract the torque of inserting the fastener.

They call for a shielded cable between the ELT and the control panel. I decided to go with the C91a ELT, but ran the shielded cable from the ELT location to the panel for future upgrade ease. I'm no expert, but I'd try the shielded control cable first.

This signal coming in on the cable is somehow interpreted as if the cockpit control had been activated. So, I wonder if there is a way to shield the cable between the ELT and the cockpit control, to reduce the amount of energy that it is picking up from COM transmissions. Also, rerouting that cable further away from the COM antenna would reduce the energy level it sees. Bob - the ACK ELT uses a length of apparently conventional telephone cable to connect the ELT to the cockpit control. Is it worth trying to replace that telephone cable with some sort of shielded cable, splicing it into a piece of telephone cable at each end so it has the correct connectors? If that was tried, where should the shield be grounded (keeping in mind this is a composite aircraft, and that the ELT enclosure and cockpit control are both made of plastic)? -- Kevin Horton RV-8 (final assemby) Ottawa, Canada http://www.kilohotel.com/rv8 SNIP ________________________________ Message 5 _____________________________________ Time: 09:30:35 AM PST US From: "Allen Fulmer" Subject: RE: AeroElectric-List: Z-19 Item Clarification What kind of Subaru Glenn?

Most Europas I have dived into (including mine) use standard unshielded telephone quad cable. My King 450 ELT does not pick up the RFI as a test button press however. The right sized toroids at the ELT end of the cable might help, Changing the length of the cable (to move it from a resonance, might help, finally, shield the cable.

One thing I noticed about the ACK installation, is that their antenna cannot be substituted for another one. It is part and parcel of the EMC filtering of the unit. According to ACK, other RF signals (e.g. comm) can be received via the ACK antenna port and falsely trigger the unit. If you did not substitute the antenna, then this would not apply.

Yes a shielded wire cable would probably do it. Personally I didn't like the telephone wire in my plane and fab'ed a 22awg cable, twisting the wires together. Before that I few with the standard phone line and did not have an RFI issue. I made the change to make it more durable.

It may be a "can't get there from here" or a "why bother" situation, but I know some of you listers love a challenge. :-) I have a B&C S8012 oil pressure switch, where the N.C. contact is wired to an oil pressure warning LED. (See http://www.bandc.biz/S8012dwg.pdf) I also have an ACS OFF-L-R-BOTH key switch for the mags (separate START button) and an S700-2-10 master switch. The issue is that I would like the oil pressure warning LED to operate only when the ACS key switch is not OFF, e.g., when it's in any of the L-R-BOTH positions. The reason is that I don't want the oil pressure warning light ON when I'm just running the panel during engine off ground ops. I plan a separate master ON nag LED, also wired through the N.C. contact. In short, I'd like to distinguish between A) master only ON, and B) master AND key switch ON. It's apparent that I need to incorporate the logic of the key switch (see Z-27 logic table) into the low oil pressure warning LED circuit somehow but I'm bamboozled as to how to do it, especially in a way that won't defeat the purpose of the mag switch(s). Of course, I'd rather not add another relay, but additional diode switching logic might be OK.

One of the toggle switches could have an extra pole which would defeat the OP light when off. Easy. I don't think the ACS key switch has any unused poles. I don't see a way to control the OP light with the key switch without adding some fail modes to the magneto operation. And needless complexity. As was mentioned by a lister a while back concerning controlling the Hobbs by means of monitoring alternator operation, a similar method could be used to control the OP warning light. With a couple of components, you could add a "defeat" circuit which would allow suppressing the OP light operation by means of a momentary push button. Turn the master on, press the OP warning "defeat" button, and the light goes out. Next time the master is cycled, the OP warning functions as expected. Finally, why are you concerned about the OP warning being on when with engine-off operations? It probably won't burn as much power as anything else in the panel.. I guess that fits into the "why bother" response category... :) Regards, Matt- > Here's a puzzle.

All points well taken. One reason to have that light OFF during engine off ground ops would be to make it more palatable to use a blinking LED. After due deliberations, I committed to the key switch some time back. As you point out, it would have been easy with mag toggles. A latching defeat switch, perhaps with an auto timeout in addition to the master cycle reset you suggest, is a possibility. Of course, the oil pressure warn is critical, and mandates a KISS architecture. No doubt, it's my inclination to complicate it that deserves a defeat switch. :-) Ron On Mon, May 5, 2008 at 1:29 PM, Matt Prather wrote: > > > > If course, you could get rid of the key switch in favor of a couple of > simple toggle switches.

I simply coiled the extra up and ty-wrapped near the ELT without difficulty. If done likewise in a composite a/c and the coil were in close proximity to the antagonist, might this cause the activation by acting like a transformer secondary amplifying com signal leakage? Is there any excess cable bundled near the com coax or antenna? Mark **************Wondering what's for Dinner Tonight? Get new twists on family favorites at AOL Food.

I have an SD-8 back up alternator on my RV-7A. I'm just curious if most people leave it running on all the time (i.e. do the two alternators fight each other ?) or just plan on turning it on if the main unit fails.
