I really like the set-up, but took the switch guard off as they looked too out-of-scale for the panel. I used Eaton switches MS35058-22/8801K22 for the mag/EI and MS35058-30/881K17 for the start switch. The panel layout has them in a horizontal row with, from the left, the Lmag, EI, start, alt, bat. These are located separate from the rest of the switches. I used all 88 series switches to keep the look uniform. If you would like a pic, let me know.

I ended up using nutserts in the panel. I was afraid that the nutserts would make for an unsightly installation since their slightly proud face will leave a tiny gap between the control head flange and the panel, but with them both being black the only way you can notice is if you back light the installation.

Having just installed a 450 last weekend, I can assure you that the AK-450 does in fact have a battery in the remote unit.

Thanks I don't have a circuit to publish . . . there have been numerous approaches to delayed annunciation of a uncertain output from many level sensing switches at the operation level. While working another task . . . http://www.aeroelectric.com/Catalog/AEC/9011/9011-700-1.pdf . . . it just came to mind that without changing any of the hardware, this product could be re-programmed to do the flicker-filtering task but with more agility than commercial off the shelf timer options. We haven't decided to tackle that task yet. We're mulling over a whole new approach to low liquid level sensing combined with perhaps some programmable fuel management options. I was just putting a dipstick into the marketplace on the rudimentary flicker-filter as a stand-alone item.

One of the wire pairs from the engine compartment is the 5 amp breaker switch to the field terminal on the BC20 alternator. I recall that Bob has suggested a mean current draw of 4 amps max for the gold plated 0.040 DB style pins and sockets, which have the part number S604 on the B&C site. Could I use a pair of these to carry the current through the field circuit breaker and switch? If the overvoltage crowbar on the LR-3 regulator shorts the field, there will be a momentary current draw of much larger magnitude. The data sheets for this series of breakers at 5 amps suggests 50 milliohms internal resistance, and if I use 12 feet of 20 gauge wire, this will add 120 milliohms to the circuit. I don't know the internal resistance of the crowbar. If set to zero, this leaves 170 milliohms plus the contact resistance of two series pairs of the pin and socket. I have not measured this resistance, but the Tyco (Amp) site suggests 10 millohm maximum. After doing some reading, I find that the CPC series with "size 20" pins and sockets is rated at a single circuit of 8.34 amps continuous with a 30 degree C rise in temperature. The breaker will open in 0.2 to 0.6 sec at 1000% load. When the crowbar fires, the instantaneous current before heating is 16 volts/0.18 ohms, or 89 amps. The bimetal thermal breaker should raise its electrical resistance much faster than the wiring because it is enclosed. I'm not sure. The convenience of routing all wires through this one or two CPC connector set is attractive, but I could run the wires through a grommet in the panel, directly to the breaker. It is harder to take apart this way, but at this point, I have convinced myself that the direct route to the Fast-On tab on the breaker is the best way. Having spent several hours researching this, I thought I'd share it with the list. The two Tyco PDF documents of interest are: instruction sheet 408-7593 and 108-10024-3 on the web site.

I got a little confused looking at the pinouts on the connector and there wasn't any elaboration about it in the rest of the manual. But I figured the answers could be found on the list. Where would I be without it!

From: --> AeroElectric-List message posted by: Studying Rotax 914 schematic, the main fuel pump is wired to the B+ of the regulator. It appears if you open the alternator output switch, they expect the alternator could run the fuel pump with no battery in circuit??? They do have a 22000mF capacitor from B+ to ground. OK another question comes to mind. On Bobs Z-8 which uses a SD-8, if the output relay was opened (not connected to battery or Buss) and you connected a 3 amp fuel pump motor to the red output of the regulator would it run and be happy for an emergency? Called for on Z-8 is a 20000 to 50000mF capacitor connected to red output. Thx.

I purchased Van=92s harness, figured it would give me a head start but I find that I question some of the choices made, namely the size of the Alternator output. Am planning on a 40amp alternator, aft mounted battery. Vans has chosen #8 awg =96 if I look at BK=92s figure 8-4 on temp rise vs wire size, I read 21 amps for a 10=B0C rise and 40amps for 35=B0C rise. Since I shall be running a 40amp alternator I figure that 35=B0C is too much since the wire will be bundled with others =96 I=92d be better of with a larger wire. If I put a #6, temperature rise at 40amps is somewhere around 20=B0C. My question to you guys who have been there : should I go for #8 or # 6?
