Dick, I will have two switches. The plan is to use the DPST to switch legs of 6-7A and 2A. One switch is a Honeywell AML 34, rated at 125v/15a @ 60% power factor. The back-up is a Honeywell AML 31, 125v/10a @ 60% In a similar chart for another switch, Honeywell specifies "Resistive", along with % power factor so I'm assuming that the %power factor is for inductive loads. The 6-7 A load is for electronic fuel injectors which I believe are solenoids and hence, inductive loads. Joe, I didn't quite follow how the loads on the switch legs are additive. Each pole/switch is separate from the other in the switch and are fed from fuses on separate buses.

As someone else mentioned, you can make your own with either solder or crimp DB15 connectors by just including a second wire connected to each DB15 interconnect wire.

Another person told me they'd expect noise if the P-leads are in the same bundle to the panel. That's how I've got them. But I don't have any audio system hooked up yet. Those wires would cross the P-leads or at a right angle. -------- Dan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=305689#305689 ________________________________ Message 16 ____________________________________ Time: 08:19:36 PM PST US From: "Robert L.

It's called a >Break Out Box. Yeah, I've got a fist full of those that have proven handy in my business for over 50 years. When you're working with low current D-sub signals, here's a little trick . . . http://aeroelectric.com/Pictures/Tools/Test_Equipment/Quck_n_Dirty_Breakout.jpg A piece of ribbon cable and some munch-on connectors can be assemble in a variety of useful combinations. A M-F patch cable of appropriate length can be 'enhanced' with a female connector either between the ends . . . or on a "flying tail". Last time I built one of these was to look at some signals on a black-box buried about 3' away from anyplace I could get access to in flight. I took a 4' piece of ribbon cable and munched the M-F pair on one end about 4" apart. On the other end, I put a female connector to serve as an array of tiny "pin jacks" where ir proved easy to eavesdrop on what was happening at the other end of the cable. If I were in better shape for being unpacked and sorted out, I could send you the break-out adapter shown in the picture. If you can't get ribbon cable and connectors locally, a friend of mine in Wichita could assemble one for you from inventory (Lloyd's Electronics) and mail it to you. The whole thing goes together in about 5 minutes for about five dollars.
