I have a copy of TurboCad v9 and have used Turbocad for years (it is cheap and very powerful), but the ExpressPCB is much more suited to doing wiring schematics. Many symbols are built in but they are mostly for printed circuits. However, it is very easy to develop custom symbols and put them in the "favorite" library.

I think you're dead-on correct. First, a b-lead contactor needs to be a real contactor, i.e. double make-break contacts in series. This greatly improves the ability of the device to open a rapidly rising source voltage when the contacts open. As to the boss-hog relays offered in the automotive world with impressive ratings, I agree that their usefulness is limited at the higher ratings and there are other issues like quality of the fast-on joint that makes them problematic for use at those ratings. Even though the fuse blocks are RATED at up to 30A per branch, I prefer to de-rate them to 15A. Any larger load should step up in robustness like the Maxi Fuse in-line holders. Degradation due to electrical heating is an I(squared)*R effect. Cutting currents to 1/2 drops stress to 1/4. I have no doubt that ALL of the manufacturers of these products have crafted ratings in good faith . . . I wouldn't suggest that anyone is being dishonest. But we do know that the highest stresses on most light aircraft electrics are environmental . . . they degrade with age and ultimately fail electrically when mate-up forces and finishes don't carry the current any more. Hence our preoccupation with longevity for gas-tight joints, de-rated contacts and doing the best we can with the $time$ invested in parts selection and installation. I agree that there are few if any places where I would want to install the VF-7 with an intention of loading it to a high percentage of its ratings.

I want to announce my appreciation for all the comments received for the above subject. This list rocks ... when there's a need to feed, you guys step-up to the plate and hit home runs. There were well over a dozen replies with suggestions and comments. I've tried several programs and found I prefer something simple and predicable with no study time involved. Yesterday I got my patience out of storage and made a schematic for the fat wires and big users, with my paint program. The design includes two batteries, one alternator, starter, three busses and required control switches and power diodes, for an all electric RV8A. It took a bit of time but I'm happy. I will continue with Paint to create the individual circuits. Many thinks to all ...

There are superb examples of what our computer savvy cohorts can do, but I'm not one of them. Sometimes folks that have gained significant skill sets through work or other hobbies forget that these are non-trivial excercises for the rest of us. I've looked at and tinkered with much of what has been suggested on this list, but the time / effort / cost involved in mastering these tools is more than I care to invest. Hence, I've created a Paint file titled "parts", and I cut and paste what I need to make the schematics for my all-electric, IFR airplane. They are definately not as pretty as what has been offered up here, but they work quite well for my needs. My design principles may leave folks scratching their heads, but the schematics are quite self explanatory. No, I can't post them to a web site (see above), but I can fwd examples to anyone interested off-line when and as I pass through town.

Since the internal bulbs only illuminate one half of the operator (rocker), for proper convention (for on, push top of rocker) the switches can only be mounted right side up, therefore you can only engrave the top half of the operator if you want to read them at night. If you use Aircraft Engravers to purchase and engrave the operators, they should be aware of this since all of my operators had to be re-done. Line of sight is still ok with top half engraving with my extended length panel. I also had to put the switches on a dimmer circuit since they put your eyes out at night. Good luck!

If I add the E-Bus switch it goes to 12.1. With just the E-Bus switch on, my gauge shows zero volts. I have an external shunt in the position as shown in figure Z-12, between the alternator and the starter contactor. With the master switch off, I'm wondering how the gauge would get any juice?

He wants to craft a compensated signal conditioner to remove some of the uncertainty of the UMA gages that have no cold-junction compensation. I need to know the base sensitivity numbers for his instruments before I can calculate the output characteristics of the signal conditioner.

Just doesn't seem right. You lost me. Z-11 suggests you wire the voltmeter to the e-bus and the voltages you cite agree with what I'd expect for voltage readings with the alternator off. The shunt is for the ammeter which never reads anything until the alternator is running and taking battery recharge and system loads. When you say "my gauge shows zero volts" are you meaning to say "zero amps"? The ammeter will be zero until the engine is started and the alternator turned on.
