Joe,

You mangled my schematic and made it better. I had the diode in the wrong spot. In you configuration, in the top switch position, the engine keeps running if the battery bus dies, runs off of ...

Lightspeed Ignition. Klaus recommends that #1 be tied to the battery - it is.
#2 can be tied to the main or essential bus. This circuit is only for #2.

Thought here is that it's a single switch (l ...

Have a pretty solid electric system derived from the Z diagrams on my EZ.
Going to dual electronic ignition and have high confidence in 2 alternators and a battery, but want a standby "get me do ...

Stencils!Bob, trying to accurately coral the mosquito poop on more than one board will drive you bat$#!+ crazy. I've bought stencils for doing boards and I use an old hotel key - one or two swipes ...

I am setting up the regulator and components from Z25L for a self exciting SD-8 to support backup power for my second ignition and backup power for the aircraft E-Bus.

One option is to screw this ...

Thanks! Getting a new one on the way ASAP.

Old master relay in my Long EZ - it's pulling about 2.3 amps - just the relay itself - sounds like it's way high. Any recommendations for a low current replacement?

What's the typical draw for one ...

Bob,

Great find on the LR3 voltage sense. I need to double check where I have that installed right now.

Ignitions: No real monkey motion... primary is dual feed (battery and main alternator.) Ma ...

Bob, and the rest of the AeroElectric crew,

Thank you for all of the guidance. About to install this fun in the next week or two - just need to take a couple days away from work and a long weekend. ...

Bob, et al.,

Finally have all of the parts and pieces for the upgrade - new panel wiring is almost complete and ready to haul out to the airport for the install. Decided to bite the bullet and do t ...

Much less expensive and higher accuracy component - newer vers ...

This is continuing to be a really good journey.

My philosophy is shifting from how I've flown for years based on what I'm learning here towards what's in Z101. I am likely going to go dual battery ...

Bob,

Thanks! I've got other builders watching our learnings here closely so... Smile

I added the appropriate loads to where they need to go.
Main bus: (breaker size)
Pitot: 20A
Lighting: 10A

David,
Yes - looked at the Z101 - wasn't in my old book - or at least I missed it. Modifying it to use the rectifier to support the E bus.

Bob,
The failure that comes to mind is the master switch ...

Bob,

The SD-8 concerns me 'cause if I lose the electric system, I lose the engine which means I won't get enough power out of the SD8 (low RPM) to run the ignitions to restart.

Got an option th ...

Charlie,

Thanks! It's coming along. I am more than willing to share the design on a limited basis (my wife and I were talking about this topic last night, but exploring the right options to protect ...

So, this came up in another thread and I was asked to share... Plan is to write it up for Sport Aviation, but this group has been such a help over the years, and such a knowledge-base for both my fun ...

Charlie,

Starting a new topic on the engine monitor...

Bob,

It's an O-235 C1C with 8.5:1 pistons and dual Lightspeed Plasma III's. Carbureted... No vacuum system or mags. She's flying right now (with 1 mag, 1 Plasma III), but our ramp shuts down for 10 ...

Drew this up in upverter.com... Not the best for schematics, but I think this gets the idea across. Pinouts of devices aren't defined here. Fuse Blocks are the above recommended fuse blocks.
