Great response Bob, thank you. That certainly drives the point home!

I understand why a fusible link is specified in line with the 5A breaker for alternator field feed. The breaker is designed to trip when the regulator grounds the feed in case of bus overvoltage. An ...

Thanks Bob. Prior to your response, I moved the battery bus and E-bus relay south of the firewall on my schematic. I think I like that better anyway. Roughly the same number of wires transiting the ...

I requested the spec sheet for the S704-1 relay from B&C, and it is a Tyco T9A with an operating temp limit of 85C (185F). This seems a bit low for mounting in the engine compartment on the firew ...

I should have posted some notes along with the schematic. Most have been covered. One that has not involves the E-bus feed diode. I selected a Power Schottky from Ixys. Cheapest outlet I found was ...

Noah,
Here are some suggestions for weight savings.
12AWG (or maybe 14) is big enough for the aux alternator and E-Bus.
Have you done a load analysis on the E-Bus, adding the actual amperage of ind ...

Noah,

I don't see any wiring errors.

I am planning to use the same architecture but with a couple of different details you might consider.

1. I am going to eliminate the two shunts and run bo ...

Noah,

Thanks for posting your schematic. As you know, I'm doing something similar because Z-13, with an SD-8, does not meet the needs of my all electric plane with high Ebus loads. I opted for a 4 ...

Greetings-

I am requesting comments on the following dual alternator single battery schematic using Plane Power 60A and B&C SD-20 alternators using an external SB-1B regulator.

Two questions regarding Z-8.

1. I assume this "new" Z-8 is different from the Z-8 published in 1999 in your document "All Electric Airplane on a Budget" at:

Bob, I appreciate the response, but from a technical perspective, it doesn't give me much to go on.

Let me try my question from a different angle.

I prefer Z-13 over Z-12 because of the salien ...

I purchased an SD-20 auxiliary alternator after reading AEC a couple of years ago, and had been planning a Z-13/20. Subsequent to this purchase and installation on my engine, Bob has indicated on num ...

Thanks for the responses guys.

Bob, just curious why you started a new thread rather than respond to my original post, keeping this discussion all in one thread? One result of this action is tha ...

Just finished reading AEC and new to forum, building RV-7. I have 3 questions related to forum administration:

1. Is there a way for the site administrator to enable previewing of threads from the ...
