Matt,
Thanks Joe, What happens if the Aux alternator is turned on while under normal operations and both alternators are feeding the electrical system at one time?
I do not think that anything will ...

Matt,
Bob's and B&C's drawings do not conflict. They are different. There are many different ways to wire an aircraft. I suggest that you use one of Bob's drawings because his are for the whol ...

Thank you Vern, I appreciate your responding. I did not know the relay was such an unreliable device. I really do not want to spend $150 to test some LED lights (I am going to have more than 4). None ...

I was not trying to imply that one was incorrect, I just do not understand the purpose of the diode in that application and whether it is necessary or not. B&C support was unable to tell me what i ...

To answer the question as to why I would want an E-Bus feed indicator light there are a few reasons. Several VAF members have mentioned flying with the ebus switch closed under normal operations since ...

Would you guys be so kind as to tell me if the attach wiring diagram looks like it will work? I just need a simple push to test circuit for a few LED's I have. Thanks.

Bob,

Thanks for the response, but what about my question #1? should I do the diode between the common and coil or just a standard jumper? I also notice on the Z25L pdf that you linked to you have a ...

1. Am I correct that the S704-1 relay used for the backup alternator is wired to the regulator with the N.O. lead?

2. Can I use the N.C. lead for an "Aux Alt Offline" light? I assume thi ...

Bob,

B&C recommended I ask you these questions because they did not know the answer for them. As you may know, they have a document called the 504-500 linked here http://www.bandc.biz/pdfs/504 ...

Okay, I understand about the necessity for the switch otherwise you could never shut off power to the e-bus.

But I am still confused about if there would be a problem if it were inadvertently swit ...

I am working with Bob's Z-13/8 and I am confused about the wire size between the main -> e-bus. In the drawing he has it as 20AWG. This seems way to small to me to power the e-bus.

In my scenar ...

What happens if your E-Bus feed switch is turned on during normal operations? In this scenario it looks like power would be coming in from two directions according to Z-13/8... If that is not a proble ...

Jeff,

I did end up moving the lighting off the battery bus and onto the endurance bus. I also moved the landing light and flaps to the main bus as per your suggestions. I was thinking in an electri ...

Peter (and others),

It has taken me a while to address the items in your post. Thanks for reviewing my load analysis so thoroughly I appreciate it… I ended up moving the compass light completely ...

Would you guys be so kind as to review my Load Analysis worksheet and tell me if you see anything that looks incorrect or have recommendations to make it better? I have spent quite a bit of time on th ...

I am a bit confused and thought I would ask here for clarification. I am trying to design my electrical system from Z-13/8. It looks as though there is a direct route for the power direct to the batt ...

What is the latest revision of Z drawing 13/8? I found one Rev. Q which I know is old, and another Rev. R that is dated 11/18/10 but it is watermarked with the word "PRELIMINARY". Is that th ...
