Kelly, good point about the alternating pumps. Of course normally both pumps will be operating for takeoff and landing. The bus will be sized for both pumps to be operating but if the main alternator ...

My calculations are definitely on the conservative side. I distributed the loads such that I could fly on the Aux bus and Engine busses alone in IMC if I were to lose the primary alternator or otherwi ...

I don't see a problem with that segment. The portion forward of the firewall will be protected by an ANL fuse. I don't think there's a way around having a smaller always hot wire that runs from the ba ...

"second large conductor", "decent loads", "considerable weight"
are not quantified. The best decisions are made with calculated
data. What are the loads on conduc ...

Thanks for the comments Kelly. For starters while I am planning for a single battery, I am definitely installing dual alternators. I believe a second battery would be of marginal benefit given the cha ...

I'm in Belleville, 2 hours from Toronto.

The hot battery bus itself is only about 0.5 amps for a few overhead lights. The issue is that the Z-101 schematic has the ability to power the aux and engi ...

Hey Jeff, I am in Canada. That is my plan for the loads downstream of the battery contactor. But the Z-101 schematic also has several loads connected to the battery side of the battery contactor (hot ...

Good evening all,

I'm working away on an electrical architecture for my RV-10 based on Z-101B. I haven't started to install the system yet but I have a question about how I will actually install th ...

Thanks to you both for the quick feedback. I'll include the jumper from the contactor "I" terminal to the starter with the extra diode.

You are correct that B&C no longer sells the cr ...

Good afternoon,

I'm working on a schematic for my RV-10 based on the Z-101 architecture and have come up with a couple questions about contactors...

First, about the starter contactor. The Z-101 ...
