Even tough learning new skills is always fun and educative, I would keep a DIY approach on last resort, First, they seem to be readily available from B&C, Second, its for a friend project, and I have no clue about elctronics etc, Id rather spend some time on my on electric wiring, Thank, Ill try b&c once again, and then task my father on the subject, hes a retired electronic engineer, Im sure hell understand all those little drawings -------- 2020 contribution paid Read this topic online here: http://forums.matronics.com/viewtopic.php?p=500891#500891 ________________________________ Message 2 _____________________________________ Time: 03:17:52 PM PST US Subject: Re: AeroElectric-List: Re: Peer review, Z16 Rotax engine, Ducati Regulator From: GTH Le 08/03/2021 22:00, velletazjp a crit: > > Thanks for the details. > > Even tough learning new skills is always fun and educative, I would keep a DIY approach on last resort, > > First, they seem to be readily available from B&C, > Second, its for a friend project, and I have no clue about elctronics etc, Id rather spend some time on my on electric wiring, > > > Thank, > Ill try b&c once again, and then task my father on the subject, hes a retired electronic engineer, Im sure hell understand all those little drawings > Hi JP and all, Why not ask B and C if they would accept to just sell the little module ?

The sense wire will be about 5' long. 1. I'm thinking of using an 18AWG wire for the sense wire. I don't want any voltage loss on this sense circuit. 2. Is there any particular need to insert a fuse? It would call for a 10A fuse. If I need one, I'd probably use an inline automobile fuse but I haven't decided to add a fuse or not. Your thought?

My intention is to put a switch in the line of at least one of the wires to the G terminal on the Silent Hektik Voltage regulator. 1. Switch both wires or only one? 2. I'm not sure of the size of the existing yellow wire, but am thinking of using a 16AWG wire. It will be about 5' long and go from the VR on the front of the firewall to the instrument panel and back to the VR. It is my plan to leave the CB engaged and normally leave the internal generator off by opening the switch in the yellow wire. If the 40A alternator goes bad I'd engage the internal generator.

It only carries signal current (milliamps). Only one wire is required from terminal C to a switch to a fuse to the main power bus. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=500899#500899 ________________________________ Message 6 _____________________________________ Time: 08:10:47 PM PST US Subject: AeroElectric-List: Re: Rotax 912ULS External Alt Sense Wire From: "user9253" The only way to lose voltage is for current to flow. A sense wire that carries very little current will have very little voltage drop. A 25 amp circuit breaker is too big to protect a small gauge wire. So protect the sense wire with a fuse. Wires subject to engine vibration are more likely to short out than in other places in an airplane. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=500901#500901 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
