This is a battery contatctor with a dual battery voltage sensor and control module added on. From the literature this appears to be a simple solution to automatic isolation and control of a dual battery, single alternator electrical system. Take a look at the lit. and comment. Upon first blush this appears to supplant the dual contactor with a single contactor and a voltage sense and control circuit. http://www.colehersee.com/pdf/hot_feed/D-617_SmartBatteryIso.pdf Chris Stone RV-8 Newberg, OR ________________________________ Message 4 _____________________________________ Time: 11:43:49 AM PST US Subject: AeroElectric-List: Switchology Question From: "logansc" Guys: I have a newly finished Rocket, wired IAW Z13-8. My system has a big battery, a 60 amp alternator (Plane Power) and an SD-8 backup. I have not tested the SD-8 yet and was wondering if there is a protocol for that, that I should observe. I have a three position main DC Master switch (off, Batt, on) and no avionics master (I prefer turning each on and off individually). I also have separate E-bus Alt Feed and Aux Alternator on-off switches. I plan to test my SD-8 on the ground with all my avionics off except my engine monitor (which has my volt and ammeters) to see if it is wired correctly and shows Aux Alternator output. Should I start on the main system, turn on the engine monitor, and then switch the main to Batt, and then the E-bus on, and then the Aux Alt on, and then the Batt off? If that is all correct, then airborne if I lose or shut down the main alternator, is the sequence the same? Haven't got the diagrams with me at the moment and I'm trying to write a procedure. Any help would be appreciated. Thanks, Lee...

Photometric units contain plenty of traps for the unwary. BTW: "Cree Achieves 186 Lumens per Watt from a High-Power LED High-performance chip and R&D package combine for record-setting efficacy" Amazing. -------- Eric M.

I have one on my 1976 GMC motor home. It is installed across the factory installed isolator (diode). The difference that I see, is that the combiner we're using on our motor homes works both directions (i.e. chassis -> house and house -> chassis). What this means is that if we are on the road it charges the house battery(s) and if we are docked with shore power (or the generator running), the chassis battery will also be charged. It works as advertised and I'm happy with it. I have the Cobiner 100 (good for a 100 amp alternator). It lists at $79.95 and on sale for $59.95 which is what I paid.

It appears also that you can force the contactor closed for cranking assist. I.e. just like a plain vanilla aux battery contactor with an aux battery management module built in. You'd still have a manually switched battery master contactor.

You won't see any output from the SD-8 without being well above 2000 rpm. So you can craft any procedure that makes sense to you.
