From: "andymeyer" Bob, et al., Finally have all of the parts and pieces for the upgrade - new panel wiring is almost complete and ready to haul out to the airport for the install. Decided to bite the bullet and do the SD-8 right away - need to order this week. It will be a backup only per Z101B. Question, as the wiring diagrams I'm seeing from BandC doesn't answer some questions... Basic SD-8 with the PMR1C-14... Just two wires coming of the SD-8 - connect to the two blue wires on the PMR1C-14. Black wire on the PMR1C-14 to engine case ground? Red wire via the Aux Alt switch (Carling 2GG51-73 15 Amp switch) to the fat wire tie point with a fusible link at the fat wire tie point? Any need for crowbar / overvoltage protection with the SD-8 against a PC680 battery when used for emergency use only? Do you consider having the battery and both alternators per the Z101B configuration sufficient redundancy for a dual electronic ignition aircraft? (ignition optionally fed from either side of the master.) I am considering running the SD-8 output also to one of my ignitions (third switch position on the ignition - EMER) such that if there's a hard short and I lose the entire electrical system, the SD-8 can feed one ignition. Dark and stormy night - electrical system goes dark along with the engine - flip Ign2 to EMER.
