I'm looking for the Bob K as drawn Z-14 dual power wires through firewall with crossfeed contactor on the firewall. I have seen many of the nice single power wire with the contactors in the back of the plane but will be using the crossfeed contactor on the FW and split busses. Just curious how others have decided to arrange the components up front in their installations for this. Thank you. ________________________________ Message 2 _____________________________________ Time: 09:15:15 AM PST US Subject: AeroElectric-List: Re: Non-aero app: 120/240 AC through 24vdc switch? From: "jonlaury" Bob, A thousand thanks! And I found your explorations and findings about the relay failures on rolll trim control boards fascinating, if for no other reason than the failure symptoms are almost identical to what I'm seeing with my product. My switch failures are beginning to occur after about 30-60 cycles. Thinking that the sticking was purely mechanical, and acknowledging the problem to users, I suggested unplugging the machine, squirting WD40 into the pushbutton recess and cycling the switch until they got a blister on their finger, to erode/smooth the imagined rough edges of the switch internals. It either worked or customers just didn't want to talk to a crazy person any more, because very few reported a continuing problem. I even rigged up a reciprocating saw with a 'boxing glove' to wear-in the switch, as a misguided, pre-conditioning preventative. Your analysis, with remedies, is a crescendo of angelic voices, coincident with brilliant, golden light, illuminating the path out of blasphemous tinkering to electronic righteousness. I feel cleansed. :D One more impertinent question: In the zero-crossing relay suggested, the load side spec is 250vac @ 2a. The steady-state ballast load is 800ma and the motor draws about 2a. Will the relay take it? or am I missing something here?

This way I only ran one 'fat' wire (2awg) up to the starter contactor and Bus 1. The other wire was an 8awg for bus 2. All the interconnections between the 3 contactors are 2awg but they are very short runs as you can see here . That seemed to me to be the most efficient wiring and placement scheme for the Z14 in a '10 but I'm sure there are other considerations. Please ignore if you've already considered this in favor of a firewall install.
