Off/battery/alternator S700-2-10 switch
Can someone show me how this switch is to be wired? I've searched the net/VAF/Aero Electric...I have come up with many schematics, but I don't get the drawing of that switch.
What I need, is someone to lead my by the hand (with a picture of the back of the switch) to show me what wires go where.
Anybody have a pic of this? Single battery, single alternator...positions will be: off/battery on/battery and alternator on.
How???

Chad,
I would also be interested in hearing replies on this wiring as I am working on wiring in my plane as well.
I also have a question concerning the split alt/bat switch. However, I do not want to hijack this thread so I will post the question in its own thread here. |

Chad, look at the drawing in Bobs book. The switch contacts are numbered, and the schematic refers to these.
Z11, is the setup for what you want.

I don't have time to draw it, but use the EX11 AeroElectric article as a start:
http://www.bandc.biz/switches.pdf
On page 3, it shows the switch types -- 2-10 (on-on-on) is the switch you want. The top portion is the Master contactor control, the lower half is for the alternator. Here is the wiring layout:
#2 goes to ground
#1 goes to the master contactor. This way the master contactor is grounded when the switch is in the middle and upper position.
#3 is unused
#5 goes to the alternator breaker/fuse (5A typically)
#4 goes to the alternator. This is so the alternator is only energized when the switch is in the top position.
#6 is unused. |

Actually, to the regulator, be it internal, or external.
If you have an external regulator, make sure this wire goes to it, and not the alternator.

Sorry....I should preface the way I described was for the Plane Power alternator, which Chad is using. |

K...so #5 goes to an inline fuse off the main terminal on the Z-11 drawing...are people doing this, or can this be done with a standard 5A fuse in the main bus block?
Also, does the ANL current limiter come in to play with this switch, or is that just on the firewall side?
Man, I was feeling so good about wiring...then I hit a wall...

My comments were more for anybody who was following this thread, and might be confused by it.

Either way works.....I chose a circuit breaker off the main bus so I could reset it in flight.

The ANL is strictly firewall forward. |

Yeah, I don't want to get in to circuit breakers...my fuse panel will be accessible in flight thru a flip down panel. Can I wire this to the main bus with a 5A fuse, rather than off the main terminal?

That's what I thought...just wanted to be sure...
