Bob or any other electrical wizard...

  

 Used a S700-2-1 DPDT on-off-on switch to wire my  avionics master switch to include panel lights for 'main bus' and 'bat  bus'.

 wired it like this:

                            #3  bat bus & light  post           #4 light  post

                           

                            #2  avionics  bus                      #5  grnd

  

                            #1  main bus & light  post          #6 light  post

  

 When I toggle 'bat bus' instruments come on   -  no light

 When I toggle  'off'                                        -   everything off

 When I toggle 'main  bus'                               -  everything off

  

 When I turn master switch on(battery Cessna Split  Switch)

                         'bat bus' instruments come on  - no light

                        'off'                                          - everything off

                         'main bus' instruments on - no light

 What am I doing wrong to get no lights?   New switch from B&C. Lights from B&C 12V  - Lights work-checked  separately direct to battery.

 Thanks in advance.

   Mike, can you do a schematic of how your system is wired

   and post a scan to the List? I'm not sure my mental image

   based on your words is an accurate depiction of the electron

   map.

Bob,

I figured out what was wrong.  I didn't realize that the indicator lights 

were LEDS and must be wired differently from bulbs.  White dot on side of 

light housing apparently meant 12v source.  When I wired it that way(had it 

reversed) the lights came on.  HooRahh!.

Thanks for responding,  wiring is completed-at last.
