I have a VOR/ILS indicator made by Mid Content Instruments (MD200-306) and I

am trying to figure out if it is lighted internally or if I need to supply

some sort of lighting.  The (Spartan) instruction manual shows lighting

connections but I'm not sure if they are for the annunciator lights or for

full facial lighting. Those who've used this instrument in your panels, do

you remember if it is internally lit or will I need to supply post lights or

something similar?  I emailed Mid Content Instruments several days ago about

this but apparently their entire technical support department is on an

extended vacation!  Thanks for all the help.

   I found a diagram calling out connections to the MD200-306 at

   Seems that 19, and 20 are 14 and 28v annunciator power.

   23 and 24 are 14 and 28v dimmer for illumination. These

   might be the same sources if you want the illumination and

   annunciation to track.

Dean,

Hooked mine up a few weeks ago.  The Annunciator lights are

the little words, like GPS, and NAV.  Yes, you need to

put in a dimmer circuit for the backlighting. No post lights

needed.  You give it the dimmer voltage at pin 23, and hook

pins 22 and 21 to ground.  You won't use pin 25.   You can

use all sorts of dimmers, but I used the $20 one from

Van's.  Simple and works fine for the job, and I dim 3

other items with it as they are all fairly low draw.

Dean -



We wired a lead from the dimmer buss to pin 23 of the MD200 (12 volt  

system). Works fine to dim the instrument.

Thanks for all the info on the MD200-306 VOR/ILS Indicator lighting. I got a

little confused looking at the pinouts on the connector and there wasn't any

elaboration about it in the rest of the manual. But I figured the answers

could be found on the list.  Where would I be without it!
