two generator lights and a bus tie light, the

also illuminate. The diode is needed to keep
the other gen light off unless the computer
output activates the other gen light. </span></div>

Here goes but I dont have all the info, so this is
what you need to do: This assumes (oh no) that the
computer signals are positive on. the other end goes
to ground. If the other way around flip the diodes.<br>
almost any signal diode will work (a 1N4001 has a DC
Blocking Voltage or Vr of 50vdc, if you want more a
1N4002's Vr = 100vdc)<br>
I have inclosed a small diagram, and the 1N4001
datasheet.<br>

I did some more thinking (evil) bout your problem... <br>
a more realistic way would be the following:<br>
<br>
Right Gen/Field On/OFF (input to computer)<br>
Left " "<br>
tie switch On/OFF "<br>
2 Contactors to route power from generator to bus.<br>
1 Contactor to make tie bus.<br>
2 green lights for generator power ok <br>
2 red lights for generator Fail<br>
1 green light for tie bus<br>
1 red light for generator Fail<br>
most likely a meter to with a switch to switch between all your
buss.<br>
ALL led should be cpu driven<br>
that why you can turn off tie bus. or make it fail<br>
also you need a battery Contactor and switch, if you have a ground
power outlet you need a contactor for that also. and you gen
switches should be 2 pos with center off. UP = Ground Power (you
need both on (up) to have ground power on. Down = Generator ON.<br>
So if you want to charge your battery from your ground cart. here
what you need:<br>
1. Ground Cart plugged into the aircraft. <br>
2. " " ON (this completes the ground circuit)<br>
3. both Gen Switches in the UP or Ground Power (this with #2 pulls
in the ground power contactor)<br>
4. battery switch set to on.<br>
<br>
how this clears up the FOD.<br>
enjoy<br>
