B767 Electrics
 

Hi everyone!

For a project a friend of mine and me are working on, we need some information on the 767 electrical system.
More precisely:
What bus(ses) power(s) the indicator lights on the overhead?
Such as the Qty light for the hydraulics, or the ISLN light in the Bus Tie Breaker...
I figure most, if not all, lights will be powered by the Stby DC Bus.
Are there any other busses involved (Left DC bus...)
Thanks for any hints!

Kind regards,

Mark
