Good morning/evening, I am new to this forum, new to Yaks and new to flying so please forgive my lack of forum manners.
I own a Yak18t, I have a million questions but the most pressing at this stage is the red illumination bulbs which fold down above instruments do not operate. On the switch panel on the right hand side is a instrument lighting switch and a variable Pot which I assume operate the lighting. My question; is there a common problem with the instrument lighting I should look at first before I go hunting around at all the other possibilities? Is there a fuse anywhere?
Also while doing the 100 Hr I discovered a very large electrical piece of equipment under the rear seats on the right hand side with plugs and switches on it, all appeared off, anyone know what this is?
Thank you all in advance
Andrew Park

The 18T has a very complex wiring system, and you really do need a wiring
diagram for any serious fault finding-But that would seem to be a circuit
breaker-on the 18T all the switches also act as breakers.
The box is the relay for all the equipment in the rear of the plane-like
most of the avionics which are behind the rear seat.
We rebuilt an 18T and saved 106 pounds on the electrical system alone!

No surprise at all. When I pulled the wiring from my CJ6A "Project" I put it all in a box and threw it on a scale -- 110lbs (50kg). I expected the replacement electrical system to come in under 10kg and probably closer to 5kg.
Most older electrical systems are unnecessarily massive and complex, with many things done by tradition rather than engineering.
