looking for a legible copy of ovation electrical schematic, cabin lights not working

[glenn reynolds]

my cabin lights are not working.  There is no power at the pilots armrest master switch.  non of the circuit breakers are labeled for lights etc.  the schematic in my service manual pdf is illegible (pdf).  the serial number is 29-0037 which the service manual references to an electrical drawing 800304 R2 W.  alternatively does anybody know which breaker the cabin lights come off of?

Thank You!  It would seem it was one of the three in line fuses in the battery area in the avionics bay in the tail.  I found two blown fuses, both now repaired.  As soon as I put the front panel and side panels back together, reinstall the seats, then I can fly it and confirm all works.  quite a goose chase.

Then the question is why did the fuses both get knocked out? Are they in series? And both blew simultaneously?

The fuses are not in series and not labeled so I don’t yet know which one is which. But I will know as I flew the plane yesterday and the fuse for the cabin light blew again so there must be a short. Darn front jack bolt broke so now I’ve got to have the engine mount repairsed so cabin lights are a low priority.

Oh no. Mechanical issue aside, searching for a shorted wire is so damned hit and miss. Good luck.

Yikes!

I threaded a bolt into the front engine mount and jacked up the front tire. The bolt broke so the jack slide forward and dented the tubing of the engine mount.

Bummer…

Jack points were rumored to come with the Ovations…

When ownership was transferred… I got everything but the Jack points…. 
 

I can only imagine what correcting a dent in an engine mount requires…
 

Best regards,

I’m learning that it requires time and money. How MUCH of those two resources I still don’t know.
