[simpits-tech] Tech Help Needed: Aircraft Power

[Jim Sturcbecher]

I would fully agree with Darren. You really need to know what belongs to
which circuit function, and VERY carefully check for problems where the
original wiring has been chopped. When you have sorted it all out and found
the wiring that you need to use, I would also highly recommend that you
re-introduce some safety circuits (fuses or breakers) into the new feed
wiring just in case anything got missed. Be ready for more work than you
first anticipated.

Good luck,

Jim.
