I'm not familiar with the LIV speed brakes. If
they're cable operated, where does the 14V come in ? If the 14V is just for the
indicator lights then no problem, replace the bulbs.
As for the 14V hydraulic pack and heated pitot,
those are two of the heaviest uses of electricity. Inverters or dropdown
regulators are not practical. Replace them with 28V units.
The question is what is less cost, replacing those
two units with 28V or replacing the dual alternators with 14V

Subject: LIV 28v to 14v
I have 14v (a) Precise Flight cable operated speed brakes;
(b) hydraulic pack; and (c) heated pitot tube all installed and working in my
LIV project. However I have acquired a TSIO 550B with a (dual
alternator) 28v system. I would like to go with the 28v system but I hate to
go backwards (not to mention the expense) to retrofit my 14v equipment.
I am wondering if it is possible/advisable to run a 28v system but
utilize my 14v equipment by installing individual transformers for some or all
of (a), (b) or (c) above? Thanks for any advice any of you may
have.
