737 Fire and Master Caution switch Booster PCB

February 08, 2016, 06:08:22 AM

Hi,
I have the Engravity / Cpflight MFB280 booster PCB's, one for each MC & F switch - total of 4.
It is designed to give a 12v boost to the lights in the units, as they are rather dim when powered from the CpFlight MIP737 board.
Does anyone have the wiring diagram, to say which wire from the screw terminals of the unit goes to where ?
Screw terminals are numbered 1-8.
I have attached a pic of the unit in question (I hope).
Many thanks.
Best regards,
JP
