Mooney M20E Power Boost wiring diagram

[Carl Everitt]

Could somebody please email the wiring diagram for a Mooney M20E power boost system

Thanks,

Carl

Pull the cable, the door opens.  This is the little door approximately 2” x4” above the air filter.  Most people will get about 1” rise in manifold pressure bypassing the air filter.

There is also the warning light that comes on if power boost is open and gear is down.

Somebody posted that schematic the other day in the J bar gear warning thread.

Where’s the switch located?

[N201MKTurbo]

The switch is on the power boost cable.

It’s gotta be on the instrument panel side.  The end of tgat cable is in a terrible spot just below #2 cylinder and on the other side of the oil cooler.  Mine came loose there once after the lower cowl was off and my mechanic was inventing some curse words.  I’ve never had to mess with the switch though.

I need the wiring diagram for the BOOST light circuit.

Thanks

@Ross,

Thanks for the diagram, it was a great help for GFC 500 install/avionic/panel upgrade

If you remove the oil cooler, which is only 4 easy bolts, you have easy access to the arm and cable.

It's been a while since I worked on one of those, but I think it is just like the switch on the throttle cable.

@Carl Everitt It's the same diagram. The horn, indicators, throttle switch, boost switch and boost light are tied to the gear warning switch.
