Mvp 50s going in
 

My electric international mvp 50s are here and the panel is cut. Going to tilt it about a inch to inch and a quarter towards pilot side for easy Visibility.

I am also having MVP50s placed in my Skymaster (337A). They are currently in configuration and I'm having trouble finding a answer to a question they are asking. I've been looking through my manuals.

Maybe one of you has the answer to this question. On the suction gauge, there are two little red suction cups. When the suction drop below a level, the suction cups pop out indicating there is a vacuum failure. Does anyone know what that level is? I saw a post in the forum that at 1200 rpm, it should be 3.5 or above. My service manual talks about adjusting the relief valve and it should be 4.8 at 1900 rpm.

Anyone have a more definitive answer?

Nevermind, my A&P found it. I asked him what is was and I'll post here when he gets back to me. Just so its recorded if someone else asks.

Has anyone who installed MVP50P on their Skymaster added the individual gear up/down package? We are looking for the voltage that indicates an individual gear is up or down. I.E. it 0V for up and 28V for down.

There is an UNSAFE light, would that be the same voltages?

See the paperwork attachment and the circled areas. My aircraft is a Cessna 337A.

Thanks for any help,

Karl

I went on the Cessna Pilot Association looking for this answer. Someone was asking about this for a C182 and I believe the system is similar. They have 0V for Gear Up and 24V for Gear Down. I saw the wiring diagram after my last post. I can see the 24V along the Gear and Stall warnings. If anyone one else know the answer for sure, please post it.

Thanks,

Karl
