Master solenoid

Thanks Gary, that is a great demonstration of the reason to have diodes on our relays.

Got 'em on all three of my "master solenoids".

Three Wow I thought I was bragging when I say I have two, One for me and one for the little boy that lived in a shoe, E-I-E-I-O (like me he has a solenoid for his starter).

(I used master solenoids to also power up my dual landing and dual taxi lamps so I would not have to change the cockpit switch or placarding.)

Sorry George, I thought you were pulling on my oh so short chain----------------again!!!!!!

Hi All
Does anyone know where I may find the plastic cover to my solenoid/contactor mounted on the battery box? The plastic cover is junk but the solenoid works fine.

Dick, I'm afraid you are one of the few, like me, who is still running the original solenoid. Many don't know what the original looks like.

This particular example I bought at convention action for a few dollars. Our Parts and Maintenance coordinator came over to my table and asked what I intended to do with it. I said keep it for a spare. He looked at me and said that it was not the correct solenoid for our 170s. When I explained that indeed it was the original he paused and gave me a look, then retreated back to his table realizing he missed out on such a treasure.

Me too. It needed a minor repair last year, but the contacts were still in perfect condition. And I touched up a crack in the cover with JB Weld.

I don't recall saying it wasn't the "correct" solenoid. (I may have said it's not the current part no. perhaps?)

Wasn't there beer being served? Could explain a lot.

My version of the story is better.

George, will the ACS Starter Solenoid Diode Assembly (16050-2) that you previously mentioned from Spruce be sufficient for both the Master and starter solenoids? I have a key start. Thanks.

Joe

[GAHorn]

Yes it will. The diode actually protects the switch from damage (and in some circuits also prevents surges from hitting avionics.)

[Joe Moilanen]

Thanks George!
