Question on 172 M electrics... (1974 Skyhawk II)

Hi All!

We do not have a wiring diagram (yet) for our plane.

The Cigar Lighter socket is dead, and we need to fix it to
power our new portable GPS. (or have a poower cable installed....)

Which 12V point (bus) should it be wired to? (dont want to
unwrap the harness to check out the wiring. )

Inline fuse or one of the panel breakers?

Would it have been disconnected for some reason?

(I have heard there was an AD on some aircraft to disco it)

TY!

Yep. As you've heard, there was an AD (at least in the U.S.) to either put it on its
own circuit breaker or fuse or to disconnect it. Most owners opted to disconnect it.

I don't know Canadian practice, but in the States there would be an AD log in the
back of the airframe logbook. Check the text of all those shown as complied with
until you find that one. I've been told that you can reactivate the outlet by adding
a breaker, but you'd need to check the AD text to be sure.

This marriage is off to a shaky start. The groom just asked the band to
play "Your cheatin' heart", and the bride just requested "Don't come home
a'drinkin' with lovin' on your mind".

Found it! discoed in 1983...

Looks like it can be reconnected if we install a fuse or
breaker in line...

Can anybody confirm this?

Sure. Just install a fuse or breaker. The fuse is probably easier.

You must have a mechanic perform the work in accordance with the AD
and sign off the compliance.

Anybody can do the work, the mechanic must sign it off.

Yes, correct to the extent that you describe, but not only must the
mechanic sign it off, but he must personally observe the work being
done before it is signed off. After the fact maintenence sign-offs,
though common, are illegal. Guess you want the reference? FAR 43.3
(d)

I should have used the word "inspect" instead of perform. Sorry.
