Clock

[Tom Cummings]

I had a brand new Mid-Continent MD-90 clock installed in my Cessna 172. It
runs real slow and I would like to know is there a way to adjust the clock?
Thanks,
Tom

Sheesh, you would think that having the clock installed in the
airplane would make time fly!


.... oh, come on! Someone was going to do it - it was my turn ;-)

I would think a brand new clock would come with literature explaining it's
operation.

Unplug it ....wait for 12 hours, plug it back in?

Nope, no instructions or literature included-just a manufacturer's origin
document.

Thanks Monteblack,
I contacted Dallas Avionics from the website you gave me and they gave me a
tech number for a Mid Continent representative. (Mid Continent's website
doesn't provide a tel number).
The technician said there is no way to adjust the MD-90 clock and they will
send me a new one and I send the other back.

I'll see your pun and raise you a geeky 'nother:

"I would say that your 172 is *a lot* faster than most if your clock slows
down when you fly it" (think Einstein)

Yeah, but the pilot wouldn't notice it running slow.

I hear about pilots who can't keep up with their planes all the time.

(Well, in a 'hawk, it's more likely being unable to keep up
financially than speed-wise.)

Well, this was a cheap way to fly more nm per clock hour!

Actually his fuel consumption would increase over time, but he would fly
more miles per given hour...

I wrote last week about adjusting a Mid Continent clock that was running
slow. The factory said it could not be adjusted.
As it turned out, on my Cessna 172, it was not the clock at fault afterall,
but a corroded fuse holder mounted on the firewall in the engine
compartment. Only 2.5 volts were getting to the clock and the circuit had
6000 olms resistance showing on it. Other times, no voltage would get to the
clock and yet the fuse was not blown. After cleaning the fuse holder, 12.5
volts were detected in the circuit, and the clock runs perfectly now.

With so many of us using 30 year old wiring, it's a wonder there aren't
more problems like this.
