Jim,

You know, even a broken watch will indicate the correct time twice a day.
If you only drive in circles, the compass will be correct once every
revolution. I know this doesn't solve your problem entirely, but at least
its a start.
Good luck!

I just got a little cheapie compass/clock/thermometer unit for inside
my M35A2 (don't worry...I plan to paint the little unit 383 camo
soon). I got this unit just so I can tell what time it is, but I
figured that having the direction and temp would be nice too. So I
thought.

No matter where I place the unit, the fluid-suspended ball compass
indicates North facing towards the dashboard. If I hold it out the
window or back toward the back of the front seat, it indicates in the
real North direction...it works fine.

Even if I place it up by the top of the windshield frame, it behaves
the same way...it indicates North to the front of the deuce regardless
of which direction the truck is pointing.

What is it under the hood or behind the dash of my deuce that is
acting as a big electromagnet?

I have not tried shutting off all power and checking the compass
because I just thought of doing that right now. Duh.

Any other ideas or experience with compass usage inside the cab of a
deuce? I'm just curious.
