I have an expensive auto compass -- but I've lost the instructions --
with a wire in which both halves are black, but one side is marked
with grey or white rectangles. Which one is the ground?

Thanks

If emailing, please let me know whether
or not you are posting the same letter.
Change domain to erols.com, if necessary.

Try both. Low voltage DC, you wont damage anything. The one that makes
the compass point the right way I assume is the correct one. Also
consider that its for a light or something and it does not matter.


An electronic auto compass may NOT be protected against reverse polarity.
Try finding the manufacturer online and maybe they will have the
instructions online,or will send you a copy,or tell you in an email.

It would also help if you posted the *make and model info* and any numbers
on the case,maybe someone here has the same item,and can help.

Also try rec.autos.driving or other auto-related NGs.
