[TenTec] On cleaning connectors

[Bob McGraw K4TAX]

Seems that I keep preaching this topic over and over and over. I 
recently addressed this issue on a Scout and a Century 22.

Fact is, connectors oxidize.  It is the laws of chemistry and physics 
and has little to do with the conditions where the radio resided, past 
or present.  When connectors oxidize the electrical path is interrupted 
by the thin layer of oxidation.

The solution is simple.   CLEAN ALL OF THE CONNECTORS.  Thus removing 
the oxidation and the radio returns to normal operation.    Just be sure 
to exercise the male connector on the female connector a couple of times 
and then be sure the connector is correctly and fully seated before 
moving on to the next connector.

As to the cleaning process;  a Q-Tip with contact cleaner applied, {your 
choice of the magic chemistry} and then scrubbing the male pins is all 
that is necessary.    No hocus pocus, black magic, or voodoo act 
required.   And while you are in there.........DON'T screw with anything 
else.
