[ARC5] Cleaning connector pins

[Paul Bernhardt]

Dean,

Often, the dynamotor, front and back pins/sockets for the receivers are 
filled with solder by the previous owner.  A hot soldering iron and a can 
of compress air does a good job of removing the solder.  Heat the pin until 
the solder melts.  Remove the soldering iron and simultaneously give the 
pin or socket a blast of compressed air.  A wire brush can be used to 
loosen the solder that was sprayed around during this process.  The heating 
and air blasting needs to be repeated a few times.  Each connector pin can 
be tested using metal sleeve that fits over the pin.  A drill bit that 
barely fits in a clean socket hole can be used to test the other socket 
hole on the input power side of the receivers.  Wear glasses when using the 
compressed air.
