Figure A
Cut a 1" wire and strip 1/8" of
insulation off of both ends.
Resistance Testing #1 (If you do not have a meter, continue to page 11)
You will test the solder connections by measuring the resistance from the following points. If your readings are
different, double check your soldering connections.
