COMPONENT TESTING
Before testing any of the components, perform
the following checks:
The most common cause for control failure
is corrosion on connectors. Therefore, dis-
connecting and reconnecting wires will be
necessary throughout test procedures.
All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.
