Note

Sometimes incorrect wiring only causes marginal failures 
that standard troubleshooting cannot pin point. Always re-
check the connections into the unit and any other equipment 
associated with the circuit. Also, check the actual pin outs 
against the wiring diagrams.

The following cable illustration may be helpful in troubleshooting 
problems.
