CAUSE REMEDY
Defective two block switch...................................................................Check for correct mechanical operation. If OK,
remove cover and wires from terminals #1 and #2.
With arm pulled down, there should be a closed cir-
cuit between them. With the arm up, the circuit
should be open. If all conditions are not met, replace
switch.
Defective relay in panel.........................................................................Check for 12 volts between relay pins #30 (hot) and
#86 (ground). If voltage is 0, check for voltage
between pin #87a and ground. If 12 volt, replace
relay (With no electrical power to the relay, pins #30
and #87a should show continuity. With 12 volts to
either #85 or #86 and the other grounded, there
should be continuity between pins #87 and #30.)
