With the ON Switch activated
5VDC should be present at the
Input Relay Coil. Terminal A1
(Red Lead) to Terminal A2
(Black Lead). See the wiring
diagram. If the green indicator
light is on the 5VDC should be
present at the relay coil.
Check for loose or faulty
connections between the Input
Relay, the Upper Terminal
Block and the ON Switch.
Check leads 101A and 103A.
See the wiring diagram.
If the 5VDC is being applied to
the Input Relay Coil and the
above mentioned connections
and leads are OK the Input
Relay Coil may be faulty.
Replace.
If the 5VDC is not present at
