Jumper Pins 2-3 for No Battery Configuration.
P7, PlO & P13 are factory-adjusted. These circuits are not field adjustable.
P16
Jumper Pins l-2 to enable Earth Detect.
Jumper Pins 2-3 to disable Earth Detect.
Connectors
Refer to Field Wiring Diagrams 841-843 and 841-845 for harness interconnections. Refer to Publication FA4-21-234
for additional information.
