TESTING & TROUBLESHOOTING
Test Points
To aid in the troubleshooting of the control system there will be test points available for all relay board circuits . Used in
conjunction with step by step instructions in the service manual, a technician will be able to quickly and easily trace a circuit
to find a failure . Each circuit on the relay board will provide a solder filled plated through hole accessible to a DVOM probe tip .
This will allow the technician to probe a circuit without disassembly .
