Pass The output circuit tested good. Go to Step 3.
Fail The output circuit did not test good. Replace
Step 3: Check that the output is not shorted.
The output current signal flows from the primary TEC to the 48V logic relay. Test the wiring at the relay to
ensure the voltage signal is reaching the relay. The 48V logic relay is located under the right side cover. It
is a 5-terminal relay with a 12-volt coil.
1. Remove the right side cover to access the enable relay wiring.
2. Disconnect the machine wire harness from the enable relay.
3. Turn the key switch to the R
