was designed to
operate, indicating
an open circuit.
Additional
Notes
1. Test the output circuit for a short.
2. Test for proper resistance in the component
connected to the auxiliary TEC (P75, pin
42).
3. Swap the T2: Auxiliary controller with a
known-good unit (contact an Authorized
Toro Distributor for assistance).
