Fifty (50) pin wire harness connectors attach to the controllers
connection terminal functions for the controllers and the wire harness connector
pins are identified in Figure
Because of the solid state circuitry built into the TEC, there is no method to test
the controller directly. A controller may be damaged if an attempt is made to test
it with an electrical test device (e.g. digital multimeter or test light).
Note: The Toro Electronic Controllers used on the Groundsmaster 5900/5910
are programed for correct machine operation. If either TEC is replaced for any
reason, system software needs to be reprogrammed (contact your Authorized
Toro Distributor).
