Multi Pro 5800Page 6 − 48Electrical System
IMPORTANT: When testing for wire harness con-
tinuity at the connector for the TEC, take care to not
damage the connector pin. If connector pins are
damaged during testing, connector repair will be
necessary for proper machine operation.
The machine electrical schematic and wire harness
drawings in Chapter 11 − Electrical Drawings can be
used to identify possible circuit problems between the
controller and the input/output devices (e.g. switches
and valves).
Because of the solid state circuitry built into the TEC,
there is no method to test the controller directly. The con-
troller 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 TEC and the InfoCenter used on the Multi
Pro 5800 are matched for correct machine operation. If
either of these components are replaced for any reason,
system software needs to be reprogrammed by your
Toro Distributor.
IMPORTANT: Before performing welding on the
machine, disconnect both positive and negative
battery cables from the battery, disconnect the wire
harness connector from the TEC, the wire harness
connecter from the ASC−10 on machines with
GeoLink spray systems and disconnect the
terminal connector from the engine alternator.
These steps will prevent damage to the machine
electrical system when welding.
