Multi Pro 5800Page 10 − 24Ultra Sonic Boom Kit (Optional)
IMPORTANT: Before performing welding on the ma-
chine, disconnect both cables from the battery and
disconnect wire harness connector from the TEC.
These steps will prevent damage to the machine
electrical system.

NOTE TAB POSITION
WIRE HARNESS CONNECTOR FOR TEC
CAN−bus Termination Resistors
IMPORTANT:The Ultra Sonic Boom Leveling Kit is
not designed to communicate with the machine In-
foCenter. Even though the communication network
is not being used, the termination resistors are re-
quired for proper electrical system operation.
The Toro Electronic Controller (TEC) used for the ultra
sonic boom kit has the ability to communicate with diag-
nostic/reprogramming tools via a CAN−bus communi-
cation system (contact an Authorized Toro Distributor).
Two (2) specially designed, twisted cables form the bus
for the communication network. At the ends of the
twisted pair of bus cables are two (2) 120 ohm termina-
tion resistors.
IMPORTANT: The termination resistor at the end of
the bus wires is required for proper electrical sys-
tem operation.
The CAN−bus termination resistors plug into the ultra
sonic boom kit wire harness. The termination resistors
are located below the ultra sonic boom TEC behind the
operator’s control console. The wire harness connect-
ors have a blue insert to identify the proper location for
the termination resistors.
NOTE: Refer to the Ultra Sonic Boom Kit electrical
schematic and wire harness drawings in Appendix A −
Foldout Drawings for additional information on termina-
tion resistor location and wire connections.

Termination Resistor Test
The termination resistors (Fig. 22) can be tested using
a digital multimeter (ohms setting). There should be 120
ohms resistance between terminals A and B of the ter-
mination resistors. Terminal C is not used on Multi Pro
1750 machines. Replace resistor if testing determines
that it is faulty.
If the resistor tests correctly and a circuit problem still ex-
ists, check wire harness (see Electrical Schematic and
Wire Harness Drawings in Appendix A − Foldout Draw-
ings in this manual).
