TICO Manufacturing
ELECTRICAL SYSTEM PRO-SPOTTER
INTRODUCTION
The purpose of the ELECTRICAL SYSTEM section is to
provide service and maintenance personnel with
guidance on the proper procedures for servicing
electrical equipment on TICO Pro-Spotter terminal
trucks. The electrical system is made up of a 12-volt
negative ground system, power distribution center (PDC),
160-amp Delco™ alternator, and a Delco™ starter. It
also consists of switches, wiring, instruments, etc., which
are required for the electrical system to perform its
functions.
The TICO Pro-Spotter terminal trucks have been
engineered for quick and efficient servicing while
minimizing downtime.
For additional information, please contact TICO factory
support. (See “CONTACT TICO SUPPORT” on
page 0-15.)
ALTERNATOR
The TICO Pro-Spotter terminal tractor is equipped with a
160-amp Delco™ alternator. The alternator is located on
the right front side of the Cummins™ engine. When
servicing the alternator, follow these guidelines:
• Always disconnect the negative (-) battery cable
when the engine is stopped and the alternator is not
in use before servicing the part.
• Never disconnect or connect alternator wires while
the batteries are connected or the alternator is in
operation.
• Do not attempt to polarize the alternator or regulator.
• Never ground to any of the alternator terminals.
• Do not operate the alternator on an open circuit.
For additional information, reference the Cummins™
Operation and Maintenance Manual provided with your
TICO tractor.
