INTRODUCTION:

• This section describes the electrical system of the TR89 and TR99 combines. The electrical system has been broken down into sub systems and circuits according to functions performed or monitored. The Table of Contents lists the sub systems and circuits.
• Each sub system and circuit listed contains a description of the electrical circuit. a schematic of the circuit. and diagnostic test procedures based on the symptom(s) that a system may demonstrate. Read all the introductory information before starting any test procedure. Next, look through the test procedures and locate the correct symptom. Use that test procedure to locate and correct the problem.
• Follow the steps as instructed. Do not skip steps unless instructed to do so in the test procedures. Prepare the machine for the test by following the pretest instructions. Perform the test and observe the results. Perform the indicated corrective action. Continue through the test procedure until the problem is corrected. then return the system to an operational condition (replace shields. etc.).

DEFINITION OF TERMS :

• ALTERNATING CURRENT (A.C.) – A flow of electrons which reverses its direction of flow at regular Intervals in a conductor.
• AMMETER – Measures the flow of electrical current in amperes. Ammeters are connected in series with the circuit to be tested.
• AMPERE – A unIt of measure for the flow of current in a circuit. The ampere is used to measure electricity such as “gallons per minute“ is used to measure liquid flow.
• CIRCUIT – A continuous. unbroken path along a conductor through which electrical current can flow from a source. through various units. and back to the source.
• CIRCUIT BREAKER – A device to protect an electrical circuit from overloads.
