T7 Identifying Source Of Current Draw - Test
1. Make sure that every electrical component is turned OFF. Make sure that the key switch is turned OFF. Make sure that the dome lights are OFF. 2. Clamp a 9U-5795 Current Probe or 8T-0900 Ammeter around the main ground cable. Clamp the tool with the positive side away from the battery. Reset the probe (zero) before clamping the probe around the wire. Use the current probe if the draw is above approximately 2 amperes. Use the Ammeter if the draw is below approximately 2 amperes. 3. Monitor the current and remove fuses and breakers one at a time. Check the current after each fuse or breaker is removed. After removing a fuse or breaker and observing the current, reinstall the fuse or breaker. Start with the main fuses or main circuit breakers first, and proceed to smaller circuits. 4. If a removal of a fuse causes the current to drop, then the problem is in that circuit. a. Check if any components on the circuit are ON. b. If everything is OFF, disconnect electrical components on that circuit one at a time and monitor current. c. After all of the components in that circuit have been disconnected, check the current. If the problem still exists then check the wiring for corrosion or shorts to ground. The standard acceptable current draw is 50 milliamperes. A current draw above 50 milliamperes usually indicates a problem. However, some large machines with multiple electronic control modules have a higher acceptable limit. Contact a Caterpillar dealer for more information. T8a- Alternator Overcharging - Test
This test is for alternators with an "IG", "S", or other sense terminal.
1. Clean the connection and tighten the connection to the wiring terminal on the alternator. 2. Verify that the alternator B+ terminal nut is tight and verify that the wire has a good connection to the B+ terminal. 3. Many Caterpillar machines are equipped with a connector for the 6V-2150 Starting/Charging Analyzer. Use of this analyzer replaces the testing below through Step 8. Therefore, if the testing is good, go directly to Step 9. If the analyzer finds a problem, correct the problem and retest the system. Go to "Initial Troubleshooting Procedure". 4. Start the engine and set the throttle to at least 75 percent. Turn ON all electrical accessories for all test steps below. Allow the engine to run for at least 3 minutes before continuing to Step 5. The following table will assist in making calculations during this test. 5. Measure the voltage between the alternator B+ terminal and the alternator case ground. 6. Measure the voltage across the battery. Put the red lead on the positive battery terminal, and put the black lead on the negative battery terminal. Step 6 must be performed as quickly as possible after Step 5. Expected Result: On 12 volt
