ADAPTER AS 1436890 - Caterpillar

off the fuel supply in order to prevent the engine from starting during this test.This test will activate all of the cranking circuits, so that the 6V-2150 Starting/Charging Analyzer can measure the voltage, in relation to the components on the following circuits. The analyzer performs the following checks:
The analyzer checks for an excessive voltage drop on the starter ground circuit.
The analyzer checks that the battery voltage is within the expected range for cranking.
The analyzer checks the alternator circuit breaker for an excessive voltage drop. The analyzer also checks if the breaker is activated.
The analyzer checks the key circuit breaker for an excessive voltage drop. The analyzer also checks if the breaker is activated.
A check for an excessive voltage drop is performed on the key start switch. The switch or the harness could be open.
If equipped, the main relay is checked for closed contacts. The breaker is checked for activation.
The analyzer checks if the coolant switch is CLOSED. Note: It is possible that the machine does NOT have components for starting aid. Also, the machine may have an automatic starting aid system.
The analyzer checks that the starting aid switch is open. Also, the starting aid solenoid should have a closed circuit.
The analyzer checks if the start relay is CLOSED. The analyzer also checks if there is an excessive voltage drop across the contacts.
The analyzer checks the power circuit of the starter solenoid. A check for an excessive voltage drop is performed.
The analyzer checks if the starter solenoid contacts are CLOSED. The analyzer also checks if there is an excessive voltage drop across the contacts.
