Schematic.)
Starting Problems
Condition
________________________________________________________________________________________________________________________________________________________
Engine fails to crank, regardless
of traction bail position.
Hydroject 3010
Study the operating characteristics preceding the elec
trical failure to help identify the area of difficulty. Try to
isolate the failure to a specific functional system; then
check that area, repairing one component at a time.
Attempting to repair more than one system at one time
will lead to confusion.
Possible Causes and Corrections in the troubleshooting
charts should be checked in the order in which they are
listed.
If the machine being repaired has any interlock switches
by-passed, they must be reconnected for proper trou
bleshooting and safety.
Possible Cause
Loose or corroded battery connec-
tions.
Low battery charge.
Circuit breaker open.
Ignition key switch faulty.
Traction switch 1 faulty.
Start relay faulty.
Starter solenoid faulty.
Starter is faulty.
Engine is seized.
Loose or damaged wiring.
