13-3
Problem 8
Battery will not charge and/or battery goes dead.
Probable cause
1. Alternator fuse blown.
2. Alternator diode bad.
3. Alternator resistor behind fuse panel bad.
4. Poor wire connections at battery, alternator, diode,
or fuse.
5. Excessive draw in off position.
a) Fuel gauge and hour meter should draw only
0.01 amps in off position.
6. Bad battery.
7. Bad alternator.
Problem 9
Loader control will not lock in float position.
Probable cause
1. Float magnet fuse blown.
2. Poor wire connections at fuse, float detent magnet,
or pin connector P18.
3. Faulty float detent magnet.
Problem 10
Loader will not float; labors engine and has down pressure
when detented into float.
Probable cause
1. Engine RPM too low.
2. Low charge pressure.
3. Pilot control malfunction.
4. Loader valve malfunction.
Problem 11
Hot oil light illuminates; hydraulic system operating hot.
Probable cause
1. Auxiliary hydraulic switch activated sending oil over
relief.
2. Low oil level.
3. Debris plugging oil cooler, limiting airflow.
4. Debris plugging A/C condenser, limiting air flow.
5. Broken fan blades.
6. Loose fan belt.
7. Improper attachment.
a) Attachment must be rated machines flow capa-
bilities.
b) Attachment hose size must be a minimum of 1/2
inch for low flow and 3/4 inch for high flow.
c) Low flow attachment hooked to high flow circuit.
d) Faulty hot oil sending unit.
e) Hot oil light should illuminate at 225°F.
8. Faulty quick coupler.
9. Cooler bypass relief.
a) Cooler bypass relief should open at 80 PSI.
Problem 12
Hot coolant light illuminates; engine operating hot.
Probable cause
1. Low coolant level.
2. Debris plugging radiator, limiting airflow.
3. Debris plugging A/C condenser, limiting air flow
4. Broken fan blades.
5. Loose fan belt.
10. Faulty hot engine coolant sending unit.
