ELECTRICAL PANEL 5.7 The loader is equipped with a 12 volt, negative ground electrical system. The circuit breaker, fuses and relays are in a panel located in the engine compartment, just under- neath of the engine cover. (fig. C2485) To access the electrical panel: 1 Open the rear door and raise the engine cover. 2 Remove the bolt holding the electrical panel cover closed. (fig. C2485) 3 Open the cover and the circuit breaker, fuses and relays will be exposed. (fig. C2484) Visually check the fuses for burnt contacts. 1 Disconnect the battery grounds before testing or replacing the circuit breaker. 2 Remove the 2 nuts retaining the wires to the circuit breaker.
Be sure to note the location of the wires and the terminals they are connected to. There is a battery side and an accessories side to the circuit breaker. 3 Using an ohmmeter, connect a lead to each of the stud terminals and take a reading. Low resistance is normal. High resistance means the circuit breaker is defective and must be replaced. Cooling fan relays Fuse panel access C2485 The relays are identical and may be checked by swapping one for the other to trace a malfunction. If changing the relays around does not repair the problem, the problem is either in the wiring, or in the actual electrical component.
The ground bolt should be checked occasionally for cor- rosion and cleaned if necessary. Use a dielectric grease to protect the ground point from the elements. 5 Electrical Panel 2 3 7 13 1 4 5 6 8 10 12 9 11 C2484 ELECTRICAL PANEL LEGEND.(fig.
