4. If the battery is found to be good, or if the electrical problem continues after the battery has been replaced
with a good one, test the electrical circuits.
TEST PROCEDURE 2 – FUSE
See General Warning on page 1-1.
The fuse (red 10-amp) is located in the electrical component box.
1. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning on page 1-2.
2. Remove the cover from the electrical component box.
3. Ensure that wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
4. Remove fuse to be tested from the fuse block.
See Fuse Removal on page 14-14.
The red 10-amp fuse
protects the solenoid for the starter (cranking) circuit. The 20-amp fuse at the yellow wire connection pro-
tects the headlights and brake lights (if equipped). The fuse at the red/white wire connection protects the
horn.
5. Connect the probes of a multimeter, set to 200 ohms, to the fuse terminals. The reading should be con-
tinuity. If there is no continuity, determine and repair the cause of the fuse failure. Replace the fuse with
a properly rated new one.
TEST PROCEDURE 3 – GROUND CABLES
See General Warning on page 1-1.
1. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning on page 1-2.
2. Check the starter/generator ground cable.
2.1. Set the multimeter to 200 ohms. Place the red (+) probe on the (A2) terminal of the starter/generator
and place the black (–) probe on the vehicle frame
(Figure 12-5, Page 12-12)
. The reading should
be continuity. If the reading is incorrect, clean and tighten cable connections. If the connections are
good and the reading is incorrect, repair or replace the cable.
3. Check the engine ground cable.
3.1. Place the red (+) probe of the multimeter on the ground cable terminal end located on the oil filler
bracket on the engine
(Figure 12-6, Page 12-12)
. Place the black (–) probe on the vehicle frame.
The reading should be continuity. If the reading is incorrect, clean and tighten cable connections.
If the connections are good and the reading is incorrect, repair or replace the cable.
