FUEL SYSTEM-FUEL-INJECTED MODELS
NOTE
If it is necessary to charge the battery,
disconnect the ground cable from the
battery negative terminal before attach-
ing a battery charger. Failure to discon-
nect the battery can damage the ECU.
2. Before starting the engine, tum the key switch
ON and check the battery charge light. With the
key ON, the light should glow.
3. If the charge light does not glow, tum all of
the accessories ON and check the light again.
4. If the charge light still does not glow, the
problem must be isolated and corrected before
continuing.
a. Squeeze the throttle lever. If the charge light
now glows, the throttle monitor assembly is
faulty.
b. Check the fuse (Figure 3)-3 amp on early
models, 5 amp on later models. If the fuse
is blown, replace the fuse and check to be
sure the new fuse corrects the problem.

c. Check the condition of the charge light
bulb.
d. Check the DC voltage regulator assembly
and replace as necessary.
e. Check battery voltage with all the accesso-
ries switches ON. Voltage should remain
above 12 volts.
f. Some other possible causes are a faulty
ignition switch, emergency shut-off switch
or tether stop switch. Loose or corroded
connections to these switches could cause
the problem.
5. When the charge light is illuminated, check
the diagnostic monitor light (Figure 4, later
models similar) on the ECU, which should flash
one time. The single flash indicates current is
reaching the ECU and all the EFI components
are operating properly.
6. Start the engine. Once the engine starts, the
charge light should tum OFF. If the light contin-
ues to glow, the charging system is not operating
correctly.
