Troubleshooting—Slow Cranking
If the starter cranks too slowly and the battery is charged and
in good condition, do a voltage-drop test to make sure the
starter connections are good.
When cranking, a voltage drop of more than 0.2 volts
between the starting motor cable and ground can cause hard
starting regardless of a battery’s condition. The voltage drop
can be caused by a poor contact between the cable terminal
and ground or between the clamp terminal and the battery
post. Poor start-switch contacts and frayed, broken, or
corroded cables can also be the cause.
Quarterly Battery Maintenance
• Thoroughly clean the batteries and the holder with a
baking soda/water solution.
• If provided, make sure the drain holes are open in the
holder. If water collects in the holder, drill drain holes.
• Clean the posts and terminals. Lightly coat the posts
with petroleum jelly to prevent corrosion.
• Replace frayed, broken, or corroded cables.
• Replace the batteries if their containers are cracked or
worn to the point they leak.
• Ensure a good tight contact between the clamp
terminals and battery posts.
• Make sure the hold-downs are tight enough to prevent
battery movement but not so tight to cause distortion.
BATTERY DISCONNECT SWITCH
The battery disconnect switch (Figure 7-3) is located on the
right side next to the engine controller box.
The switch disconnects the engine controller (Node 0) from
the positive side of the battery. Since the rest of the crane’s
control system is powered through Node 0, opening the
disconnect switch effectively removes power from the entire
control system.
To operate the battery disconnect switch:
• Turn handle COUNTERCLOCKWISE to DISCONNECT
the control system to the battery (handle horizontal/
removable).
• Turn handle CLOCKWISE to CONNECT the control
system from the battery (handle vertical).
The following are reasons for using the disconnect switch:
• When servicing crane’s electrical control system.
• To help prevent batteries from discharging when the
crane is stored for extended periods of time.
• To prevent crane from being started by unauthorized
personnel.
CAUTION
Engine Damage
To avoid possible engine fault codes and undesirable
operation, make sure engine ignition switch has been off
five minutes before disconnecting batteries.
Do not rely on this switch to protect crane’s electronic
systems when welding. Disconnect battery cables at
batteries before welding.
CAUTION
Potential Control System Damage
Before Welding:
• Disconnect battery cables at batteries.
• Disconnect the cabling from any control node
enclosures that are in the vicinity of the welding.
Do not rely on the disconnect switch to protect the crane’s
electronic systems when welding.
