TROUBLESHOOTING BATTERY CHARGER
Insufficient AC system, poor connections, bad batteries or low electrolyte in batteries may result in
poor charger performance. Refer to
Section 2: Electrical System for electrical requirements, and
charger and battery maintenance instructions.
Refer to the Operator’s Manual for detailed charging instructions.
To be able to use the trouble shooting guide safely and effectively, it is important to read through this
guide before beginning any tests.
Do not operate the charger if it is malfunctioning. Personal injury or property
damage may result.
Do not disassemble charger. Return to MEC when service or repair is required.
To reduce the risk of fire, only use AC circuits and extension cords in accordance
with all National and Local Electrical Codes for the location of use.
Only use MEC approved lead acid type flooded batteries. Use of GEL type
batteries may damage the charger and cause machine instability due to
decreased weight.
TO REDUCE THE RISK OF ELECTRIC SHOCK, ALWAYS DISCONNECT BOTH THE
POWER SUPPLY CORD AND THE OUTPUT WIRES BEFORE ATTEMPTING
MAINTENANCE.
THE CHARGER SURFACE CAN GET HOT WHILE OPERATING. CONTACT WITH THE
SKIN OR SURROUNDING MATERIALS SHOULD BE AVOIDED.
TO REDUCE THE RISK OF AN ELECTRIC SHOCK, CONNECT ONLY TO A PROPERLY
GROUNDED SINGLE-PHASE (3 WIRE) OUTLET.
Incorrect assembly may result in a risk of electric shock or fire. The following procedures are intended
only to determine if a malfunction may exist in the charger. Most returned chargers test good, it is very
important that this procedure is followed and that other problems are corrected before assuming the
charger has failed.
The MEC battery charger is a fully automatic type with a maintenance feature that will maintain
battery voltage indefinitely when connected to an AC power source. The battery charger should be
plugged into an unswitched AC power source if the machine is stored for long periods of time.
IMPORTANT: All MEC electric scissor lifts are equipped with lead acid type flooded
batteries. The yellow wire loop on the back of the charger must be
intact. If it is cut, broken or damaged the charger may go into GEL
charging mode, causing damage to the machine and/or batteries.
