Replace Batteries
IMPORTANT: Before adjusting the electrical system or
welding on the machine, disconnect the negative (-)
wiring from the battery. If the machine is equipped
with the battery disconnect switch, turn the disconnect
switch OFF.
Your machine has two 12-volt batteries with negative (-)
ground.
If one battery in a 24-volt system has failed but the other is
still good, replace the failed battery with one of the same
type. For example, replace a failed maintenance-free battery
with a new maintenance-free battery. Different types of
batteries may have different rates of charge. This difference
could overload one of the batteries and cause it to fail.
