Brian,

Unless this was added by someone, it is not on the lift. Suspect your battery may be getting weak. Verify battery fluid level is good. Each cell should be filled to the top of the inner cell. Do not fill to the top of the fill hole. This will cause fluid to come out when charging. If the battery is 24 volt, it should read 26.5 to 27.5 when fully charged. Only charge a battery when it is discharged 80 percent. Charging sooner and more often will cause the battery to short charge and last for a short time. Newer batteries and chargers are different. Good Luck
