We have a 36 volt cushman cart that does not want to charge, we replaced the batteries all brand new from interstate, the charger does not kick on, we ordered a new charger and the new one was installed, the charger kicks on and turns off, what could be the issue since the charger does not want to stay on??

Hello! Welcome to fixaforklift.com

The main charging signal comes from the controller that is located underneath the board that covers the batteries, their is not really a way to simply test the controller but you can determine the symptoms of a failed controller, Their is a MAIN contactor that should be checked as well by placing the negative probe on the negative side of the main battery and probing both studs on the main contactor, they both should read battery voltage with key ON,

if voltage is at both studs follow the wire going to the controller that bolt at the wire should have power as well, if it does and truck does not move nor charge, controller is bad and needs to be replaced!

****UPDATE****

The cushman part number straight from the factory reads 602718 which is also the same as Lester 649157
The original part number from the cart's onboard charger is 602714 BUT this part number charger calls for send in and have it repaired only.

If you order a new one AKA Part number 602718 it is the same charger but it will not charge nor let the truck runs since its missing the kick down relay. The best way to repair the charger is to open it up and find what part needs replacing, if you did order a new one all parts are interchangeable. The Titan Burden Carrier Number Service Parts manual number is 605878
