1990 EZ GO Marathon


New Member
My problem is the golf cart would only go about 3-5 MPH before I changed the batteries.I bought new batteries and its still going about 3-5 MPH with the new batteries installed.It can go up some hills(this is on my farm)Hills of Grass,Rock,Dirt,and road at about 2MPH.Also I can hear tiny clicking from the back of the cart when going forward.(that may be a clue I don't know) Ive been told to test the controller,Pot Box,and Motor.What do you think it is? What do you think I should test or do? Could I also have instructions on what you think I should do (How to do it)

My name is Matt

Thank You Very Much



Welcome to the forum...

Test the pot box and motor first. If the clicking you hear is coming from the motor it could be worn brushes or a bad armature.
