I have a 1994 EZGO Marathon, bought this cart 16 years ago and it has been good to me. I added a 4" lift Kit and 22" tires when I bought it. The only thing this cart ever needed was a set of battery's about every 4 years. Last week I put 6 new batteries in it and it ran fine for a couple of days. Now some times when you push on the peddle to go it won,t go. If you keep pushing on and off the peddle it will catch and go until you stop. Then it may or may not go when you tramp on the peddle.  

Any body know what is going on?
