Hello, I was giving an 92 E-Z go Marathon. It had been used on a ranch in NM and the owner was moving and just giving it away. ( I think he found just was looking for someone to haul it away for him) Anyway After scraping and washing about 100 pounds of sand and dirt away. I have a OLD cart that I know nothing about so I will need a lot of help. 3 of the 6 batterys were dry. I filled them up and charged. for about 12 hours and all are holding 6+ volts for over the past 2 days. Took for the first drive today and it is so slow I could almost walk faster then it would run. Is there an adjustment for the motor or should I look samewere else? This will be just the first of many questions that I will have. I can do most anything with a car but this is all new to me so be kind if I ask some real dumm questions. Thanks
