I just purchased a 2000 E-Z-GO TXT with Lift Kit and 22 inch tires. The batteries were all replaced in 2010. I test drove it in a parking lot and felt that the speed was running at 10 mph. When I got home I took it into the woods and attempted to go up a 25 degree hill that was only 10 feet or so long. I got stuck towards the top and had to roll back down. It is a 36 volt system. So, what should I be looking at here to troubleshoot this? The seller said this evening that the was correct since it was a TXT and not a PDS. I will do a 48 volt conversion next year but need to fix this now before deer season in a week. Thoughts?
