Lol gotcha...I think I will start with the existing motor first and see how it does as you suggest.

Your stock motor will live just fine on 48v too. And 33% more speed & torque.

Re: Does anyone have a 1987 Yamaha G3-E Sun Classic Electric Service Manual?
So what would everyone recommend as far as the best controller and other parts needed to switch over to 48v? I'm in a hilly rv park so the more the merrier. Which controller 300, 400 or 500 would be best; and what other parts would I need to make this complete switchover while keeping the original motor? I would love to know the best route as well as most cost-effective if possible.
Thanks so much in advance for all of these great solutions :) |

A G3 is a somewhat heavy cart, so I wouldn't go with a controller smaller than 400a. I would suggest the Alltrax SR-48400, a PB-6 throttle, all new 4g cables. The current solenoids are heavy duty enough for a 400a controller, but they may be 30 years old.

Re: Does anyone have a 1987 Yamaha G3-E Sun Classic Electric Service Manual?
Another question... Would I be able to run 48v batteries through the existing original components without the new controller etc just for testing purposes? Anotherwords, can a stock G3 run 48v without making any other changes to the stock components?
I'm just curious since I have a mostly unmolested cart without any batteries; if starting with just new 48v system would word straight away? |
