Ok after careful review the motor will fit as long as you have a 19 spline which the marathone did...geez lol

should the solenoid be 40 volts on 1 side and 35 on the other? with key off?

Ok i managed to drive sitting on the floor depressing the pedal and hit a hill i kep it wide open throttle which was a crawl at this time got over 38 volts everywhere while driving besides at the motor. 24 volts at the motor on S1 under wide open throttle. Does this say anything? Please

Ok mybadomen, I just physically got a g16 36v from my rental fleet and drove up a steep hill with throttle wide open...cart started spinning out and voltage at S1 was exactly 24volts...hope that helps any...I guess thats normal cause this is a perfect operating cart

I have a Fluke multimeter.

Why are you swapping batteries constantly?

What type charger do you have? How is acting? Amps, how long, voltage, etc? What is your pack voltage several hours after a charge?

From your description, it sounds like the since you fixed the brushes, the cart runs just fine, but has no range. Which to me says, "batteries".... I know you say they are new, so, is the charger charging them back up properly?

I am swapping batteries from my EZ-GO thats a 1986. the batteries are brand new i havent had them 1 month yet and the EZ-GO fly's with them. When charge is hooked to pack i get anywhere from 42 volts to 45 volts without the charge it is a little over 38 volts while testing for hours. I swap the batteries because i will only be using the Yamaha if i can ever get it fixed. but i still need to use the EZ-GO for work so each test i need to swap batteries. Lol many times a day for day 5 now today makes of non stop working on it. My back is totally shot.And still no idea whats wrong. and no the cart acts as it did the day i got it even after all the work .

Anyone know where you get Re-manufactured Controllers. The guy at the camp ground beginning of the summer paid $260. for a re Manufactured Yamaha Controller that is the same model as mine. He cant remember where though .He remembers its Florida Cost $260. as long as you have a core. $360 without a core.

Anyone know of one of these places ? Id rather spend $260 and find out its not the part that i need then 400 to 1000. Still have my doubts its the controller but going to replace that first .

Thanks Guys
