Help with Yamaha Golf Cart please.

Wouldn't hurt to take the f/r switch apart and clean it. Doesn't cost any $$$ either.

My problem was the motor. All the shuddering was the motor.

Wow now that sounds promising . so if my motor don't turn with 3 batteries its junk? If it does turn its the controller?

Even better news i may have found a controller for 100 bucks in my area if its any good.

Waiting to hear back from the guy to go take a look,Maby he has the Motor for 100 also :)

My motor turned with two batteries, three, and all six. What I was suggesting for you since your cart wants to run slow was, to get a nice open area where you could jump the whole pack across the motor and let it rip and see if it slows down like when you use the controller. Do not put the full pack on it with no load. Leave the motor in the cart and jack up the back or run down the road.

For $100, if it is good, might be a handy spare to have.

How do you like the Duracell batteries? I was looking to maybe get them.

well out another $360.00 on a Controller and doing the same thing. Now Broke 2 good controllers and a cart that barely moves. This is ridiculous really.So bummed because i could have bought a really nice cart the cash i have invested in a cart that still wont go.And the summer is almost over.Nor me or my kids got to enjoy it.

I will tell whats going on again to see if it helps and maby someone ran into this before. I bought the Yamaha Cart 1998 C16E 36 volt . The guys told me right away the batteries were junk but it went slow even before that happened. I bought all new batteries and cables for an old cart i had an EZ-GO 1985 Marathon resistor cart. The guys did say he replaces the thing in the pedal . the potentiometer but it didnt help. so that was brand new.I Put the perfect working batteries and the cables from the EZ-GO into the Yamaha and pulled out of the yard and was barely moving. came back talked to you guys cleaned every single connection on the cart including pulling the motor and checking the brushes. Still same thing.

Finally i took it for a ride with no seat on it and noticed with the pedal to the floor i got 38.5 volts everywhere besides one spot and thats coming out of the controller to the motor. I only got 24 volts there i had this gut feeling it wasn't a controller but i finally saved enough to buy one to only find out i was right. I just threw $350.00 out the window and now have 2 good controllers.

Please someone help me with this! It has mentally and financially killed my family and out summer as every dime we have has been put into getting this to go for months no and the same thing.

Thanks guys would be so in debt if someone could figure this out. My dad has the same cart with old batteries and they go very well.Which is the reason i bought it in the first place.

Take care and will keep checking back

Did you ever try taking the f/r switch out and cleaning everything like I did? I'm by no means an expert, but it fixed mine and wouldn't hurt to do it. Besides, it's free!

working on that right now as we speak the F/R switch but i had a question should the controller be getting extremely hot? Me and my wife took a little ride around the park hoping it would kick in and go but it wouldnt. but we went up a hill and almost didnt make it. so i lifted the hatch and felt the controller was very very hot and felt a tiny bit of heat from the f/r switch. but for the controller to be that hot its either got to be a normal thing or problem after the controller right? I am not sure i only know basic electronics so its more of a question.

racinjason89 did you mean clean the connections on the F/R or does it come apart. It looks like its a sealed unit to me but that's with it in the cart still
