Little help with my 2000 club car golf cart

[Dan_k]

Scottyb it's really only had 1 speed fast I hit the pedal and it took right off there was no "crep" mode even if I tried to slowly do it it would just take off and if I put it in reverse it would hop and hop and then go into reverse like the motor was bucking I guess

Bump anyone have any ideas

Hooked up meter to pins 2 and 3 on controller with pedal up my meter reads 5.54 as pedal goes down meter goes down all the way to 0.9 so pedal is working right

I just noticed when I first turn cart on sit on seat and put it foward the Orange battery light comes on for a second and goes right off is that normal? If not how can that be the batteries are new just out them in i even tested each battery all around 8.4 and so on

Test your motor. You can use jumpers off two of the batteries for 16 volts. If the motor is bad, none of the other stuff matters.

I also tried to bypass everything and went right from the battery + side to the Orange wire on the motor and the cart runs great drives all over but the wires heat up and I stop right away I have done this 2 times with really the same result drives but wires heat up so I know the motor is good the pedal is good the fwd/rev switch is good

Any idea guys?

This is the confusing part, if the cart is wired correctly, when in forward, the orange wire is directly connected to M-.

If You put pack positive there, it would have fried the controller Mosfet as soon as it tried to turn on as it would be a direct path to pack negative.

The way You describe how the cart worked, is more in line with you putting pack negative on the Orange wire.

Please verify the wires go to the same places as shown in the wire diagram for your cart.

The throttle resistance test only proves the throttle is ok, not that the controller has the signal it needs.

The controller works on voltage, not resistance.

You need +48v on controller pin #1 when the solenoid engages.

You need to see the voltage go from 0v to 5v at the controller pin #3 as You go from pedal up to pedal down..

If the above is present, the controller is bad.

Thanks Sergio here's what I got

At red wire pin 1 I have 48volts when pedal is pressed in

At pin 3 yellow wire pedal in up position reads 0volts fully pressed in reads very low 0.152

As for the Orange wire situation here's what I did to make the cart run my last battery in the setup the battery that has the negative go to the controller on that battery if I take a jumper from the battery positive side and go to the Orange wire on the motor it will run like crazy just seems to have the wires heat up

I hope this helps you figure out my mess
