Replaced transformer go cart only goes reverse witch wires would be crossed?

Looking down on the f/r switch , the bottom contact is A then moving clockwise you get B, C , and D.
So C (top) would connect to A2 of the motor and also to A2 of the controller if there is an A2, Some controllers do not have an A2.
B would go to S1(F1) of the motor.
A would connect to B+ of the controller.
D would connect to S2 (F2) of the motor.

check the wires from the accelerator pedal to the solenoid (fuse)
replace the solenoid

they should stack naturally, but crossing whould not hurt them,,inside radiator is just a cool tank

Here is standard wiring on a low voltage transformer:

"r" on transformer goes to "r" on thermostat (use red wire)
"w"on transformer goes to "w" on thermostat (use white wire) (this is heat)
"y" on transformer goes to "y" on thermostat (use yellow wire) (this is cooling)
"g" on transformer goes to "g" on thermostat (use green wire) (this is the fan)

"c" (if used) goes to "c" or thermostat
"o" (used only on a heat pump)(orange) (reversing valve)

note: on most thermostats if you have an rc and an rh, they both must be jumpered together and use them as "r" (red)

Either wire can go to either line as long as it is only one line lead to each post. Rotation is fixed and unlike a three-phase motor, reversing the two wires does NOT reverse the motor rotation.

Your batteries have died. The reason it will barely move in reverse is that current is being supplied to the motor is a direction that it spends very little time using. There is a slight change in the armature over time, and reverse tends to work better over time. Check the voltage when under load. (run jumper wires from the + and - of the battery bank. If it is a 36 volt cart and the voltage drops to below 36 volts, you do not have enoug current to run the cart. Plug in the charger and watch the ampmeter. If it goes up to about 20 amps, then it is charging. It should take a good charge after 10 hours. If the cart charges and only runs a short distance, the batteries need replacing.

You have the motor hooked up in reverse, you need to switch the two wires leading to the motor in order to fix it.

it sounds like you have a bad push button . if the wires where crossed you would most likely have this problem as soon as you turned on power .
