What is my problem

72v is an unusual voltage for a regular cart, sounds like you may have a lot of mods or it's a 36v cart and you are thinking your 6v batteries are 12v.
Start by confirming the cart voltage, what is the total battery pack voltage?
Is this a series cart or a PDS?
There about 7 wires going to the controller, which one gets hot?
The loud bangs are from what area?

I have 9 8 volt and 1 12volt to handle the accessories. there are 4 wires going to the controler I bought the cart from a client The bang is comin from the back . when i put it in gear it wnats to go even though i dont totouch the peddle. No cart shops want to touch it because its 72 volt It does have a 48 volt solenoid but i can still here it turn on and off. No shops can find a 72 volt solenoid. I have had it for 7 months and drove it for maybe an hour.

How do i tell what cart it is. If someone could even call me that would be great I can send pics to your phone. 843-503-6273. Thanks Jamie.
If the cart runs it is likely not a wiring issue.
The fact that it is moving without touching the throttle indicates the solenoid is likely stuck on, this will make wires hot. I would change the solenoid as it sounds like the culprit. You don't need a 72v solenoid, just short wire it to a 48v source (6th battery). I have a 42v cart (7x6v batteries) that uses a 36v solenoid short wired to a 36v source (6th battery).
The banging is changing from F to R with power applied to the motor. That should go away after the solenoid is fixed.
Post up some photos of the battery compartment and the controller.

I will try the sylanoid. what type do you recomend.and where can i get one .does a auto parts store carry them. how do i tell what series cart i have.
Do not use an automotive solenoid, they are not rated for continuous duty. Get a HD one for a golf cart. Try one our sponsors, they all carry them.
A series cart is the type of motor, there are 2 usual types, series and sepex.
What year is your cart (mfg number), do you have a run/tow switch under the seat on the controller, and where is the F-N-R switch located?

I will try to get some pics on today of my cart. My controller has 3 big wires and 3 small wires the small ones go to the potentiometre pin 2and pin3 are the only ones hooked up.The green and blue are not hooked up.The large wires from the motor are s1,s,a1,a2 .If you look at the back of the f and r switch that is where all those s and a wires are going. i dont know if they are in the right spot. Or if they are in the right spot on the motor.

If my cart is 72 volts is it ok to have a 36 volt motor
