Is there away to test controller out of the cart .also no light goes on the controller .

I posted a reply to the question you've asked in one of several of the old threads you've resurrected with the same question.

I'm not fond of the shotgun approach, so I'm not saying which one.

You pretty much need the whole system to test the control. You may as well put it back in the cart and charge the catteries. This is where we would like to start.

EZGO Diagnostic testing for Ezgo Solid State speed Control Systems

Testing of the EZGO ELECTRONIC SPEED CONTROL - SERIES Drive system.
ALWAYS DISCONNECT THE NEGATIVE BATTERY CABLE BEFORE REMOVING CONTROLLER COVER. RE-CONNECT CABLE AFTER COVER IS REMOVED.
These tests are to be conducted after making sure all wires and cable connections are clean and tight.
Battery pack MUST read 36v to 38v
PLACE THE REAR OF THE CART SECURELY ON JACK STANDS FOR SAFETY
Connect (-) probe of meter on Battery Pack main Negative (-) post. (This probe will on the post for the rest of the testing procedures) Connect (+) probe to the Battery Pack Positive (+) battery post. (This reading is the Battery pack voltage and is often referred to as pack voltage.
NOW, Key switch ON, gear selector in FORWARD, Place the (+) probe on the battery side of the solenoid's large post (If the reading is below battery voltage, check cable connections between solenoid and Main (+).
Place the (+) probe to the controller side of the solenoid's large post. With the resistor in place the reading should be 0.1 to 3 volts less than battery voltage. If the reading is more than 3 volts less the battery voltage, the resistor is faulty. If the voltage is the same as the battery voltage, replace the solenoid.
Solenoid test is done with the resistor removed from one large terminal. You should always have pack voltage (+) on the side connected to the batteries. When the small terminals have (+) and (-) to them the solenoid should CLICK and pack voltage should be present at both large terminals. If no, the solenoid has failed. If (+) and (-) are not present at the small terminals when the pedal is pressed, a problem exists within the solenoid activation circuit. This circuit consists of a series of switches and is easily traced using the solenoid activation circuit diagrams available on the forum. The switches are activated in this order: Reed switch – F&R micro switch(ms) – key switch – Foot or pedal box switch. All of these switches must work before the (+) side of the solenoid activation is delivered to one of the small posts (red wire)
