new controller and new solenoid still no go!

He says he's tried a known good motor. It ain't gonna run at 33.x volts.....

Oh sorry forgot to say that i have a new pack of batteries with all new 2 gauge wiring and full pack voltage was at 41v in my last post but that was right after i unplugged it and yes the motor is known good off my 2001 ezgo.

Any have anything else?

If the solenoid is clicking when it is supposed to be, go back to my Post#4.

Measure and record the pack voltage.

Connect your voltmeter test leads between the controller's B- and M- terminals.

If you have a pre-charge resistor on the solenoid, you should read a couple volts less than the pack voltage.

Press pedal just far enough for solenoid to click. You should now have FULL pack voltage.

If you don't have full pack voltage, trace the high current path through the cables, connections, contacts and components until you find it.

If you do have full pack voltage, press pedal to floor and the voltage between B- and M- should decrease to Zero, or very close to it.

If the voltage does not decrease to zero, check the throttle input to controller.

If throttle is good, the controller is bad.

His post #4 said the above. FWIW.

When should the solenoid click only once when u turn key on or every time u push the pedal?

[larryo587]

The solenoid clicks when the key is turned on but not when the pedal is depressed

It would seem to me that if your solenoid clicks when you turn on the key, then you have a problem with your ITS system. (Your gas peddle is not working properly) So, you either need to adjust your ITS, or your ITS is bad.

That's my take on it. Your solenoid should not click on until you depress your "gas" peddle.

Thought so ill see if i can fiure out whats up with it then get back too yall if thats not the fix

I'm certainly not a Marathon expert, but if you download the wiring diagram, you'll likely see the FNR has the be in F or R (not N), keyswitch on, pedal pressed, and charger not connected, before the solenoid clicks. Likely one of these is shorted.

If this is a resistor cart, check the contacts.
