Electric help needed 1995 medalists

[mooneyes]

Hello everybody I picked up a 95 medalists 36 volt everything was working great until yesterday got to camp buggy fully charged took a little spin went to go again nothing I checked for loose wiring corrosion everything looks good checked battery pack getting 37 volts here's my question should the solenoid click when I turn the key on never noticed it before I hit the accelerate pedal I get nothing nothing any help would be appreciated thank you

The solenoid should click when the key is on and the cart is in gear and the gas peddle is pressed. Check the gas pedal micro switch for damage.

Give all the cables a tug & twist at every end to see if you have a weak or broken connection.

Thanks scottyb is there a micro switch under the cart I took the floor mat up and found a sensor but no micro switch

It is (or should be) in the same box as the ITS sensor.
The Red and Green wires in the picture attach to the pedal microswitch.

thanks johnnieb this is what I found iguess someone bypassed the micro switch is that a bad thing

Yes - that is the power on for both controller and solenoid. If they are left on when the cart is not running it will shorten their useful life.
All for the lack a $15 pedal micro switch.

Yes, it is a bad thing and ought to be fixed.

However, that isn't what is keep the cart from running. It may caused whatever failed to fail, but the cart had been running with the pedal switch bypassed until it stopped yesterday.

Is it a Series drive or a DCS? (If there is a Run/Tow switch on controller cover, it is a DCS)

You said the solenoid clicked, so the problem is in the high current circuit.
This test will work for either type drive system:

Put rear of half-ton cart on jackstands so it doesn't take off unexpectedly and run over someone or something.

Connect your DVM between the M- and B- terminals on the controller.
After the solenoid clicks, you should measure FULL battery pack voltage.
If so, push the throttle pedal and the voltage should decrease to zero.

Need to know which drive system to troubleshoot further.

BTW: You battery needs to be charged, 37.0V is only 67% SoC.

thanks for the info johnnie b and scotty b looking at the wiring diagram in the sticky my cart does not have a diode or resistor on the solenoid should I add them and is there a spec on what to purchase again your knowledge means a lot to me

[JohnnieB]

For a 36V system, the resistor should be about 250 Ohms, 10W and the diode should pass an amp or more.

one other thing I noticed in your picture of the pedal box.....there was quite a bit of water in the box.....keep it as dry as you can.....seal it.
