1995 Medalist? (series motor)
I know I've been posting a lot of questions, but I'm new to carts and so far I've really been helped out a lot along the way and it's greatly appreciated. I finally got all the wiring straightened out (at least I think) and I hooked up 36 volts to the cart from my sons electric dirt bike batteries. it has three 12volt 12ah batteries. The solenoid clicks as soon as I turn the key on, but when I press the throttle, the tires move a little bit and then stop, it's the same thing in reverse. The reverse buzzer comes on. Is the solenoid supposed to click when the throttle is pressed down, because it isn't? Could it be that the small amp hour batteries just don't have enough power to make the motor spin? Any help would be greatly appreciated.

Re: 1995 Medalist? (series motor)
Okay, I did a few tests. I'm getting pack voltage to the battery side large terminal of the solenoid, but I'm also getting the same reading to the controller side large solenoid terminal (resistor installed) no drop in voltage. If I disconnect the resistor, I see about a 3 volt drop. With the key on, my battery test lead from my DVM on the main battery pack negative and the red test lead on the small solenoid terminal with the red wire, I have full battery pack voltage, but as soon as I press the throttle, It goes down to about 20 volts. Again, I'm not sure if this is because of the small 12 volt batteries or if there is another issue.

What is the 3X12V 12AH battery pack voltage before you press the pedal?
What is the battery pack voltage after you press the pedal? The 12AH battery pack probably won't move the half ton cart. Lift rear tires off ground (put on jack stands) and it might have enough oomph to turn the wheels when they are in the air. |

You either have a bad throttle microswitch, or the 4 wire Molex connector that connects the wiring harness to the throttle box is bad/shorted.
Solenoid should NOT click when you turn on the key with no throttle. Actually, it's also possible the pedal isn't coming all the way up. The easiest test is simply raise the pedal. |

I'll have to check the pedal later. Taking my son to a party. Thanks for all the help. |
