1993 E-Z-GO Marathon "Freedom" throttle Issues
Hello everyone, thank you in advanced for your help and suggestions.
I have a 1993 EZGO Marathon "Freedom" model (SN #: 676514) The cart is in virtually mint condition. I've just installed brand new Duracell GC2 6-volt batteries, but when I am riding it and try to go full throttle is stalls. I can go about 70% speed and go about 16 mph, but once I push any further, the motor just stops. The cables aren't the greatest and already put in an order for new 4-gauge cables, but I am not thinking this is whats causing the problem. Am I looking at a solenoid issue? Motor issue? Or? Would greatly appreciate any suggestions / advice. Additionally, I am looking for a new horn and front lights for this model, can someone point me in the right direction for some aftermarket lights? I only need the lights/wiring, the front base is in great condition and the rear lights are working fine, but I may want to upgrade those to LED. Thank you, Mike C. |

Re: 1993 E-Z-GO Marathon "Freedom" throttle Issues
I haven't received the new cables yet (4g), would you suggest cancelling this order and going with 2g better? But I've tried cleaning the contacts as best as I've could on the current (6g) cables. I will definitely try to clean the contacts on the FNR, any specific way to do this that you would suggest? Should I apply some type of electrical grease or the alike after cleaning? Use alcohol to clean contacts or possibly rust removed if there's any surface rust?
Thank you very much for the help! |

Marathon = 0-5k throttle. Unplug controller pins 2 & 3 and test those 2 wires with ohm meter set to 20k ohms. I bet your throttle is going over 5k when at full throttle. Lucky for you, they can often be adjusted back into range. Search "adjusting PB-6 throttle".

Re: 1993 E-Z-GO Marathon "Freedom" throttle Issues
Thank you guys for the help. My multimeter is dead, but I cleaned the contacts for the FNR and put on 2g wires I forgot I had. Now it runs to 70% then just stops running between that and 90 and kind of choke cruises between 90-100%.
I have yet to be able to check the controller pins, but gonna try to tonight. |

Re: 1993 E-Z-GO Marathon "Freedom" throttle Issues
You are testing the wires that plug into the controller pins 2 & 3, not the controller pins themselves. Sounds like a bad throttle sensor.
