1990 Wire Diagram Marathon Search
hi I posted but someone deleted my post I guessing cuz I posted the diagram off your own website but here I post it again
I did the search on the ezgo website with my serial number and got this, but it shows on the identity plate its Textron Model: Marathon Type: Electric Sub Model: Electric 4-wheel Marathon Year: 1990 I contacted ez-go but they wont help me, they tell me goto a dealer and that I need special training to work on these I got this cart for free but its missing the major of the wires for the batteries and id like to know which wiring is right like a good drawing not what I seen where some wires covered up and you don't know exactly also I don't have 6 golf cart batteries to test this will it work on 12 volts? whats the voltage range for these as I have 2 golf cart batteries if it can be tested but a decent diagram would be great. and they wont even give me a diagram they basically make you buy the book so from the diagrams its the first one it looks like it but not really and the relay for it is hidden so I looking for an exact wiring diagram for this model and also how can u test the converter and the motor without 37 volts or knowing the exact wiring |

Looks like a Curtis 1204 controller. Here is a drawing showing the labels for the terminals.
Here is a schematic for a 1990 Marathon with a speed controller. The "Relay" (typically referred to as a solenoid ib golf cart circles) is the black round think with two large and two small terminals on top. |

Re: 1990 Wire Diagram Marathon Search
ok that is great thanks now couple questions
how do I know on the motor what side is S1 S2 and A1 A2 also this doesn't have a potentiometer whats that for? do you need it and what is the MS-3 |

Post a picture of motor showing the four studs.
The 0-5k potentiometer is the throttle. When you push the pedal, the mechanical linkage turns the potentiometer's shaft. MS-3 is the pedal microswitch. When the pedal is pushed, the lever arm pushing against switch button moves, allowing NC contacts to close, which in turn energizes the solenoid. |

Re: 1990 Wire Diagram Marathon Search
ok 1 I wish I knew if this site offers a setting that when you reply it emails me to say someone replied to this thread I didn't know you replied
I see u pointed them out I do notice a couple wires like 20 gauge wires cut off from the forward reverse switch what they be fore? Ill try to take a pic of the motor bt is there a way to test this the DC converter or the motor without hooking up the batterys and what size of nuts are those on the forward reverse poles and the solinode as they don't have them on there also the one pic said the Plug diode to motor what diode is that that's for the A2 I think |

a. Go to the first menu bar above where you are now reading and towards the right side, there is a selection labeled "Thread Tools". You can subscribe to the thread you are currently reading on the menu that drops down. b. Reply to a post by clicking the "post Reply" button at botton left, or by clicking the "Quote" at the bottom right of the post, or clinking on the "Go Advanced" below the Quik Reply window below. When you get to the fully feature text entry window, scroll down below the "Additional Options" and you will find a "Thread Notification" option. From the drop down menu, you can select various notification options that apply to all threads you post or reply to. 2. There are three microswitches on the F/R assembly. One is party of the solenoid activation circuit, one turns on the beeper when in reverse and the other changes the throttle from 0-5K into 0-2.5K for half speed reverse. The schematic I posted has the wire colors on it. 3. I suspect you are referring to the controller when you say "DC Converter" and the answer is NO for the controller and only partially for the motor. (Continuity test for windings) 4. I don't know the size, but I'm pretty sure the are Stainless Steel. (Corrosive atmosphere in battery compartment) 5. If an electric cart with a series wound motor is switched into into reverse while traveling forward, the motor locks up and the passenger is launched over the dashboard while the driver is impaled on the steering column. Plug braking slows the cart to a stop more gradually. The Plug Brake Diode is located inside the controller. |

Re: 1990 Wire Diagram Marathon Search
1. oh ok ill check that out after.
2nd ah ok ill have to look Im sure the wires are ripped off something lol but ill print off schematic 3. so hopefully one of these things is working as Im sure they wouldn't taken all the wiring off it it was working lol and might be cheaper to convert to gas minus u cant do reverse easily lol 4. ah ok and what is the size of wire you guys use for it is it 4gauge wiring? 5. oh so I don't need to worry about this plug diode then cuz from the schematic it basically shows it jumpes from one terminal to the next terminal on the controller that's why I was wondering if I needed to get it I see there is a diode on the solinode whats that one for? |
