No Click No Go Wiring Problem? '91 EZGO
Hello, new member here, thanks for having this great forum
I am new to carts and have a bit of a mess on my hands. I bought an old cart and have been slowly fixing it up. When I first bought it I installed a new set of batteries and the cart ran fine. It is a 91 ez marathon 36v I took the cart completely apart to work on body repairs. After reassembly and reinstall batteries I have the following symptom No Go No Click The pack voltage is 36.7 at the charge receipt. and at the + Post on the pack I have checked wiring using the solid state speed control version found here on the site. My problem is I seem to have a wire I can't find on the drawing. In the attached photo there are two wires, one large 10 Ga white. I believe this is high current supply to the FNR switch? If so then I believe this goes to the key switch ? The smaller blue 16 Ga with a white female spade on it in photo, I don't know what that is or where to connect it. I was hoping one of the veterans might immediately recognize that wire? I will say that I had to have the battery supports repaired and the guy used a stick welder on the cart. I am concerned that he may have damaged (spiked) the controller or the solenoid/resistor, but I am hoping against hope that this is just my error during reassembly. Thanks in advance Last edited by Autonotions; 11-01-2014 at 05:42 PM.. Reason: Poor Title |

Re: No Click No Go Wiring Problem? '91 EZGO
You battery pack is only about 60% charged, so the plates are sulfating as we speak.
Better put them on charge. But, 36.7V ought to be enough to get the solenoid to click. The blue wire probably goes to the keyswitch. That is what is shown on the schematic at least. Not sure what the white wire is doing there. A 10Ga white wire is typically used to connect positive terminal in the charger receptacle to the main positive terminal on the battery pack. Trace it out to see where the other end is connected. |

I recall Ezgo using a big wire to the key switch. Not sure what they were thinking?

Re: No Click No Go Wiring Problem? '91 EZGO
Thanks for the responses.
I put it on charge like you recommended Thanks I finally got serious and loosened the FNR switch so I could see what is going on. It all seems to now match the wiring diagram MS-4 white 10GA goes to battery pack BR-R (front closest to center) MS-4 blk/white go in a sleeve to the bottom of speed control pot MS-4 red goes to back up alarm MS-2 Blue goes to key switch MS-2 Red goes to resistor Still nothing no click or movement. There was a bad cable that ran from battery pack positive to back terminal on coil end was loose. I replaced that cable. Can anyone advise the trouble shooting process I should use? Again the cart was welded on (batteries were out at the time but not sure if he could have zapped controller while welding) |
