1995 DCS EZGO wiring troubleshooting
Hey guys wondering if someone could send me the info for testing the wiring and motor on a 1995 DCS EZGO 36v.
I cannot seem to get the Solenoid to click without jumping the negative battery terminal to the blue wire from controller. I have removed motor and confirmed it was a DCS motor and tested the ITS and switch. Looking for info for testing the armature on the motor and what each pin on the harness should test and when? Currently I have 36v on both sides of solenoid without click? is that correct? |

Re: 1995 DCS EZGO wiring troubleshooting
Which type F/R switch does your cart have? Attachment-1 is early 95 and Attachment-2 is later 95 to 99.
In either case, with Run/Tow switch in Run, F/r in either F or R and Keyswitch ON, you should have battery pack voltage (38.2V for fully charged) on Pins 6, 7, 9 and 10. When you push the pedal, you should get battery pack voltage on Pin-5 and Pin-7 ought to drop to 0V (B-), energizing solenoid. |

Re: 1995 DCS EZGO wiring troubleshooting
Its is an early 95 style.
I do not have pin seven dropping to 0V when the pedal is pushed. I have tested switch in pedal control and it does not allow 38v with pedal not pressed and allows 38v with pedal depressed. I will check all voltage when i get home and let you know. |

Re: 1995 DCS EZGO wiring troubleshooting
IF it turns out to be a bad controller, do not install another stock controller.
The Curtis 1206SX (stock DCS controller) was EZGO's first attempt at a sepex drive system and the controller was flawed design and fails often. Replace it with an Alltrax XCT48400-DCS (or larger), which is user programmable. ------------ When the blue wire on the solenoid is jumpered to B-, getting the solenoid to click, will the cart run? --------- Here is a schematic for your cart's drive system. |

Re: 1995 DCS EZGO wiring troubleshooting
When I put negative directly to blue wire, cart will run in forward ( sometimes) but not in reverse
you can hear it trying but it does not spin all the time in forward. I have to switch the FR switch a few times for it to spin full out. Also unfortunately I purchased a refurbished controller already and am having the same issue. I was told if the blue wire doesn't pull a ground, then the controller is bad. |

Re: 1995 DCS EZGO wiring troubleshooting
If you have pack voltage on Pins 6,9 & 10 and Pin-7 does no go low when Pin-5 goes high, the controller is bad.

Re: 1995 DCS EZGO wiring troubleshooting
I bought a 500a Alltrax controller and the solenoid to go with it and am really happy with it (I have a 1995 dcs also). But I have 2 of the Curtis controllers you are welcome to. I honestly have no idea if either of them work though. I never even tried them. I know the harness was melted on one of them. Not sure where you live, but I’m in Louisiana and you’re welcome to them if you would like them. Just thought I would offer.

I sent you a pm
anyone have an idea of how that resistor and diode set goes on solenoid? or does direction not matter? |
