Ezgo 48v charger receptacle grey wire

[gobgolfcarts]

I have a 2012 ezgo txt. The grey wire coming out of the charger receptacle connects to the main +. The terminal on the end of this wire was corroded. I cut it off below the black square box on the terminal. Once i cut it, i realized there is a black and red wire inside of the grey(wire) insulation. Can i just splice these wires together, put a terminal on it and go on my way. Or did the black box that these red and black wire go into, hold some kind of significance?

The charge rate of the Delt-Q charger varies in accordance with the battery temperature and the "black box" at the battery end of the gray cable is a temperature sensor.

IIRC you have to put a fixed resistor between the red and black wires to get the charger to work (at a fix charge rate), but I don't remember how many Ohms the resistor should be.

Otherwise, you have to replace the charge receptacle. $$$

You have 2 options, rig it with any 10k ohm resistor. Or, fix it right with a new sensor, see below for part number. You could also buy a whole new receptacle, but you don't really need the whole thing in your situation.

Oooops! I wasn't aware that a new sensor only was available. My mistake.

Thank you guys. bought a resistor today. works well.

Where did you order one from?

Just Got my txt today and I am working on it.
The charge port was not hooked up. There are eyelets on the small black and red wires that are in the grey insulation. From what this thread is saying that is not right.

I need to put a 10k ohm resistor between the red and black wires?

That'll work fine. And the red & black wires are not supposed to actually get any power from the battery post, just measure it's temp (this is why the temp sensor could be put on any terminal). In your "resistor bypass" setup, don't put it on a battery.

Thanks CG
When I hook up the charger it flashes the red light once which indicates battery temp fault.
Which is correct

I’ll get a 10k ohm resistor tomorrow and put it between the small red and black wires.
Hopefully with the previous owner hooking them up to the battery terminals did not damage the charger

Found a 10k ohm resister and wired it in. Charger works great now!!

Thanks cg
