2012 ezgo 48 volt charger receptacle

[ron67601]

My power wise QE charger flashes 2 red lights then pause and repeats. My battery pack voltage is 51volts at the batteries and at the receptacle. What does the third wire do in this receptacle? I undid the black housing on the wire and checked continuity from receptacle to the one end and got a buzz but not true continuity. Could this be the problem and what is this? Thanks. Ron

3rd wire tells cart not to move cause charger is pluged in

Powerwise QE and Delta Q Charger Fault Codes

LED OPERATION CODES:
SHORT GREEN FLASH = less than 80% charged
LONG GREEN FLASH = more than 80% charged
SOLID GREEN = 100% charged
RED FLASH = fault code

LED FAULT CODES:
RED FLASH: Light turns on briefly, but does not
flash after that – check for valid AC voltage.

ONE RED FLASH: One flash, a pause and then
again one flash and a pause – Charge Enable
Fault: poor contact in the DC connector or dirty
contacts or Battery Temperature Fault: battery
temperature is greater than 122° F (50° C) or less
than 14° F (-10° C).

TWO RED FLASHES: Two flashes, a pause and
then again two flashes and a pause – Battery Voltage
Fault: Battery pack is less than 36.0 Volts or
more than 67.2 Volts. Battery pack is too discharged
or over charged for the charger to work.

THREE RED FLASHES: Three flashes, a pause
and then again three flashes and a pause – Battery
Charge Time-out: Charge time exceeded 24
hours. This may indicate a problem with the battery
pack or that the charger output current was
severely reduced due to high ambient temperatures.

FOUR RED FLASHES: Four flashes, a pause and
then again four flashes and a pause – Battery
Fault: Charge time exceeded. This indicates a
problem with the battery pack voltage not reaching
the required nominal level within the maximum
time allowed.

SIX RED FLASHES: Six flashes, a pause and
then again six flashes and a pause – Charger
Fault: An internal fault has been detected. If this
fault is displayed again after unplugging the
charger’s DC power cord and plugging it back in,
the charger must be taken to a qualified service
center.

Could it give me the two flashes of red? The cart does move but why does the charger think there is a voltage fault? Voltage is fine.

those chargers are crap (imho)
check again on flashes

The charger works fine on another cart that I hooked it to. I think it has something to do with the 3rd wire and that little black connector in line with it.

if you think so

Thanks for your knowledge. Lol

Does anyone have the answers to my questions?

Grey wire is Temp sensor
Red wire is B+
Black wire is B-
Blue wire with connecter is cart enable.

As C.T.D. said please confirm flash pattern as fault indicated has nothing to do with
grey or blue wire.

P.S. dont piss off CTD, he looks like he could kick your butt.
