Install that DIN Plug back into it’s home and retrieve the other part of this puzzle needed.
The chart jrj provided (above) shows there are color codes associated with that audible warning beep.
What color was it blinking?
It is blinking yellow. I unplugged the DIN connector and charged the batteries. Now that the batteries are charged the immediate problem is patched. With the batteries charged I can reconnect the DIN plug until I replace the sensor or until I need to charge the batteries again, whichever comes first. The sensor looks about how you’d expect something that has been rolling around the battery box for nearly 20 years to look.
Since you aren’t really using the temp sensor you could try cutting it off and wiring in a 10k resistor in it’s place.
That should keep the charger happy.
That’s the sort of thing that I might consider if I even knew what it meant. My level of comprehension is near zero. Meanwhile I have ordered a new assembly through Electric Conversions ($58 plus tax and shipping).

Ah, That’ll work too.
Sometimes the gang here will go all techy-geek assuming the other person also knows of such voodoo and magical things.
If you would like to learn, feel free to ask. If it is just beyond your skill set and you are fine with that, it is OK too. We just figure out another path to your solution.
If you want to see how complicated that temp sensor is then have a look at what I found and how I fixed my 2002 when the same thing happened.
Yeah, but you know which end of a soldering iron to lick…
Try licking one end and if it feels good you hold that end. 50/50 and away you go.
Yeah, but the one that stings a bit tastes better.
Hi,
I have a 2002 E825. When I plug in the charger, the dash blinks red and I get a two tone beep. It doesnt charge. The batteries all test pretty even with the pack voltage is 72.3 volts. I have unplugged the din plug on the top of the Zivan charger and it still doesnt charge. The batteries are 2 years old. My battery disconnect is on green. I have this car for a few months and it was charging fine…until.now.
Not sure if you know this but 72.3V is only 12.03V per battery and that means all of your batteries are at 0% State of Charge(SoC). If your battery temp sensor is failed, the zivan should still charge when you disconnect the Din plug but you won’t see the LED blinking.
But if you pull the DIN plug and your Zivan is properly wired, it should be charging. I would look at measuring the battery wires going into the Zivan( I think it’s the larger plug and there should be room for you to probe your Volt meter into the back of the connector). Obviously you should see the same voltage you see when you measure across all of your batteries.
Also, are the 2 wires connected onto the spade lugs( red and green wires)? see this trouble shooting guild and you don’t want to leave your batteries at 12.03 v for long. Lead acid batteries need to be kept fully charged when not being used or else the chemistry starts breaking down and capacity is lost forever. Troubleshooting Zivan NG1
