Oh ok, well I would just be speculating because I do not have any technical documents on the motors. But they are BLDC, brushless DC motors. So they should have 3 channels for power in and then usually about 5 lower current pins for the hall effects (power, hall A, hall B, hall C, and ground)...

I guess I am wondering what makes you think your batteries are bad/need to be replaced.

JD22 replaced a battery and they did not say any special process was required.

It is not possible to get the full functionality of this mower without all CAN devices connected. Battery 1 provides a terminating resistor, so without that the whole bus will have issues, if it runs at all. Also just an FYI, the 12v does not technically come from the battery, it comes from the...

I would recommend providing a bit more context to your issue so people can better help you. I assume the wire colors you are asking about are from the batteries. Blue and White is CAN, you are going to have a hard time reading anything of value with something like a DMM, if that is what you are...

Well, the great E325 error saga of my LT42E turned out to be about as dramatic as a soap opera with a 5-minute runtime. I was ready to bust out the multimeter, start whispering sweet nothings to the mower’s controller, maybe even call in a priest for an exorcism… but nope. Turns out one of the...

Have you downloaded the wiring diagram and error code list? I uploaded them as part of a thread on some of my repairs here: Thread 'The LT42e Chronicles: A Tale of Wires, Woe, and Mild Electrocution'...

I assume you aren't hearing the relay click when you insert the key, right?

Much appreciated for the kind words! I had to take a little breather after the wild ride this mower took me on — it was equal parts wrenching and therapy 😅 But I’m back, and wouldn’t you know it, the saga continues… This time it’s the infamous E325 error: the dreaded right motor hall fault...

Did you look at the wiring diagram I posted? That at least gives signal names for the battery pins. But if I was a betting man its either pin 12 tells the battery that the VCM key is installed or its a wake on CAN situation. I was told by someone very close to the development of these batteries...

E111 is a VCM internal fault. It means the VCM failed its internal test. Unfortunately that is all the data that the VCM code sheets says. Did you review the 56V Electric Zero Turn Troubleshooting guide? That walks you through some initial steps, all three versions of these mowers are very...

Wow, you have really dove in! I appreciate the initiative and good luck on your goal, let me know if I can help. Not sure about your system, but on the newer the motors themselves also communicate over CAN. Really the only thing that does not communicate over CAN is the PDM, brake switch, TPS...

The motors are most likely DC motors. The motor controllers will drive a square wave to alternate per phase of the motor based on the speed input provided. Obviously the blade motors will be driven at a constant speed and the drive motor will be variable. I guess your model version has some more...

I would be reluctant to do that, easy way to cause a catastrophic failure of your batteries and start a fire if you are not careful. Does your VCM turn on at all? It is odd that you are getting an error code on one thing but not the other.

I believe that is the PDM (Power Distribution Module). Your earlier system looks a bit different than mine, but I believe that is it. That is what houses the contactor that gives the "click" when the VCM (Vehicle Control Module) says everything is good. If you have error codes, most of the time...
