I added a second HPWC in my garage and want to set them up as master/slave. I have them both wired up per Tesla manual and the communication cable wires between them. When I power them up I get 4 red flashes on the “slave” charger. I am pulling my hair out because it’s all wired and set up properly. I have double checked the wiring multiple times. I have checked the rotary switch multiple times. I have quadruple checked master/ slave configuration but not having any luck.
I have even tried switching the configuration around and when I switch it I get the 4 red flashes on the opposite charger.
Setup as follows;
Original HPWC charger rotary switch set to A. Communication +/- wires connected to output.
Second (new) HPWC charger rotary switch set to F. Communication +/- wires connected to input.
Both chargers are Gen 2.
I’m at a complete loss. I cannot get one set to master and the second set to slave.
I’m hoping someone else has encountered this and can provide a solution.
I have reset both of the chargers multiple times and powered cycled them multiple times as well.
If I disconnect the communication wire and set rotary switches on each unit to A they will both charge fine. I simply can’t get a “slave” charger when setting a rotary switch to F.
I would really appreciate your help.
Thanks
