TL;DR: Read from "The acutal issue"
So yesterday I got a package. It was my brand new (used before, but brand new for me) FocBox 1.6.
I soldered new wires, bullet connectors and XT-90 and everything was working like it should. I did the setup with the following settings:
- Motor max: 70A
- Motor min: -60A
- Battery max: 45A
- Battery min: -15A
Today I went on the first test ride. Pumped up and ready to shred. Everything went fine the first kilometers. Temperature was maybe a bit high (60C at max). Then I came to this long long long road where I went nuts. Full throttle most of the time, 45 km/h most of the time and temperature eventually got higher. Temperature reached 70C (probably 80C but I had put my phone down in my pocket so I wouldn’t crash doing 45 km/h.)
So I eventually reached a light signal and had to brake. I braked pretty hard and at some point I noticed I had lost my brakes completely (unfortunately at low speed…). I went on to the side walk to test my accelerator and nothing happend…
I had no choice. The time was now. I was the chosen one. It was time for
AN ANTI-PUSHER TO BECOME A PUSHER. THE WALK (ACTUALLY PUSH) OF SHAME
I eventually made it home after 5 km of hard pushing without dying or killing my board even more (accidentally pushed my board out in the middle of the road (no cars, unfortunately)).
Time had come, now I had to open my enclosure and focbox. This video speaks for it self…
As the video showed, no damage on the pcb.
Now to the actual issue:
- My FocBox doesn’t turn on (No lights or anything)
- My PC doesn’t recognize my FocBox when I plug it with USB in and give it power.
- I can read 39V power when measuring Focbox negative on PCB and battery positive.
- I can read 5V from the UART port when the focbox is getting power.
- Since I can’t turn on my FocBox, I can’t check the terminal for any error codes…
- Single motor
- No can-bus used.
I would appreciate if someone had any suggestions on what happend. Like usual, any input is appreciated. Also the bad ones
