I wish I could get my serial communication problem solved, I currently
can't talk to the hairball at all.
Sounds like your Hairball is damaged. I killed mine once. It would
communicate intermittently, then stopped talking at all. Do you have relay
anti-kickback (snubber, flyback) diodes across your 12V relays as Roland
suggested? When mine died it was the serial comms and precharge that
failed. Apparently they share a driver IC that I somehow killed via the
precharge circuitry.
I have an LED dome light in my car, so if I forget to put a diode across a
relay's terminals I'll see the LED flash at night when the relay turns off.
I have check my throttle resistance It is 400 ohms to 5,200 I checked
that is within spec. At 2,000 ohms I get a bit of drop out but nowhere
else in the throw.
Maybe I should replace the pot?
You can always put a jumper lead across the pot and see if your vehicle
starts.
I don't believe that I should have updated my profile while the car is
in go mode, I noticed that it kicks off its contactor when a new
profile is sent (this was while charging)
OK. You mentioned updating BMS. Didn't know you were talking about setting
Zilla parameters. Don't know if this has anything to do with your problem
or not.
HTH,
Adrian
