Hi Brains Trust,
I have a Z1k LV.
My hairball gives me errors 1141 and 1124 when I try to accelerate in any gear
(worst in 5th, and least bad in 1st)
The manual tells me 1141 is contactor high resistance. my DMM measuring the
voltage across the battery and controller inputs to the hairball puts the
voltage drop at 15mV for 100A (battery amps that is). Which looks about right
for a good contactor
The contactor always drops out when I turn the ignition off, and my DMM
measures 92v across the contactor (measured at the hairball terminals). My
conversion is 96v nominal (actual battery voltage is 102v, though the little
white light on the hairball must act as a voltage divider, dropping 10v)
I opened the hairball, and it looks clean inside - nothing looks damaged
visually.
Any ideas on what to check next?
Is it possible to see what the hairball is measuring as the voltage drop across
the contactor?
thanks in advance,
Matt

Isn't that how a plasma cutter works?

This is highly simplistic, and really not very accurate . The formation of
ozone in the atmosphere is much more complex than that, and results not from
“other pollutants” but hydrocarbons or volatile organic gases. The amount
produced, if any is highly dependent on many factors.
And ozone itself is not particularly stable.
There may be a lot of NOx produced, and NOx is a pollutant itself. But it is
possible that any emissions can be controlled.
If you are talking about plasma (which we are), ozone can be directly produced
from that, though I am not familiar with the chemistry.
