Gidday,
I have a 2.Something Cycle Analyst that I use on my elecric car via a shunt.
Has been all good until either:
a) I swapped the polarity of the current sense (was reading backwards)
OR
b) I drilled through the five core wire supplying CA with power, ground, I sense and both speed sense wires.
The symptoms are erratic current measurement in the range of +-0.6A when smoothing by 5, or +-2A when smoothing by 1.
I have grounded the I sense at the PCB with the same result.
Current sensing still appears to work albeit with a large amount of noise.
Any ideas please?
Hoping I have just popped a cap somewhere 8)
Cheers.
