Gab said:Throttle is set to pass through mode.
On the diagnostics screen and I can see the INPUT signal voltages jumps like 0.5v by itself with no movement ( could this be feedback or noise? ), I had a look at the PLIM flags and their is NO limiting happening at this time, nothing is in Capital letters. Its flag is =awsvt, so since their is no limiting none of the gain settings will make a difference...
These look like the key observations and your conclusion about limiting seems exactly right.
Also - there is virtually zero possibility of feedback/noise on the throttle signal.
The fact that the input is fluctuating pretty much puts the CA in the 'garbage-in, garbage-out' role - particularly since you are in PassThru mode.
Neil's diagnosis about a poor connection seems the most likely - this might be an issue with the throttle connector pin fit/crimp or a soldered connection inside the throttle or CA.
CA regulator capacity may seem a little counter-intuitive - it has greater current capacity at lower voltages. At only 36V, the capacity is fairly large and not too likely to be a cause in this case. ....Always worth checking, but my money is on a simple mechanical issue.
