Throttle response changed after increasing battery voltage

[TommyCat]

1.2 volts on the throttle signal sure is an odd place to get stuck... was it still able to move around when you're moving the throttle handle?

Just checking... from your perspective CCW = throttle down, and CW = throttle up, correct?
Is this controller doing regeneration at any time?

Reset procedure is to rotate throttle to home or off position, then reapply to the power on area?
Does applying the brakes reset it?

The go pro is fine, but I don't want you to get too distracted from driving!
Tape up those testing leads better too...

That's the voltage (that I think I saw from a quick glance) when I got no power as I gave throttle input.

Correct

Is this controller doing regeneration at any time?

No regen

Reset procedure is to rotate throttle to home or off position, then reapply to the power on area?

Correct, that's the only way to get power back.

Does applying the brakes reset it?

You mean apply brake while holding current throttle position? That'd be hard to do for me (I do not have big hands or long fingers). If you are suggesting the brake signal may have been inhibiting the throttle, I've thought about that also. My hunch is that's not happening. To rule that out I need to monitor the brake signal (using an LED).

Edit: would using an LED to monitor brake signal be easy to rig up?

Gopro lessens distraction (do not have to watch DMM anymore). When it happens, I'll curse, that'll be the cue during video playback.

Not every wire is taped (3 throttle wires brought out) to make switching DMM connection easier. Nothing can short (the way it is) if an alligator clip falls off. I'll take your advice and tape it better.

Yes.
