Found the needles, have some jumpers ready and a long one for the proper ground so as to use 2 probes at once.

I know and we were still getting acquainted...and a couple times I probably overdid the background and appreciate Moderator deletion, at my request. At the risk of perhaps having to again do so, I will share this:

In 1985, I was asked for input on an automation project, for which I sold the DC motor, gear reducer and brake.

The machine, one of many built by Calmation's predecessor, inserted .025 square pins (bandolier fed) into an AT&T backplane at the rate of 20 pins per second: 5 pin head, dual heads, 2 insertions per second.

The challenge was to increase speed, but when motor speed was increased, the brake (sensor activated for positioning) would overheat and cause position drift. A larger brake would dissipate the heat, but created an inertia problem and advancing the timing of sensor activation was inconsistent.

My solution was not at all technical: I simply suggested blowing air on the brake to prevent overheating. It worked...and was not previously discussed in either Warner (electric clutch/brakes) nor Horton (pneumatic clutch/brakes) factory technical seminars.

The moral of this story is to recommend not overthinking a problem or its solution.
Correction
I forgot about DTC 29-1, which is most likely connector or wiring issue, not a positional error.
I would correct post 1042 and 1047 but too much time has elapsed for me to do so.

Doc, What do you want the posts to say? Ferret or I will edit them for you.
