receive +12 over tJust think about it, I have removed my solenoid and it only has a single conductor... and it bench tested just fine when +12 was applied to the wire and the solenoid's body was connected to negative. It is my belief that any electrical component with a single wire should hat wire... unless the component is somehow isolated from the car's chassis!

Sam,
What you did above, is the same way the kick down solenoid works in this car, which is a simple series circuit

Those 13.86 volts did its job by energizing the solenoid coil (load), as it leaves the solenoid body (the ground side in this circuit, its not 13.86volts, that voltage was used up by the coil and wires, the load, the voltage returning to the negative side of the battery post in know 0.12


Picture 2, channel 2 is the voltage into the KD solenoid, 13.86 volts is power flow to the solenoid

Channel 1 is the KD solenoid ground side. 0.12v is the voltage dropped by the load, ground side.


I hope this explains what I said. Automotive electronics was and still is my weakest subject in school, many, moons ago.

If I can word it another way... your Snap-On analyzer's 0.12 V reading is telling us the voltage difference between the ground of the battery [ zero or zero reference ] and the grounded body of the solenoid and the transmission to which it is bolted [ + 0.12V ].

If I am correct in putting it this way, then I understand it.
Right?
