Nothing should connect to TB1 pin 5 (VIN)

VFIELD (TB1 pins 1..4) is where +24V power goes

Sorry PCW, did not notice that in the other topic, or this one or ...

Now I am really confused. I connected the power based on this schematic. Is this not correct?

I am truly confused, what is different on my drawing vs Norbert's... besides the terminal block between the power supply and mesa board?

I'll leave others confuse you about the power connection.

So back to your diode. It might be easier to use discrete components so you can just wire in to the solenoid terminals directly but if you must, from your diode block, pin 2 would be connected to the red wire where it attaches to the solenoid and pin 1 would attach to the other solenoid terminal (black wire).

If you used a discrete diode, you would just bridge the solenoid connectors using the diode with the solid band pointing back towards the output.

Did it look out of whack to you? I have been looking back and forth between Norbert's drawing and mine and it looks the same. I feel like I'm tripping.

Ok, so I am making this harder than it needs to be... I do that quite often. Would you mind posting a link or part number to exactly what you are referring to, 'discrete component'? Thx
