Sorry if I'm frustrating you, I am lacking confidence you're putting things the right way around. I don't mean to speak down to anyone, so if you take offense at this - my apology. I'm not here to insult anyone; I just want to be absolutely certain you have this the right way around.

Based on your description you are saying the dashed wire is the negative lead from the power supply. According to the drawing you drew you have the diode going from positive to negative, creating a short circuit. The relay wont work, the diode will burn out and possibly the supply will be damaged. And quite possible the floor switch will also be damaged. The drawing I've attached should make it very clear as to which way the diode goes. Beyond this I'm not going to be able to help you. By now you should have enough information to handle this correctly. Again, if this comes off condescending - I apologize.

 

Also putting a extra diode (oriented correctly) In the positive lead before the relay, will prevent problems when hooking up power supply by others. The circuit/relay would only work when power is correct and wouldn't work if wrongly connected. (as I posted in post #7) Just an extra precaution, or as it's know "idiot proofing".

Excellent point. Even I couldn't screw that up.

 

Shortbus suggested this mod and I agree with it. And now I'm done here.

 

Haha @Tonyr1084 I appreciate your being worried - I am a total amateur obviously!

Thanks for the clarification.

Please see the image attached - I will be wiring this up today so let me know!

The PSU will be hardwired so while I like Shortbus' suggestion, I don't think it will be necessary.

Thanks!

Guys! It works! Check out the most unexciting attachments ever to be posted.

Note - extra diode was just to test my soldering skills

Thanks for all your help guys!

 

And all closed up

 

Which circuit drawing software are you using? Your drawings look great!

You must be asking @Tonyr1084 ?

I just used illustrator

What would be a good electronics drawing package? Anything you can test on? I remembered doing that in engineering. Was called electronics workbench or something?

 

Which circuit drawing software are you using?

Don't use any software. I use paintbrush.

If you're asking me, thanks! I draw the schematic with LTspice, convert the image to a bitmap, edit it with Paint and save it as a .png.

 

Thanks to @Thenextman , @Tonyr1084 and @EM Fields for the feedback. I was directing the question to EM. The circuit drawing at the end of this thread was nice and I'm looking for a way to produce drawings for my techs when we do custom installs of refrigeration controls.

Agreed - it is a lovely drawing. Extremely clear. Same goes for Tony's
