Pinranha mini pin going from virtual to full feedback. Need help with relay wiring

[arcadepcnut]

Hello all. Got everything ready to convert my virtual pin to LEDs and feedback with contactors. Also read the pinball 101 document and sorta have a handle on things. But I've got a few questions, I have a 12v supply for the LEDs. And a 24v supply for my 7 contactors and my knocker. The contactors I understand can run directly off the ledwiz and no need for a relay?

My main question is how to wire the knocker. The knocker I know for sure I need a relay. I'm using the standard car relays. 87 87a 30 86 85

I'm just not sure how to wire it!

It has the pins 30 which I think goes to my 24v power supply directly. 85 goes to ground. Here is the part I don't know. Does 87 or 87a go to the knocker? And 86 is my trigger from the ledwiz?

Please help and offer some pointers. Will my 24v contactors need relays? I read they can just go one pin ground and the other 24v through the ledwiz so there is no lag. Wiring The relays confuse me.

can someone please assist or point me to a forum or post?

 

Here are my components:

24V power supply

ledwiz

24v real pinball knocker

car relay

 

Here is what I THINK in need to do. Can someone please confirm or deny before I burn something up? I would like to get started on this on the weekend and need to map this out in my brain before I start.

 

ledwiz to 86 on relay, 85 to common ground, 30 to 24v power supply, 87 or 87a to real 24v knocker.

 

or better yet a picture.

Pin 85 should be +24VDC. The ledwiz wire on pin 86 is the ground.

Also make sure to use diodes to protect your Ledwiz from inductive loads like relays, contactors, solenoids and motors.
