A few people in a couple different threads and PMs over the past few months have asked me how I added a separate power supply for mods that is switched on with the machine power. There was 3 different ways that I did it … one method on a Stern SAM, another on a JJP, and another on a Stern Spike 2. This initial post could be a novel about it and what I would do different next time. Instead of that, I did a short video stumbling over some words to describe it, but the video would explain it better for people to understand (I think). See the video link first.
Now to answer where did I get those gadgets and gizmos, here are some links:
For the power supply, I got one that gives both 12 volt and 5 volt outputs intended for the standard molex connections that most mods are made with. I have yet to see a 5 volt powered mod, but if the standard pinball molex connector has that, maybe it exists. Bottom line is it could be over-kill to also have the 5 volts supplied. I bought that on eBay for about $17 at that time (a few people sell them) and this is one of the current links for those: ebay.com link » New Arcade Power Supply 16a 5v 12v And 5v Great For Jamma Multicade Free Ship
For the "Normally Open" switched relay for the 110 volt power to the power supply, I found this and it works great: http://www.powerswitchtail.com/
That is probably very similar to what Mike D used for switching the power on for the ACDC LCD Mod and his CFTBL Mod.
For the normal molex 8 way splitter, I use the one from Pinball Life at this link: https://www.pinballlife.com/index.php?p=product&id=4234
For the power splitter in the video that I'm going to use for the Spike 2 system so that I don't need a power supply and the power wont load down any boards in the pinball machine, I went with this one and like the idea of how it works a lot: https://www.pinballlife.com/index.php?p=product&id=4392
Pinball Life has a few other options that you can go with for it, but I liked this one the best. Read the descriptions about them on the Pinball Life website.
I'm sure some people might not like how I did one or more of these, so I and others would be interested in how you did it in a different way that would not load up the game circuits/boards/etc. I don't like the idea of just attaching mods to other things under the playfield, but sometimes the mod people give you little choice. Then there are some mods that do tap into the service outlet or bill acceptor power that have relays built into the mods - I like that even better. Anyway … how do you do it? Please share. Maybe I will change to the way you do it.
