Working on a Jurassic Park pinball on location

After having this game on location for awhile, I thought I might report on what types of wear and tear and damage I’m running into, and what was wrong with the game. I think we’ve found a few “weak links” relating to parts that probably should last a little longer. Check it out:

Problems with coil stops in newer Stern games

Lately there’s been a bit of a hullabaloo (is that how it’s spelled?) regarding coil stops on newer Stern games. I had it happen to me as well, and I made a video to describe what’s happening. It appears whoever is manufacturing the coil stops for Stern has used inferior materials and they prematurely come apart. I’ve reported this to Stern and will let you all know what they are doing about it. I expect this supply issue to be resolved soon and if you encounter this problem, contact Stern support. They should be able to send out replacement coil stops.

coil stop literally fell apart. There’s a non-ferrous “washer” that separates the stop from the bracket that appears to be made of low quality alloy that disintegrates.

The next day I returned with the right parts. Here are two videos covering the repair.

damaged coil stop can also cause the plunger to mushroom and then damage coil sleeves and get stuck.

Installing a dollar bill acceptor (DBA) in a pinball machine

This is a short video demonstrating how to add a DBA (dollar bill acceptor) to a new Stern game (in this case, Jurassic Park). The older Stern games came with the cable necessary but now they’re not bundling them. I take a cable from Iron Maiden, along with a DBA I pulled from Wizard of Oz, and install it in Jurassic Park before I put the game on location.
