Hello all,

I just installed a new Pinsound Plus in my #LAH. I wasn't aware that there was an additional power boost connector that I could have bought so it was installed without it. I installed the pinsound without any issue, started up the game, and all seemed to work fine. About 1 minute into gameplay the left flipper stopped working. I turned off the machine and started researching. This was 3 weeks ago.

My experience with troubleshooting and fixing pinball machines is limited. I was using a cheap Harbor Freight DMM and in all my research through this forum I upgraded to a Fluke 115 and I have a very basic understanding of how to use it. I.e. put it to the sound for continuity, on the horseshoe for ohms, V for volts, etc.

I've done a ton of reading through these forums looking for step by step instructions on how to test different things but I haven't been able to find what I'm looking for. I'll run across something that will say "test the coil" but I haven't been able to find step-by-step instructions on how to exactly test the coil and what I'm supposed to see when I test it, which is frustrating because I'm sure that it's somewhere on this site.

Here's what I've done and found so far. I started a game and felt the flipper, and when I press the flipper button I can feel energy going to the flipper, but it doesn't move. I did a continuity check on every fuse in the machine and all tested good. On the PPB Board, connector J7, I tested pins 1 & 5 that feed +50v to the flipper board, and it was reading +76v. Since then I ordered the pinsound power booster and installed it with fingers crossed. As I figured, nothing changed. I tried checking the coils and flipper board for the +50v but from what I understand, as soon as you open the door, the +50v is turned off. So here I am asking for help.

Thanks for your time and help with this!

Thanks for your reply LTG. I didn't want to write up to much at one time but I have pulled and checked the fuse's with a meter for continuity. I did check for broken wires and found none. I did resolder the wires to the coil because it looked pretty hacked.

I'll tape the switch shut and check the coils.

Thanks!

I was able to test the coil today and it's reading the same as the right. The flipper can move freely with my hand so it's not stuck. So now that I know I'm getting power to the coil, what's the next step?

Here is a video of what’s going on.

Thanks for all of your help!

PinballManiac40 When I hold the flipper halfway up and hit the button the flipper fires. What does that mean?

Turns out it was the EOS switch that needed adjusting. I compared the left and the right and they looked identical so I figured it couldn't be the switch. I went ahead and put a little bend in it and it started working. However, the EOS was the last thing that I looked at.

As I was checking the CN2-8 and CN2-9 pins on the Flipper Board connector, I was getting 76V in stead of 50V. Is this an issue?

When you said prepare to jump I figured it was going to shock me and you were trying to be funny. So I didn't use my finger, I used a pencil, but it still didn't fire. I also cleaned the contacts so maybe that had something to do with it too.

Thanks for all of your help!

That makes sense now but when I read it I thought differently.

No, it was set to DC.

Is there a post, video, anything that would show me exactly how to do that?

PinballManiac40 Thanks for all of your help! Thanks to you the game is back up and running and my 2 little girls are happy again. They are 7 and 8 and are pinball fanatics.

PinballManiac40 Thanks for the tutorial on how to ohm an EOS switch! As for the Belles and Chimes, that's the first I've head of it. I quickly googled it and learned that there isn't anywhere near St. Louis MO that has that.

I hope you have a great Christmas and thanks again for all of your help!

PinballManiac40 Thanks! I feel like I just got my LAH dialed in, with everything working, and it went down.

I see that you have a Hook in your collection, how do you like it?

I see a couple for sale and I'm thinking about pulling the trigger because I think my girls would like it. I've never played it though.
