Question about Coin Door Lighting
Question from Brandon: Hi Tim, got a quick newbie question for you. Just recently bought my first cab at a local flea market (Street Fighter 2 Hyper Fighting in a Dynamo cab) and ended up getting it for just $40 thanks to him thinking that it didn’t work. I knew absolutely nothing about arcade machines, but I’ve always been a huge gamer so I jumped on it. Unfortunately the cab itself was missing the SF2 pcb, but I recently installed a Multi-Williams and I couldn’t be happier. Thanks to your videos I’m slowly learning one step at a time and as of right now she’s running beautifully.
So first and foremost, I really appreciate it that you’ve took your time to put out this great video series. You’ve helped me immensely on everything so far, and I hope to learn much more from them on down the line. So again, thank you. For a guy like me who’s never crimped a wire in his life, your videos are an excellent source for people wanting to get into the hobby.
Right now I’m just knocking out a few of the minor cosmetic issues. One thing that’s been bugging me is the fact that the coin return buttons aren’t lighted. Haha, there’s just something about that warm inviting glow that would really complete the package. I watched your tutorial on changing out the bulbs but I’m still not entirely sure which type of bulb I need. I took a reading with my multimeter and I ended up getting around 15v on the reading. I didn’t notice anything above 14v on your chart. What type of bulb should I be looking for? Do I still go with the 756 bayonet bulb?
Thanks!
Brandon

Response from Jonathan: Brandon,
First off, thank you for your kind words. We’re glad that our web site has helped you with your repairs. Please continue to check back for more content in the future. As for your question, I would probably go with the 756 bayonet bulb even though your voltage is a little high. Have you checked your +5 VDC line on your power supply? If you haven’t, you might want to do that. It could be that the voltage coming out of your power supply is a bit too high and needs to be adjusted down. This might get your lamp voltage closer to that 12-14 VDC range that you need. With that said, the 756 bayonet should be fine at 15 VDC. It’s close enough that it should not have any problems.
Hope that helps. Thank you for your question and good luck with your repair.
