You do not want to mix them up! The labeling on the board or schematic will specify slow blow where they are used, otherwise you can assume fast blow/regular fuses are used.Īlso, black lead plugs into the center plug labeled COM, red leaf plugs into the port too the right of that one.ħ3BC7775-48FB-47D9-B4E6-71CBB7E4D566.jpegįrunch Ok so i started with F3 fuse, since I previously viewed a M&MPM repair video where the person stated that this specific fuse kept blowing and the game wouldn't start. If it works, proceed to test the fuses by placing a probe on both ends of the fuse and listen for the beep.Īlso, it's important to note that fuses come in 2 main varieties on pinball machines: slow blow (also known as MDL) and regular/fast blow (also known as AGC). Put it on this setting and touch the probes together and see if it beeps. I'm pretty sure you'll get a beep from it when detects continuity. Here's the setting you want to put it on. Make sure the amps match up with the ratings listed on the board you're pulling them from. They will usually say something like 3A 250V and some other abbreviations as well. You want to set it to that function, hold each of the meters probes on either end of the fuse you're checking (again, pull the fuse out of the holder to check it) and the meter should beep if the fuse is good.Īlso look closely at the caps of the fuse and see if you can determine the amperage and type of each one. Most meters will make a beep with the continuity function, so when you touch the ends of the probes together you'll get a beep out of the meter. If you want to send a pic of your meter i can point out exactly which setting we want. Pull each one out and set your meter to check continuity. I believe yours is located on the bottom of the cabinet?Įither way, the fuse values are likely listed on the board. I think we're talking about the same board. Im assuming you mean to pull the ones on the Rectifier Board correct? I have all original boards installed minus the s&t board that is a repro. What exactly should i do with the meter to test the fuses? Im assuming you mean to pull the ones on the Rectifier Board correct? The LEDs on the MPU board are not lighting up anymore. As long as you're ready to learn a few things and carefully follow the sage advice of techs like wayout440, you'll get there!įrunch thanks again for the help. You'll get you're game back up and running! Just gonna take some time, money, and patience. It sucks to have something like this happen, but we've all been there one time or another. What is the LED on the MPU doing when you turn on the game? What kind of boards do you have in the game currently? I think you may have already tried it, but do so if you haven't. This is also a good opportunity to verify that you have the correct fuses installed in the game if you haven't already.Īs also suggested, try unplugging the sound board and see if the game boots. There's several fuses on the board sitting on the bottom of the cabinet (the "Power Module Board"). I'd begin with his suggestion to start pulling fuses and checking them for continuity with your meter. wayout440 is an excellent tech, def follow his advice moving forward. You'll be able to get the game going again, but it may indeed require a few new boards.
