I've recently picked up a RFM and ive had to do some running repairs to get her going. First was the monitor which has been corrected, a GI lamp issue which is now fixed & a few issues with getting fliippers and switches to react correctly. The final issue was a slightly weak right flipper. its about at 80%which is an issue as it lacks enough power to get up the centre jump shot.

IVe tried various times to reposition, clean and re-build the flipper to get it going at close to 100% and nothing worked, so i ordered a flipper rebuild kit, including a new EOS. I completed the kit re-build and it looks great, but when i went to test it -the right, rebuilt flipper was not responding at all.

I tested the right flipper button in diagnostics and it worked fine. no issue there.

I then checked the fuses and noticed that 104 was blown, which made sense as that protects the right flipper. i recently picked up some fuses for this machine as its the only one i have that uses these small ones. I asked the chap at the tech store specifically for the ones for this machine, a T4.0 & T5.0. I replaced the fuse with a T4.0 and turned it on. The fuse did not blow, but black smoke started to come up from the resistors in the centre, below the fuses. I turned the machine on and re-tested the 104 fuse and it appears to be fine. I notice that the old T.40 fuse does not look like the one i replaced it with. The old had a thin, straight flint inside where the one i installed has a spring style inside. The engravement on the new fuse says S4.0 / 250V. Is this possibly the wrong type of fuse?

I have not turned the machine on again, i have swapped over a good originaly, 4fuse from the neighbouring fuse holder, and put it into 104, and used the new 4 "spring" one in that holder. Have not re-turned it on yet as not sure what i need to check to make sure further damage is applied.

Anyone have any suggestions on what i should do next to test, and what the issue might be? I never unsoldred the coil so that has not been modified, the only thing i re-soldered was the EOS.
