Quoted from KSUWildcatFan:
Generally speaking you shouldn't have to replace coils simply due to age. More commonly you'll see them having gotten to hot at one point and the sleeve will be stuck. That or actual physical damage would be a reason to change it out. I definitely don't replace them by default when I do flipper rebuilds. Thats not to say you *can't* if you want to! Personally, I'd save any off to the side that don't have stuck sleeves. They might come in handy someday.
I'd make really certain the EOS is right. Maybe go through your symptoms a bit more and see exactly WHEN you're blowing that fuse (is it immediate on flipper press or if you hold it for a second? Etc) and you might look at buying a breaker so you don't kill a bunch of fuses while you research. Just an idea!
Yeah, I will definitely look at the EOS. ATM, this flippers coil is shot. The sleeve is stuck and I am getting 160 ohms resistance and you could smell something burning coming from it. The flipper was stuck in the up position. I will see about some breakers, I know I have seen others on here use them, sounds like a good idea for troubleshooting.
When the fuse was going it was just happening in normal play, I don't think I was doing anything unusual to the flipper, the button would just stop working.
I haven't really looked too much at the other flipper, but it has a different, newer coil. I bought two new ones and I figure I will swap them both out so they are the same coil and then I will save the working one as a spare.
