Is it a good advice for Gottlieb System 1 -machines to add extra fuses for the non controlled solenoids, especially pop-bumper-coils?

I have read it somewhere, but cannot find the source any more.

Thanks guys, the value 2A I have estimated roughly, should measure the way ForcelFlow described.

But the main question still is, does it make sense, to upgrade all of my system 1 machines with these fuses for saftey reasons? Problem is, that these coils are not CPU-controlled and if the contacts are pitted and this causes the contacts to "weld" together for a long enough time, the coil will blow and burn.

So what do you think, does that make sense, at least for the pop-bumpers?

I will also do this now on all my system 1 machines and try with a 2 Ampere SB fuse.
