I was hoping to find a "Fusing for Dummies" type of reference here, and greatly appreciate your link that seems to cover this, along with many other allied topics. Maybe this should be a prominent sticky here, if that is not already the case. I lucked out immediately on this keyword search, saving me from starting up a new but redundant thread. I'm posting in this one year old thread because it seems relevant and a logical place to do so.

Guess I'll have to read through this to find out if my assumption that all these fuses for pins had to be of the 'Fast Acting' type was correct. At the moment, I'm needing to replace a fuse or two on an EM. The voltage question seems to be addressed in the Marco link I'm putting in below.

Had to do an online order, since some of these sizes are hard to find. Went to Frys: lots of marked items on the wall of that aisle, but NO stock ! Ace Hardware has a selection of sorts, but not what I needed, and mostly the Slo-Blow type. Tried the local Radio Shack, only to discover it had gone out of business ! Not a huge surprise, since their business model always sucked: there is almost nothing they carry that you can't buy for 1/4 their price elsewhere; all they had going for them was their ubiquity and the "7/11" convenience factor. I expect they must be shuttering stores right and left by now.

I think this is the one I needed:

12A is not so easy to find, or at least it wasn't when I went looking for some in stock.

The coils ref in your link looks like it will be useful too. Thanks again.

OTTOgd,

That's certainly a better idea than the way I've been doing it. Guess the place to start would be with writing up an inventory for the pins one has. The operation manuals for some older pins like Gottlieb EMs could be rather skimpy, compared to many SS or later ones. I usually find a parts list, but there may be no mention of fuses at all. And I've bought game-specific kits that claimed to have the right fuses, but missed on some.
