Yes fuses new or old do tend to blow at anytime for any reason.Fuses are the weakest link in the chain

Stress, heat, vibration, and age can all play a part into why a fuse can blow. However, I would expect maybe one out of 25 old fuses to blow at random.

Also, if you're not sticking with some of the known quality brands, that could be a factor as well.

Most of the time, I'll put fresh fuses in a project game.

"Electrical Fatigue"

Corrosion can cause problems too. And on Data East games the fuse clips actually crack and break.

Are you running any surge protectors? I have very good ones on our games, and unplug them when not using

Theres always that made in China factor too

Three things:

#1) For any game, heat will cause fuses to blow (they are mostly thermal devices) so loose connections, corrosion, etc. on the fuse holder which could cause spot heating.

#2) For E/M games with linear power supplies, high line voltage will cause higher current draw

#3) For more recent games with switched-mode power supplies, low line voltage will cause higher current draw. Voltage distortion / waveform collapse related to too many nonlinear (not sinusoidal current) loads on the circuit might also be an issue.

Because you seem to be having problems across multiple games, check your line voltage. Could be undersized branch conductors, long run length, loose connections on outlets, etc.

Electrical power quality is (one of my) day jobs; I imagine folks with a lot of games plugged in might run into problems overloading a circuit now and then.

Just replaced a fuse on my DESW GI that was weak. Had a 3v voltage drop across the ends of the fuse.
