Hook
Data East, 1992Hello!
I just finished rebuilding my flippers on my DE Hook and installed new flipper coils, as well. However, I somehow blew the 1/2amp fuse that drives the DMD display and, of course, the only smaller fuse I have is a 1/4 amp. I have virtually every other size possible, except for 1/2 amp. Can I temporarily use a 1/4 amp fuse just to play a few games with the new snappy flipper rebuild? I'm dying to play a few games!
Thanks!

unplug the power cable to your dot matrix display and retry. Are you sure the fuse that's failing is for the display, double check this, ok.
I will have to try that tomorrow, but it is the display fuse, since the display worked fine for about 5-15 seconds and then goes out and it's the same fuse blowing. While I did install two new coils and reattach a wire to a ball trough switch that I knocked loose, I also installed a new coin door and removed the side rails for painting. Put it all back together tonight and now the fuse is blowing, when all was working before. I reattached all cabinet grounds, but the game operates just fine, except this new fuse issue.
When the display goes out do your controlled lamps go out as well?? Is the fuse your calling a display fuse located on a board, or remote mounted in it's own holder on the metal backboard?
No, only the display goes out. All other GI, feature lamps and back box lights continue to work. The fuse is the top of the five horizontal fuses on the power board, top left of backbox, above the ppb board.
The only thing I can think of is something got pinched or stretched when I lowered the backbox (very carefully onto padding) to screw the side rails back on.
well then next I would unplug the power cable at the display, replace the fuse, and power back up, see if fuse blows. if it still does the issue is in the circuit that supplies power to the display (on the power board)You also need to meter all the voltages going to your display (5) and make sure they are correct. Some are generated on the power board and one may have failed.
If you use a lower-rated fuse, expect it to blow. You're just wasting fuses by doing that.
Check hardware and auto stores for the 1/2 amp...it should be a fairly standard one.
It's possible that there's nothing wrong and that the original fuse blew because it was fatigued. If you put in a fuse of the proper rating and then that one blows, then it might be time to troubleshoot. Until then, it may be a bit premature to do much.
Well, good news! I bought some 1/2 amp fuses at Radio Shack and popped one in when I got home and it's been fine ever since! I've left it on for more than an hour and played several games and everything is good to go!
Thanks for the help!

Quoted from Freeworld:.25 of a amp on a fuse fating will make no difference.
its 100% out of tolerance....yeah it will matter
