Hello everyone, I recently fixed a Hot Tip (SS). It had a burnt out
drop target reset coil, so I ordered a replacement. When I received
the coil it didn't have a diode for some reason, so I took the diode
off the old coil and put it on the new one (Yea, I know, not a good
Idea... but I was in a pinch to get this game working). Anyway, I
played a few games perfectly but after ten or so games I noticed that
the coil was getting weaker and eventually it didn't have enough
"juice" to pop up the targets. (I also noticed that the outhole had to
kick the ball a few times to get it out). A game later the solenoid
fuse blew. I think it is a bad diode...What kind of diode should I use
one the coil?
Thanks,

Max,
Rarely will diodes and transistsors slowly fade away. For testing
purposes, just remove the diode. Unless the coil perks right up, it's
probably a poor solder joint or connection that's causing your issue.
The diode basically shunts a counter current generated from the coil's
collapsing magnetic field. I wouldn't run without it for long, but a
couple of cycles should give you your answer.
