Default Fuse blowing

Hey guys, Just joined and wanted to ask a question, I purchased a Monster Bash machine last year and its great. I was just given an original Bally Eightball machine with a problem. When I turn on the machine the F4 (5amp) fuse keeps blowing, I have a little electronic knowledge but don't know where to start. I have a manual for this but am not really good at reading schematics. Any help for this newbie would be appreciated.

f4 is the solenoid fuse. when it blows there is prob. a burnt coil somewhere. check all the coils for burnt marks and or smell. dont forget to check chime coils, knocker coil, and outhole coil. most of the time when coils go bad they short out the driver transistor that operates that coil. so both will need to be changed. if all coils seem to be fine, bridge rectifier BR3 on rectifier board may be shorted out blowing out the F4 fuse and needs to be changed.

if you looked it up in the IPDB you'll have noticed it has a manual in English for it

Default How to choose a fuse?

The type of fuse should be selected according to the application. Grid-type contact fuses (such as HDLRT0 RT36 series) are generally used for power grid distribution; spiral fuses are generally used for motor protection; cylinder hat-shaped fuses are generally used for lighting circuits; For silicon-controlled components, fast fuses for semiconductor protection should be selected.
