Troubleshooting
Fuse blows
Test Open Output
Disconnect output wires from PCB for the bell that blows fuse. If fuse still blows without anything connected, the rectifier is probably at fault. Most panels have socketed rectifiers that can be replaced. Be sure to align the angled corner (positive lead) correctly when inserting the replacement.
Test Alternate Output
If the output in question does not blow the fuse when its output is not connected, try connecting the bell to another output (lower numbered output for high current fuse). If the other output fuse blows there is a problem with the striker or wiring.
