Metric Fuse Question
Our club Discus2b has 5mmX20mm fuses in the instrument panel labeled
F4/250V. Could someone tell me what the amp rating is of these fuses.

Metric Fuse Question
Correct - fastblow 4A.
If you have any capacitive load (often some technically competent club member puts a largish capacitor in to make sure power isn't interrupted when switching batteries) then slow blow is a better option. The main purpose of fuses is to protect the wiring, and slow blow will fulfil that requirement.
