Test fuses out of the holder and never over-fuse
Check every fuse with the meter on continuity after pulling it, rather than by eye; this also reveals cracked fuses and bad holders. Fit exactly the rating and type specified (for example a 2 A slow-blow); a bigger fuse makes the driver transistor or coil the part that fails instead.
