Fuse
The MSD is equipped with a glass tube-
type fuse (5×20 mm/ 0.2”x0.79”), which prevents overcurrent from
flowing into the MSD when a circuit or circuit part is broken.
If the MSD cannot be turned on, first check if the fuse placed in the AC inlet is blown or not. If it is blown,
replace the blown fuse with the spare one by following the procedure below.
1. Turn off the MSD and unplug the power supply plug.
2. Remove the power connector from the AC inlet.
3. Remove the fuse holder by pulling out the depressed portion of the connection area for power supply
connector using a screw driver or the like.

Note:
In case the fuse blows again even after the blown fuse is replaced, the MSD may have problems. Please
Contact your dealer.
