The MS3Pro ECU lineup is equipped with user-replaceable onboard fuses that help protect against voltage spikes, reverse polarity, and other electrical issues. This 375mA (.375A) fuse is used to safeguard both 5V Vref power supply circuits on MS3Pro Ultimate ECUs.

If a fuse blows due to an overvoltage or wiring error, replacing it is simple. Use a pair of needle-nose pliers to carefully pull the blown fuse from its holder. Then, press the new fuse into place by hand. Always ensure power is disconnected before attempting fuse replacement.
