Description

The MS3Pro ECU’s feature user-replaceable fuses that protect against voltage spikes and other abuse. To replace these fuses, use a needle nose pliers to pull the fuse out of its holder, and then push in the replacement fuse by hand.

This is the 6000mA fuse used for protecting the main 12V power supply in the MS3Pro Ultimate and EVO ECU’s.

Fuses sold individually.
