Begin by removing the x2 M8 bolts to open your Redarc panel. Your two fuses are located in the 'OEX' fuse holders. Open the fuse holder like so to check your fuses.

To replace your fuses, begin by disconnecting the battery.

Use an 8mm socket to remove the x2 nuts on each fuse. Replace with a new fuse, the same amperage as the one you removed. Fasten the nuts and close the fuse holder. Close your Redarc panel and fasten the x2 M8 bolts back in.
