Replace the power board fuse


Q: The fuse on the power SLA / NiMH / LiBA /DC /PV board has gone defect.

A:  The fuse can be replaced.

Find your power board type in this manual, look for “power” or “battery” fuse.

When found, order (depending on the board type) a 4A, “0454004.MR”,  or a 2A, “0454002.MR” fast or slow acting fuse. Manufacturer is  “Littlefuse”, available at your local electronics store.

T: ML-PB-LI and ML-PB-3LI board’s don’t have fuses on the board. Fuses are integrated in the Lithium battery’s.

Before replacing the fuse, pull the power cord (the red and black cable) from the main board.
