Fused B+ Power Supply




MoDiC Fused B+ Power Supply







The MoDiC receives operating power from the vehicle battery through the connector plug.
The connector plug has a 2.5 amp power protection fuse located in the cap that protects the MoDiC power circuit.
If the MoDiC does not power up when connected to the vehicle, check the fuse condition.
As with any fuse replacement, determine what caused the fuse to fail and replace as necessary.
