Battery and Ignition Circuits:
The OEM battery and Ignition circuits are fused in the block. Power for these circuits
enter the Smart Fuse Block IPX is fused and fed to the connectors, without any control.
If the rear fan, 12-volt outlet, vacuum, or sofa fail to operate, check the fuses, F1 20
amp, F5 10 amp, F8 20 amp and F9 15 amp, using a test light. If any of these have
failed, replace them with the same sized fuse. If these are all good, check the OEM
power feeds coming into J6 and J3. Failure of these outputs would rarely be traced to
problems in the SMART FUSE BLOCK IPX.
