The boat manufacturer may replace the fuse and holder with a circuit breaker. Have your boat manufacturer or dealer show you
the location and identify the fuse or circuit breaker for your reference.

a - Regulator
b - Wiring to DC voltage regulator
c - 30 ampere fuse and holder

e - To 24‑volt battery system negative (–)
If the vessel is equipped SmartCraft 3.0 Control and uses a 12‑volt system there are jumper plugs connected to the VIP to supply
12‑volt power to the VIP. On vessels with a 24‑volt system, DC‑to‑DC voltage regulators (three, or four in the set, depending upon
the application) take the place of the jumper plugs to supply 12‑volt power to the VIP and the other 12‑volt circuits.
The power package manufacturer protects the wiring, the jumper plugs, and the voltage regulators in the circuit against overloads
through the main circuit breaker in the VIP.
Have your boat manufacturer or dealer show you the location and identify the main circuit breaker for your reference.
