    2019 Ranger 520c loss of voltage

    I have a 2019 520c that has intermittent voltage loss to PC board (under front deck)at front of boat. My question is where is this fused at? I’ve looked at schematic on rear deck lid and I don’t see dedicated fuse to that pc board. I have checked all fuses I can find in rear of boat and all ohm out good. Just wondering if anyone has had a issue like this and what was the fix? Tia.

    Your fuse block might be located in a different area,but I have a 2021 Z518 and mine is in the front deck starboard storage,and mounted to the partition between it and the cooler.

    That board is simply a Terminal board for 12v and ground, it is not a “printed circuit”-PC board. Look in your owners manual page 39 and you should find it goes to J3 pin #1. https://www.rangerboats.com/content/...ual_2019MY.pdf
    This terminal board / J3 can be overloaded with multiple graphs, FFS, accessories, etc. which is why many of us run 10AWG marine grade wire from the cranking battery to the bow. It is not fused and uses a breaker, which is also discussed in the owners manual electrical section.
    Cheers
