Hello again. 2023 ZForce 950 HO EX. What would cause the 'signal B' fuse (15A) to blow? She'll start and idle but once she's in gear (any gear), she'll blow the fuse very soon after you apply power. What's the 'signal B' fuse protect? Thanks.

Let's start by telling us what machine this is so we can move this post from the Info Center to the proper section. One would think either the service manual or the owner's manual would have the information on what the fuse supplies power to.
