Good morning, my name is ***** ***** am I speaking with?

Are there any accessories such as lights, radio, gauges or a fishfinder that get their power from the key switch?

Hi Dakota,

The fuse is for the purple ignition wire on the back of the key switch. Disconnect all purple wires on the key switch, turn the key to run, and let me know if the fuse blows again or not.
