RE: [CA11] Smart Pilot melted 2A fuse, blown board
Rick,

The 2A fuse is responsible for powering the SeaTalk bus. The most common causes for such failures would be a lightning strike or wiring problem. If you are uncertain how to go about troubleshooting a short circuit, then it would be recommended that a Certified Raymarine Installer be contacted to visit the boat. The following voltages should typically be observed within a properly functioning SeaTalk bus within which communications are occurring (recommend using a common analog voltmeter / multimeter):
- SeaTalk power (red) to SeaTalk ground (shield): +12 VDC
- SeaTalk data (yellow) to SeaTalk ground (shield): pulsing +9 VDC to +12 VDC
