SeaTalk Bus 12vdc Fuse ?

I have a Robertson autopilot and Raymarine GPS sensor, E-80 and old ST 50 instruments running on a Sea Talk bus. Today I changed out the non-functioning Sea Talk to NMEA 183 interface board with a spare that I had on board. I duplicated the wiring set up exactly but when I started the system up I had lost all Sea Talk information. The instruments are not up. No GPS signal to the E-80. The Sea Talk bus is not getting 12v power. Is there a fuse in that system separate from the breaker? Ay ideas where it might be? Any ideas what has occurred?

There could be a fuse, then again there may not, it depends on the person who wired the system. A seatch of the SeaTalk cabling should not take too long. The only other fuse in a SeaTalk system I am aware of would be in the autopilot, but as you have a Robertson unit we can exclude that.

You will have to take a methodical approach to trouble-shooting to determin where the power originally was sourced. Of course, you could also introduce an alternate 12V supply to the SeaTalk system.

its quite common that (a) thers a hidden in line fuse or one of teh connectors hiddenn somewhere has patially disconnected.

bad idea to remove fuses from instruments.if there is a spike or problem for the fuse to blow its better to find the problem than replace all your equipment. I had a customer who did that who now has to replace his ssb and power supply
