I have a 2004 320 with two 6.2 inboard V-drive engines. Smartcraft has worked flawlessly since I owned it. Was fine on Saturday and when I came to the boat on Sunday I had no gauges and the LCD Smartcraft readout said it lost Engine Data Bus.
There was a large storm overnight, however I see no evidence of other electronic issues or evidence of direct lightening strike.
Engine runs normally. There is power to the gauges, but no data - no data on my SmartCraft Mobile thing either.
Based on other threads (which are all old) -
UPDATE - I spoke to Mercruiser on the phone and they were very helpful and knowledgeable. Never would have thought that on a 20 year old system. They gave me a couple things to try to isolate each gaugue cluster before calling a tech with a diagnostic tool. It may be one gaugue that's putting too much resistance and making them all wacky. I still welcome any input/experience.

Based on other threads (which are all old) -
- I did a hard reset of gauges
- I removed and reseated all connections; checked for corrosion and bent pins
- I tried a different junction box that I know works (behind helm)
- I removed batteries for several minutes
- I can't find any related fuses to this system (although some searches say there is one, but it's not clear where)
- Someone said that electrical storms can damage the smartcraft function in the PCM/ECM - anyone know how I can test that and what pins they would be?
- I'm going to try to connect my Smartcraft mobile device directly to each engine to see if it gets any data; if so, I know it's either the harness or gauges.
