I have a 2005 420 Sundancer with 480 CE Cummins engines. The system monitor was unplugged when it was purchased. I plugged it in and it flashes all systems ok. When I turn the ignition switches on there is an alarm and it reads data link failure. Checked some grounds and even ran a new one with no change.
I went to my local Marine Max and was told they don't work on anything older than 2006! Any opinions on the next step or has someone had this problem?
