Good Day, I have a 2002 38 open and my starboard gages (oil pressure, engine temp, transmission temp, etc.) all are erratic.  Sometimes 2 of them will work fine but normally they are erratic.  I feel it is a grounding problem.  Problem is I have not been able to find the ground wire/cable off the engine.  Does anyone have experience with this and do you know when to find the ground cable?  Thanks

I have a similar issue on 2001 3800 Open with Cummins 450’s that just started with my port engine alarm alerting at higher speeds or in choppy water. Gauges are now fluctuating.  Have you had any success finding the cause? I have local shop looking at this week. They just installed new Garmin electronics and the issue has gotten worse.  Will advise what they find.
