I am having a strange electrical problem (again).

When underway, I sometimes loose my GPS fix which makes my chartplotter go nuts and my GPS display goes nuts too (they are seperate in the 2001). At the same time my ST-60 just shuts down (this is the depth finder, speed, and temp thing).

I have not been able to duplicate exactly how it turns off and back on. I thought it was due to high or low voltage coming from my starboard alternator, but like I said, I can't get it to consistantly reproduce. It happens every time and I don't want to leave sight of land until I get this fixed.

I hope this is not a "replace your electronics" thing.

Any suggestions?
 
I'm feeling kinda dumb. I looked under the dash at the instruments (by just opening the chart door), and found a couple of loose connectons to the instruments. I pushed them all in tight and viola! everything works perfectly. Check your connections!
