Electrical Guage Question

Hi All - I have a 2016 276 BR with 97 hours on it (my second season with the boat)  I noticed that when I adjust the trim tabs all of the guages move slightly.  I am wonder if it because of the high voltage draw of the trim tabs of something else. I never noticed it until recently though it may have been occuring since I have owned the boat.  The batteries are new and the alternator guage is reading between 13 and 14 volts when the motor is running.    Currently it is not a big deal, just curious if it is a symptom of something that I should be addressing.  Thanks

    The trim tabs are electric and not hydraulic. The cylinders are little electric motors and they draw a lot of current. My guess is that this has been happening all along and it's not a problem.

    I'll verify this weekend but I'm pretty sure my volt meter moves just a bit when I hit the trim tab button.

    Check all of your grounds and clean if needed.

    Thanks for the info...are the gounds in the back starboard corner by the battery isolator?

    I’m not sure where they would be on your boat. There’s definitely some on the backside of the engine. Also look for a black terminal block with a bunch of wires going to it.
