Voltage Gauge wiggle w/ turn signal normal?

[aa909]

Hey guys, quick question

I've got a 2014 BDR and just had the engine rebuilt and reinstalled. Running down the check list after 100 miles to make sure everything is working properly (so far so good).

But I noticed the volt gauge needle on the dash will wiggle back and forth about 0.3 volts when the turn signal is on (FYI the needle stays pinned at 13.5-14V at idle and 14.5V when driving without the turn signal on). I never paid close attention to the Volt gauge when driving so I can't recall if this is normal or if I have a ground issue somewhere after reinstalling the engine.

Thanks in advance for your feedback!
