Hi... When I use either left or right turn signal the battery gauge moves in synchronization. Can this be a bad ground?... and if so where should I look first to fix the issue?

Thanks!

Doubt if there is a problem. Sometimes the gauge has th esame power source as the t-signals, and will show the fluctuation on the gauge, wouldnt worry about it

Thanks for the reply... I thought of that also, but it seems them particular gauges and turn-signals have their own fuses. So I thought a bad ground may have been creating it some how or the volt gauge is going out.

Own fuses but power origin is the same
