Left turn signal better than right

I still get twitchy ammeter....all connections were cleaned well....and clean to start with as this was low mile granny car. I use a relay from the battery where the regulator gets its + battery from. Car charges good. Just twitchy under light load. Light twitch...and no swings into the negative or anything. Wonder if my hei is causing it. Ammeter connections were clean and tight. No burnt or crusty connections. So far a year of driving like that and no problems so I just left it alone.
