Amp meter fluctuation?

Say, would anybody know if it is normal for the amp meter gauge to fluctuate rapidly during idle and even more so when the directionals are on?

When the rpms are raised this dosn't happen. Also the fluctuations are directly timed with the fluctuations of a rough idle problem I'm working on.

I don't know if the electrical is causing the rough idle or vice vesa. Any suggestions would help. :scratch:

Thanks!
