ammeter is bouncing

mmm what was it?
I'm facing same prob with new alt, new mech regulator, new belt. Mine is only bouncing at idle...

I also bypassed my bulkhead connectors in the charging system so its not that mess. I'll buy a quality electric reg and see what it does.

I kinda also suspect the connections at the ammeter, but am being lazy about not wanting to pull out my instrument cluster.
