Check all your ground wires and the power wire that goes to the alt.
Check all of your connections related to the charging system too. Also: You might have some resistance built-up in some part of the wiring. Any signs of green on the strands by the terminals is pretty tell-tale...
Go beyond the "bolt-on".

Hey! No thread jumping!
