lights going crazy, could use some help

I think I narowed it down The lights and gages go crazy when I step on the gas but only when there is a load on the motor could it be the alernater(it charges the battery just fine)

loose or corroded ground(s) and/or wire(s). even if battery and grounding connections look ok, still clean really good

When random crazy shit starts happening: Check all possible grounds.

Check your grounds then you might need to get a new voltage regulator, same thing happend to me but i never had good enough grounds for the load so it kept burning out the regulator and the problem would happen over and over again.

I took the groud from battery to frame sanded down the contac and the frame No more crazy lights and tack. thanks guys
