I take it you ran a wire from the Battery Pos. post to the Reg. "F" terminal.
That will take all regulation out of the system and burn up bulbs and the fuse links from the alternator to the starter sol., maybe the fuse links opened and saved the battery and alternator. Make sure the regulator is grounded and not saying you have ground problem but you can never have it grounded too much, in this case the more grounds the merrier.
You may have all of the bulbs burned out or a bad fuse for these systems.

Do you have a testlight or voltmeter, and know how to use it? You will need something like this to figure out the tailights.
One ground from the battery to the engine is not enough. The engine and tranny are mounted in rubber motor mounts. You need small grounds from the engine block to the sheetmetal up front and also the firewall.
