SBSerpent, the back half of the Alternator requires Grounding. There should be a threaded hole for a GND Screw... ~5/16" dia size...
If you can get a 1inch long machine screw, Washer, GND cable , Star Washer you are all set. Note put the Star Washer between the GND Cable and Back case of the Alternator. Then the Washer and Screw Head complete the sandwich.
The Front of the Alternator with the Belt/Pulley assembly is insulated from the back since Alternator cases are made of 2pieces.

Then run your cable (if 0.25" dia cable, it may be actually 8gauge which is good up to 6ft of length) to the chassis GND or the GND on the Solenoid. Also use a Star Washer between your Cable, Solenoid post/cable you are attaching it to...

Keep us posted on the results....
Good luck...
