If your exciter wire is bad, reving above 2000 rpms should self excite the alternator. If you let the car warm up and lights are still dim, but when you blip the gas once they brighten up and stay bright.. it's your exciter wire. Trouble with self exciting is the alternator can loose it later if you stay below 1500 rpms a lot.
Stock alternators are too small for the shark if you even add an aftermarket stereo.. Lots of folks switch to the Delco, or have the Paris-Rhome or Boschs rebuilt with more amperage. I had mine rebuilt with 160a core for about $250. I can run everything now and lights are always bright.
