check your ground wire from the voltage regulator. some of these cars, earlier ones especially, had the volt reg grounded to itself, ie, ground wire to a screw that attached the volt reg into the f'glass . if so, re-run the ground wire to the engine or the frame and most, if not all, of your needle wiggling will go away. also, needle will go to positive side for a short time immediately after start up and then should go down to 'zero' or close to it. some wiggling of needle and dimness as described is not uncommon below 1000 , on mine at 850-900. yet at 1000 rpms + it is fine. bill.
