Do not worry about excess RPM, it came out of a car with 3 or 4 times the RPM, and alternators like these are self limiting on output amps. The issue is where the amps are going when the ignition is turned on. I would not change anything until a different good amp gauge was installed. Knowing the real numbers is important in this case. The light bulb test you describe is normal, but does not allow a number to be associated with the amount of draw. A good quality Multimeter will have jacks located on the front to allow a 20 amp load to be placed across the leads. The meter is placed between the battery post and removed terminal (as you did the light bulb. Using that, a good amp meter, or a hold against the wire meter (cheap at the auto parts store), Will measure the actual draw (which should be about 3 to 4 amps with the points closed, and near nothing with them open.
