I have a few issues with the above.
1) generally im trying to get my alternator tested because i think its not working ie its output is nearly 0 amps. so even a puny 20 amps at idle is more than 0 and at least SOME indication that the alternator is working.
2) he talks about instantiously applying a (test) load to the alternator and some how this is unreaslitic? ummmmm oddly enough its JUST like when i flip the switch on my 4 140w daylighters! there is no, they dont come on kinda dim then finally get bright, BOOOM they are on and drawing 40 amps. THe regulator CIRUCUT (ie electrionics) is just that, electronics, capable of "responding" in fractions of a second. So why there may be a fraction of a sec that the lights draw off the battery, the alternator SHOULD be able to ramp up output with in a sec or less.
I have always considered autozone/advance whatever that test alternators as is it DOA? not "is it still capable of putting out full design rated current"
