The sticker that Nippon Denso puts on the alternators from the factory rates them at 70amps. A factory 70a rated ND will put out around 90amps. The aftermarkey manual is wrong, 30 amps will run the ignition and a cooling fan, but touching the brakes will cause more draw than 30 amps if the cooling fan is running. The headlight/parking light systyem should draw 20amps alone.
Thanks Tercel GTS, that is twice the Haynes manual screwed me lately! Unfortunately there is nothing better. The Haynes manual told me to open the engine drain plug to drain the water after a coolant flush, the damn thing seized up and wouldn't close, but luckily it isn't leaking. Later a mechanic told me never to open the engine drain plug on an old car as it will seize, yeah no kidding!
I am going to a different auto parts store to get a retest of the alternator and then if bad I will buy a new one. That is the only I haven't replaced yet, of the parts that normally go out on any car.
