simple useful alternator test - with the car running at idle and no accessories, lights, etc. on. Disconnect your positive battery cable. the car should stay running if your alternator is functioning correctly. If it is, leave your battery disconnected from the alternator for the night, or for however long it has been taking to drain the battery. Reconnect in the morning and try to start it. Often alternators fail because a strain is being imposed on them by a battery short. It's good to replace both at the same time.

Miles per gallon of a 1990 Toyota Celica gt?

Up to 34. I'm getting 19 and when I did the test, I drove 175 miles highway and city. The highway was all between the speeds of 90-120 (mostly about 95) and the city was a lot of downshifting and angry driving, so you could safely say it's getting about 25 if driven like a normal person.

Please don't EVER EVER do this! Without a load on the alternator, if it is indeed in operation it will "full field"...essentially run wide open...destroying itself and most of your on-board electronics with it.
