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.

Alternator not charging 1989 Jeep Cherokee Laredo?
best way to tell if the alternator is charging is to unhook the battery with the engine running, if it shuts off then you know you have a bad alternator, i wouldn't recommend this with newer vehicles due to the fact you could hurt the computer but an 89 i wouldn't worry about that so much, good luck!
