hook it to a tester (voltage).you could do the redneck way:start the vehicle and then remove the terminals,if vehicle stalls alternator shot.if it doesnt turn on all power assessories (lights radio turn signals radio etc ) and see if it stalls. if not alternator good.if it does stall then alternator weak. we do this alot on demolition derby cars to test them.

the particularly contemporary (amps) from the alternator relies upon on the burden (the state of cost contained in the battery.) a sturdy bench tester can attempt this yet in simple terms checking the output voltage at 1200-1500 rpm's (13.8-14.2 Volts) will determine the subject of the charging device - if the voltage is right, the alternators score in amps is likewise ok.

Depending on what year the car is . If its computer controlled don't remove any cables while its running!A Quick way to check for charging at the alternator is to hold a small pocket screwdriver at the rear center of alternator if there is a magnetic pull then its charging.

I'm guessing you mean you're having trouble with your alternator? best way is to turn the car on let it run for a minute then unhook the battery while it's still running. let it run for a minute to see if the altenator is working, if it is, the car will remain running.
