alright so i need a little help pretty sure its the alternator but not sure yet want your guys opinion... ok so i recently added a detachable steering wheel to my 93 si hatch and since then the battery died or something cuz i was drving and i put my turn signal on and the rpms dropped to 0 when they should have been at 3k rpms then the mph stoped too and my stereo turned off so i figured i had a shortage somewhere or not enough ground but then battery appeared dead car wouldnt strat.so took the battery off and took it in to auto zone to get recharged and checked out and it was good took the starter in as well it was good to so i get back home put everything together start the car and start driving again the cluster starts droppin rpm's stereo turns off and eventually the car looses power then wont turn on cranks and everything but then stops completly appears battery is dead again this was all after a day of drving after i had the battery recharged so im guessing its my alternator not working? any one that could help that would be great i am running a supercharger so its kinda a bitch to get to my alternator haha but if its got to be done it will but looking for any otthere suggestions also checked all my ground including alternator and starter both were screwed tight.

Check whether the battery ground wire is tight and clean (good metal-to-metal contact). Also clean the battery posts and connectors and then tighten.

Jump start the car, remove the jumper cables, and then measure the voltage across the battery posts with a voltmeter when the engine is idling versus off. What are the readings?

Its called a parasitic drew you test this by removing the negative battery cable and connecting a ammeter in serious with the battery. Once connected you disconnect fusses until you find the one that drops the most amps. find fault in that circuit and fix.
