I have a 1995 geo tracker installed a starter , it started fine but negative post on battery got hot now wont start at all just clicks

New battery....or alternator.....try boosting it if it starts leave it running and remove cables... if it quits when u remove jumper cables then u need alternator or check its fuseable link ........if it stays running it was your battery and your starter was probably ok i...u didnt need to change it or both starter and battery were bad ....starters kill batteries when they are failing and start to draw too much amperage from battery ...another quick way to tell a battery is dead,,,,,,is to look and see if its swollen or bulging...tis the season for batteries and alternaters ;-) good luck
