I replaced the alternator and battery a month ago. Jeep was starting fine but today I went to start it and it wouldn't start. I can hear the starter solenoid clicking when I turn the key. I got a jumpstart and it started with no hesitation. When I got home I changed the oil and went to start it after being off for only 20 min and solenoid clicks but no start. I figure it's either a bad ground or the starter. I'm starting by cleaning the grounds and hopefully that solves the problem. I just need a list of all the grounds. Any and all help will be greatly appreciated.
