My car sometimes shuts off when I attempt to start the car. I start the car, hear a loud click and the electricity to the entire car dies. No dome lights, no headlights, no radio.
I disconnect the negative terminal and re-connect and all power comes back.
The weird part is, sometimes it DOES start. Sometimes it starts on the first try, sometimes I have to disconnect/re-connect 9 or 10 times before it’ll eventually start. Once it starts it never loses power or has any issues.
What could it possibly be?!
I’ve ruled out the battery, as it’s literally brand new. The connections to the battery terminals seem VERY secure (I’ve re-done them a few times) and there’s no corrosion at all. I sandpapered to be sure. I’ve also ruled out the fuel pump (obviously).
Could an aftermarket alarm system inherited from a previous owner be doing this? Could there be an issue with the starter? A connection issue elsewhere? Is there any way I can track down the issue on my own? Any help would be appreciated. I’ve been trying to save money by working on my own car - if it’s too advanced a job I don’t mind taking it to a garage, but I’d like to at least figure out the issue so I don’t get ripped off!
Thanks in advance!
