Insanely new to working on cars, very little knowledge, my ride is a 2000 eddie bauer edition ford expedition 5.4liter engine.
I triggered the problem to my alternator since my car ran just the battery never charged, I got it to ride buy using a battery charger and going where I needed to go, well what happened was my dad messed around with my voltage regulator because he thought that might be the problem, now the car wont turn over at all even with the charged battery, it wont even click or do anything, all the gauges and lights work fine it seems, also, the voltage regular is hooked up properly but its not grounded (screwed) into the metal of the car its kind of hanging there at the moment, could that be causing problems? I was thinking maybe it needs to be grounded but im not sure, like I said extremely ignorant when it comes to cars. If it would start with the charged battery I would just go buy an alternator, but im thinking something else is wrong now? thank you
