ok, so, I know its been a long time, I apologize for that.
suffice to say, quite a bit has happened since my last post as I lost my mother 4 days after
I have, however, been able to resolve the issue (I hope !)
Im going to try and break it down, but this is an "how I understand it" post, so I may make a mistake.
here is the series of events as I understand it, my amp + line got rubbed through a little and was grounding out against the frame, not enough to kill power, but it was enough to cause surges and ebbs to the point of damaging the Alternator, which in turn put more pressure on the battery. then it became a cascade effect, the battery would require more charging from a failing alt. eventually, the alt went completely bad, so I replaced it. but the damage to the battery was already done, so now with a new alt trying to charge a battery that literally cant be charged to capacity, putting a lot more strain on the alt (which Ive read are pretty weak to begin with) the only good thing is I got a new, not remanned, Bosche
so all that seems straight forward, now comes the tricky part, somewhere along the lines of the dual failures, several fuses got popped all at once, both in cabin and engine bay... but... somehow, everything other than headlamps still worked... ? my mechanic still cant figure that one out, according to him, the windows/locks shouldnt have worked as well as blower/ac and alarm. but, they did. only thing that was actually affected was headlamps and it seems (unknown to me) tail lamps also didnt work, but since I couldnt drive at night for fear of my lights going out, it was sort of a moot point since brake lights did work.
so, all this to find out my battery (just over 1 yr old when things started happening) had a bad cell and several fuses (and 1 relay, forgot bout that) got taken out in the crossfire between my alt and my batt.
as of writing this, the car starts and runs excellent and everything, including headlamps, work
