Power issue

[Inflegend]

Hello all, first I'd like to thank those that helped me with my fuel pump issue on my 91 Q45 base,I had last year. It turns out that the control unit ground was bypassed and the fuel pump ground came loose! after spending a bout a grand on parts as a process of elimination it works great!
2 days ago , my dash functions went out as well as my mirrors, turn signal, blower, shift release, trunk release, fuel door release. I noticed my alternator isn't charging my battery also!
Is there a main ground that controls all of these functions at the same time? If so where is it located?
Fyi all my fuses all checked out fine!
anyone out there if you have any insight please let us all know.

Thanks a bunch,
Inflegend

Have you checked the large fuses in the fuse block under the hood as well? There's enough gone wrong here that it's definitely more than one fuse.

Yes i checked the fuses under the hood, but i'm hearing now from a few people to check my battery ground connection at the frame or chassis. It's raining today so as soon a it stops i'll try that!
