Hi all, glad to have found this forum. New guy here from South Florida.
I believe I have a bad ground somewhere and would like to check all of them.

My electrical issues are AC, windows,, all dash lights do funky stuff. Gages drop,, sometime some and sometimes all. Sometimes the windows will work if I use a turn signal or flash the high beams but only for 10 seconds.

New battery, alternator installed

thank you in advance
