woke up to start my car to go to work today and noticed my whole cluster wasn't working like temp, tachometer etc (things not working listed below) i also notice my dome light, seatbelt alarm, and radio are not working. i pulled out my cluster just to see if i forgot to connect something but everything is what it should be

Car is an '89 240sx with SOHC KA stock, car starts up no problems

list of components that don't work

Cluster instruments:
Speedo, Tachometer, Temp gauge (all 3 do not move when the car is turned on, they stay in the position they're set to when the car is off)
dummy lights for brake, battery, etc, digital clock (lights up but doesn't display numbers) and the backlighting
(also i didn't list the fuel gauge cause that's been out since i even bought the car, never got to replacing my sending unit)

Headlight retract/pop-up
Light dimmer (for cluster)
Hazard button
Windshield Wipers

lighting - interior dome light, brake light, turn signal lights

Miscellaneous:
Radio
the Ding sound for when the Key is in the ignition and the door is open (ding, idk what to call it, maybe alarm too i guess)

searched some possible solutions
Tach - adjust CAS, check wiring to ECU
Speedo - speed sensor, bad ground or fuse
as for the rest most common answer is check ground, fuse, and wiring

i'm hoping i didn't fry something

super stumped at why they would all fail at the same time though never saw that coming, i searched on google and found this guys post on the 240 forum but no effin solution lol same exact symptoms as mine except my battery is brand new and the connection to the alternator is fine.

to moderator/admin: figured out problem.

bad ground from alternator caused the FL 75a fuse to blow, went to PepBoys, Autozone they don't carry the fuse. best shot is the dealership, junkyard, or shopping for it on the internet. or you can ghetto rig it and connect the terminals with a copper wire but i figure i can last a day or two without my cluster to get the proper fuse from pick a part lol
