Dead Gauges, Seat belts, Battery Light and its not the charging system '91 RHS13

[sicride]

Car will hardly run, rough as could be. Battery light is on but very dim, the gauges do not move at any time. The seat belts no longer move automatically. The car takes about 20% throttle to reach 2k rpms. I checked the grounds on the battery, changed the alternator (cause advanced told me the diodes on the alternator were shot- jackasses) I checked as many fuses as I could, saw no issues.

I really don't know what to think now. Is there a specific fuse anybody knows of that runs the gauges and the seat belts? I could double check that entire circuit? but I am kinda at a loss as to where to start on that one.

Fuse B (head-up display ctrl unit, automatic seat belt control unit, and instrument cluster)runs those. Its the second one up from the bottom on the left hand side, also fuse R (instrument cluster clock, Head-up display ctrl unit,and automatic seat belt control unit)the third one down from the top on the right side of the fuse box. Both of those fuses have something to do with the mentioned problems... Sucks, I am dealing with electrical problems myself. good-luck

Thank you. I checked the fuses again, the second one up on the left was apparently shot, I dont know how I missed it the first time. This cured the gauge issue.. I double checked all fuses in that fuse box and all seem look brand new (of course they dont ever look used, just blown). The seat belts still do not work. The power supply is still horrible. The battery light is now not showing. It seems now as though my brake light does not come on still when the e-brake is pulled. It also seems (key word there) that the throttle reading on my AFC is quite off. When I would believe I was giving it around 10-15% throttle it says 30+%. There is a chance that with it running like poop for the little bit I fowled the heck out of the plugs. I'll check them again tomorrow and see what kind of condition they are in, but this would not solve the ebrake light problem nor would it solve the seat belt issue obviously. So, I'm really guessing thats not the right next move.

Any other suggestions on getting the seat belts working? I'm not familiar with the wiring for such devices.
