Help electrical problem I think 1990 N/A z32 2+2

I'm getting fed up with this car... I love it to death but man its costing me an arm and a leg. Ok the problem started on my way home last night. I was doing 70 on the highway and all of a sudden the dash lights for the E-Brake, ABS, came on now they never shut off while the car is running. Everything is running fine and it drives like normal just annoying to look down and see the warning lights on. Any help is greatly appreciated.

Another problem,
The A/C randomly cuts off an on no particular time as long as I'm not stopped. When it cuts off the headlights and backlighting for the gauges gets really bright. I think this is the fan clutch but wanted a second opinion before I spend the money on it. I do have a system in the car and when the A/C cuts off my subs also turn off. The car has an optima yellow top battery in it, Could it possibly be an alternator problem? As I have already had to replace an injector that was trashed lol probobly my own fault though.

Thanks in advance for any help you may be able to provide

sounds alternator related. i have a problem with my e-brake coming on also. car runs normal but the e-brake light stays on sometimes but i dont have the problem with the ABS light.

yeah it sounds like your alternator is going bad, in my z31 mine did the exact same thing about 3 months before it went out completely. its "overcharging"

and about your warning lights, i'd check fuses and links, if you havent already, those are usually the culprit.

I checked all the fuses before i posted but not the links i will look into the liks as soon as i get off work could it possibly be any of the relays??? As for the alternator i guess i will be calling dom ireggi to have a high output one made


Thanks for all the help
