90 s13 sr20 electrical issues!!!

[Project_Drift_Car]

So I picked up a 1990 S13 hatch not too long ago with the intentions of have a purpose built drift car. I've recently started having electrical issues. To start the car, I either have to jump it off or roll start it but even with jumper cables attached with the motor off or on, I have no power to anything! No power mirrors, brake lights, dash, windows, ect. My headlights come on but the motor isn't lifting them up. Yes I have checked all the fuses

You need to check your alternator & battery main wiring to make sure the wires are not loose. At battery, at alternator and at the main grounds on the intake manifold and battery tray.

There are also square 'fuseable links' in addition to the regular fuses - check in the fuseboxes under the hood. I think Autozone etc carry replacements, otherwise you might need to steal them from a junkyard Nissan.
