charging ac now car wont start!

[kylekinnamon1989]

1990 nissan 240sx with 91 ka24de... so my car was running and i was charging the ac.. everything was going fine and then while charging, my car just died!!! and now it wont start back up.. battery is fine, starter is fine.. none of the dash lights come on and i dont think the ecu is getting any power to it cuz i tried to check the codes but the light was not lighting up. i also checked all the fuses... any ideas?

check the fuses by battery

You probably locked up the A/C compressor. Cut the belt that goes to the compressor (unless it goes around something else too like the p.s. pump) and see if it cranks up. If you were putting the refrigerant in as a liquid and you put it in just a little bit too quick you could have very easily locked it up.

it does not crack up at all.. no click or anything.

It doesn't do anything when you turn the key? Does s*** inside the car still work like the lights and stuff?

maybe you overcharged your system and the high pressure sensor put out the signal to shut off your ac but it popped a main battery fuse because of age?

does nothing at all!! the door lights come on, the door chime comes on but no crank, no dash lights, i dont think the ecu is getting power either.. which one is the main fuse?? cuz i checked all of them and their fine

[kylekinnamon1989]

ok.. so i went to roll my windows up and that doesnt even work.. nor do the automatic seatbelts... YES THE BATTERY IS GOOD!! and the starter is good too!!

u blew a fuse. those are fusible links. they are just fuses. look at the 75amp alternator fuse.
