So its a 90 dx 5 spd i just got a new battery and alternator installed but my battery is gettibg drained somehow i checked my fuses as well as the wires from battery to alt and they seem to be fine no broken wires or corrosion.. all the ground wires are good too.I dont have an alarm or stereo to drain power and i disconnected the light inside. Im pretty lost and could use some suggestions!! ....also i took the car to oreillys and had them test my battery alternator and starter and they say nothing is wrong

 

Check the light in the trunk.
