im getting sick of unpluggin my battery. I bought my 240 about 3 years ago ( rb20) and i have had a problem with it dying over night since I first got it. It Hasnt been really buggin me til now. I bought a new battery 4 months ago cuz the old one is bad and had my alternator tested to and it was good. i did a multi meter test and i was getting a reading of .40 amps with the car off. so i took my test light and hooked it up to the neg. post and neg wire and the light turned on. its dim i cant get the light to go off no matter what i do. i have unplugged my ecu, pulled every fuse under the dash and in the engine bay. i also unplugged the alternator, starter, ignition switch, fuel pump, injector harness and coil pack harness. even with al this stuff unplugged the light is still on but my multi meter only reading .25 amps...

what am i missing cuz this is starting to give me a head ache?

also i touched my injector wires where they connect to the ecu with my test light and all of them are getting power with the car off andd the key out. are they supposed to get constant power?
