Nissan Repair: ???, one witch, charging system

Question
My 1987 300zx non turbo is getting 12v to the fuel injectors all the time, and is killing my batt. I took out the ecm and still getting 12volts. I took out each relay one by one and found that the relay up by my batt (orange) was the only one witch would cut the power to the injectors. Help! What do i need to do next??

Answer
They are supposed to get power at all times with engine off! That is on the one wire. The other wire is what the computer uses to ground the injector so it fires. That will not drain the battery! Most likely there is a voltage draw from somewhere else. If you are not sure about testing for a voltage draw, let me know and I will give you instructions. Also, please check the charging system.
