I have a 2005 Street Rod. For a while now I have been having Battery drain problems. Getting worse recently to the point of the battery draining to 6 volts in 12 hours. There is a current drain of around half an amp. I have been isolating various circuits. Only when I pull the 15 amp ECM fuse does the problem go away (pin 31). My question is; is there a fault in the ECM itself causing the current draw or is it one of the components connencted to it. I could isolate each in turn but as they are scattered all over the bike, this could take a long time.
