2004 Chevy Malibu-issue with doors locking and unlocking by themselves. Reset battery and doors are working now except for door locks on passenger side you cannot manually unlock doors? New issue is...

Hi Shannon,

My guess is that something is shorting in the lock control circuit. Sounds to me that your passenger locks are constantly energized in the lock position, causing the battery drain.
This is likely not involving the computer. A good electrical guy can find it pretty quick. Meanwhile, envision that you have little electromagnets energized and hot. These would drain the battery fast. Disconnect negative when not using the car.
Consider unplugging the lock slaves inside the doors until you get a chance to get in at a shop. By slave I mean the actuator that is energized, inside each door.

2008 electra glide battery draw, test light pulses, now bike wont crank over

The pulsing could be the alarm module. When bike is turned of, you will get small draw for a minute or so and then it should go very low, below a miliamp or so. This is the alarm module setting itself. Check for this. Is battery gone flat while checks were being made? Make sure ignition switch is on when disconnecting battery if alarm (Stock HD) is fitted. If not, alarm module gets confused and can cause problems. The corrct procedure for disconnecting a battery from an alarm fitted HS is - alarm off, ignition switch on, pull main fuse (Maxi Fuse), disconnect battery. To fit, ignition stitch off, connect battery then install main fuse.

Ok if you have a multimeter, set it on 12V and hook it up to the negative side on the terminal and the battery and it should read some volts, what that means is that there is a draw. Now while the meter pluged pull one fuse at a time and see the meter, when the meter drops to zero that is the circuit at fault, let me know how you make out.
