Having problems with your Ford Taurus ?

My 1995 Taurus Ghia has a constant current drain (leak) of ~ 1A. Temporarily removing fuse #2 (Juction Box) fom the Engine Bay box, reduces the drain to ~ 0.02 A. Removing fuse # 27 (battery saver) from Instrument Panel box does the same but Power Windows and Interior lights are disabled. What is the Junction box and where is the Leakage occuring? The entire Steering column was replaced ~ 3 years ago becase of a damaged ignition switch. Fully recharging the battery removes the "Service Engine So

Hello, Seems you have done some good work in tracing the problem. It could be a bad Diode in the Alternator, disconnect the plug on the Alternator and see if the Voltage drops(engine off). But the tracing of the problem to the Power Window circuit and Interior lights merits further action.

\012You need to disconnect the Window motor, switches and so forth until you find the grounded part. There were some soldering issues in the Window motors when they were manufactured. The Drivers door has the additional Relay inside if you have the Auto-power feature

\012Your Battery needs to be fully charged and showing 13.2V-13.6V or the Battery is weak. Ford Anti-theft can even interrupt the Alternator from charging while you are driving. The Battery should be checked, but of course you still have the grounding issue which ran down the Battery for maybe Years.

\012I hope you found my solution very helpful in solving your problem.
