Thanks
My car has an automatic transmission.

Hello, thank you for writing in. You were right to look for a short in the system, but there are other causes for excess power in a system. The ignition switch itself pulls power from the charging system and the battery. If the ignition switch is new and the problems are persisting, then the charging system should be inspected next. You will also want to check the power supply to the ignition switch. If you have a voltmeter, you can test the alternator to make sure its output is being regulated properly. If the charging and ignition systems both check out, look to the fuse box for signs of issues. For more diagnostic help, contact our service department to schedule an appointment.
