With the ignition switch in the RUN position, test for battery voltage at the circuit fuse in the transmission solenoid power supply circuit. Refer to the appropriate SI Document for the transmission solenoid power supply circuit information. 2. If battery voltage is present at the fuse, inspect the ignition voltage circuit between the fuse and the transmission for possible opens. 3. If battery voltage is not present at the fuse, test for continuity between the fuse and the ignition switch. If NO ontinuity is between the fuse and the ignition switch, repair the open in that circuit. 4. If you have continuity between the fuse and the ignition switch, the most likely cause is the ignition switch. Replace the ignition switch using the appropriate Ignition Switch Replacement procedure in SI. Refer to group number 2.188 of the parts catalog for part description and usage of the ignition switch.
