wolfe10 Report post Posted March 9, 2011 Welcome to the FMCA Forum. There are two fuses to the Allison ECU. Check them first. Also, verify that other accessories that should operate with the key on, such as the dash HVAC fan, are operating with the key in the "on" position. If not, the ignition solenoid should be checked.
