Our service department found a separate unit with loose connections in the transfer switch. This initiated an investigation. After the investigation was performed it was found that the improper tool was being used to attach the wires in the transfer switch which could result in the connections being loose. It was decided on 8/17/23 to continue with a NHTS recall to have these connections checked for proper torque. Description of Remedy : Description of Remedy Program : ATC will supply work instructions and any parts applicable to any damaged components if needed. Work instructions will be sent to the dealers and retail customers. The repair facility will be allotted 15 minutes for the torque check procedure and will be reimbursed accordingly. If a customer or dealer has incurred any costs related to this defect prior to the notification those costs will be reimbursed. How Remedy Component Differs from Recalled Component : Once the torque is checked and torque specifications are acquired the connections would be tight and not be at risk of causing friction to heat up. Identify How/When Recall Condition was Corrected in Production : When this risk was found all trailers on premises were checked and torqued if needed. The process on line was immediately rectified and proper tools were initiated in the on line operation and followed up with QC.
