BorgWarner introduced the Smart Integrated Magnetic Switch (IMS) for the aftermarket. Designed for Class 6 – 8 on-highway trucks and off-highway agricultural, construction and stationary power equipment, the Smart IMS is integrated into the Delco Remy 39MT heavy-duty starter, without any additional vehicle wiring required during replacement. Featuring six electronic functions, the Smart IMS protects the starter from potential damage caused by system or operator error. Due to this extensive protection, the 39MT starter with Smart IMS offers a more robust warranty than conventional starters.

Six functions protect the starter from potential system failures—an engagement monitor automatically retries the starter without operator intervention to avoid overheating the solenoid. Rapid re-engagement lockout prevents damage to the pinion and ring gear, running engine lockout averts failures from engagement with a running engine, and low-voltage lockout avoids overcranking and solenoid chatter. Time-limited crank also prevents overcranking, and auto-disengage at engine start avoids extended overruns, the company said.
