The only MTH Premier engines that were vulnerable to the "scrambled chip" problem were the Shay, Big Boy, and the Santa Fe and L&N F3 units. When you replace the dead or dying battery be sure and stay below 10 volts when you try to cycle out of neutral to forward or reverse. The Zephyr did NOT have the chip problem.
