Marty, thanks for the advice. So I cleaned the boost brake wheel assembly with plastic safe electrical contact cleaner QD by CRC. The controller is working but I still have some gremlins. The controller will revert to CAB1/TMCC mode even with Legacy engines that are programmed in ? I got my new v1.60 or V1.61 modules today from Lionel. My Legacy system is currently at V1.52 both controllers and the base.
After reviewing some Lionel support technical information, it appears that the CAB2 in question may not have gotten the required factory upgrade by Lionel. It doesn't have the Silver paint mark in the left hand battery tray location. Ironically is appears to have a small 1/8 inch diameter silver paint mark in the recess under the battery cover removal tab. Don't know if that signifies that the factory upgrade was done or not. My other remote that is working well definitely has the silver touch up paint in the battery tray under the Left hand batter position.
Cleaning the brake boost controller wheel/rocker made all the really ugly flashing red LED's go away, so thanks very much for the tip. Chris
