I have an M1123 with a wait to start lamp that will not turn off. Initially came into our shop for a body wiring harness. After we noticed the wait-to-start lamp wont turn off after troubleshooting, we eventually replaced the PCB, glowplug controller, glow plugs, and the engine wiring harness. still no luck. Has anyone had this problem? The toughbook has no troubleshooting procedures for the wait to start lamp staying on, only for it not turning on at all.
