Refer to the following article.Description of Change: Circuit protection for the engine ECM has been moved to the circuit breaker for the engine start switch.Adaptable To: This change is effective with the following models: 725 (S/N: AFX551-UP), 730 (S/N: AGF539-UP), 735 (S/N: AWR275-UP), 740 (S/N: AXM455-UP), and the 740 EJECTOR (S/N: AZZ269-UP).Formerly the engine ECM was on the same fuse as the heated seat, differential lock and the heated mirrors. The wiring to the heated mirrors is vulnerable to damage. If the fuse separates for any reason, the engine will not start. If the engine is already running, and the fuse separates, the engine will shut down.
