Check the E-Stop switch wiring.Note: If a remote E-Stop has been installed, it must be a "normally closed" switch. If a "normally open" switch has been installed or if the switch is faulty, the EMCP controller will constantly be in stop mode.

Check the Crank Inhibit Switch wiring.
Check the Starter Motor Mag Switch (SMMS) return wiring. Check for damage on the jumper wire between X2.1:33 and X2.1:35. Check the wiring between pin 42 on the C1 connector and X2.1:35. Check the wiring between pin 24 on the EMCP controller connector and X2.1:33.
Check the crank output between the EMCP controller pin 51 and the remote start pin C1-29.Note: The remote start is for the start command to the engine ECM.
Check that the jumper bar is installed between pins X2.1:3 and X2.1:5 if dual starters are not installed. If 24V (+) is present on C1-29 while the controller indicates cranking, the issue
