I cant do static tests. My tps is at 0.68, tiller is in nuetral, but i keep getting the “running or in F or R” message. Is the nuetral safety switch bypassed for tbe jet application? Thats the only other thing i can think of, and the tiller handle just interupts power to the key switch? Any input would be greatly appreciated

Is there a problem? Should have a neutral safety.
Im almost sure its been bypassed for the jet application. I can see where one would hook up to the linkage but its not there. On yds it says the nss is “off”, no matter what position i put the tiller shift lever in. I cant do stationary tests since the ecu thinks its in gear.

The neutral safety switch is for start in gear protection. It interrupts power to the starter motor relay if the motor is in gear.

The neutral position switch tells the ECU if the motor is in neutral or in gear. In a jet drive application it is normally fixed in the "in gear" position.
