Hi guys,

Just wondering if someone could help me out with a drive fault on this crown? I have a tech working on site away from workshop on the unit. My knowledge on these trucks is very limited. He is saying when the direction handle is moved forward nothing happens until handle about halfway through forward motion then the truck lunges forward then codes out with a 53 error code, truck stops. This is also happening when moving handle into reverse or truck first direction the truck lunges in truck first direction and codes out with a 49 error code and stops. He has fitted a new potentiometer to handle thinking this may have been the fault it hasn't fixed the fault. What do the error codes mean? Any help or advice on this would be much appreciated. Thank you.

Kind Regards
Brett.
