Hello, I have been to a few Hyster J1.80XMT trucks recently that are all suffering with water ingress into the AC drive motors and throwing up codes. A strip down of the motor, clean out the rust and replace the encoder is fixing the fault - but I cannot see how or where this water is getting into the motors. Would like to be able to prevent ingress to avoid future issues.

Any ideas? Common issue on these machines?

Cheers,

Dan
