Truck serial # 2GL 01754. Actual model # NRR45. Truck showing fault code 26 at key up. No travel. My service manual not matching up with this particular truck. I followed code 26 procedures in Raymond discussions. Checked for battery short to frame. Showing ok. Pulled drive motor cables and checked for shorts or opens. All checked ok. Inspected all power cables and connections to drive motor. All showing ok. Am lost on where to go from here. Still not certain on code 26 on this particular truck and srial number. Please help. Thank you.
