Anybody that has fisical information about nrr40 that can get in contact with me? Need the book! Serial # 2GL07349
Yeah swoop kinda what i thought. was just giving him a easy check starting point. kind of tough without the book
Peavey,
it could be the field's in the motor but there are other things to consider as well that are part of the field circuits.
- FU8 which is the 150A B+ field wiring motor circuit fuse located on the contactor panel.
- cables from field windings to field wiring assy
- field wiring assy to H-bridge Control Module (HCM)
- HCM to vehicle manager
- field wiring assy T1 - T4 (base leads for TM1 and TM2)
- TM1 or TM2 may be bad
- HCM may be bad
- VM (vehicle manager) may be bad
- drive motor may have open circuit in windings
YOU WILL need the service manual for the correct procedures and test points to correctly diagnose and test these circuits and components.
the code has to do with the fields. check cables and wires and test/check motor
I am not the original poster, but I am getting the same error code. The machine SN is 2GL05855. Are you familiar with the Field transistors? Supposedly they are bad, but when tested for continuity with a tester each transistor reads correctly for each direction, perhaps they behave differently under load.
serial number is a must on this one, so we know what system it uses..
Please. I have same problem that equipment Nrr40.
in the display show me code 26
the forklift cant advance
please , help me
