From Admin........Thanks Edward t, yes we are intent on saving the knowledge so that it is searchable for the betterment of the industry.
when "forum" software like this was being invented, a 'primary motivational idea' was to be able to harvest and keep knowledge that would otherwise be lost or only shared between a mentor and their student or "around the water-cooler", I hope that is what we are accomplishing here, a saving of the knowledge of how to move goods and materials as safely and efferently as possible.
Edward i am with you on posting thoughts on questions. Even those posts that are years old also. Just by luck a person might could use the info offered at a much later date.
I always think it is best to converse about these types of things on an open forum like this, as it will be a searchable record that may well help someone else at some later point, and if there is some mistake it gives others a chance to speak up and offer their opinions as to the correct procedures and information, but you are always welcome to ask, and it is no bother at all.
you may also wish to include a valid e-mail in your -profile- (the forum software strips out properly formed e-mail and URL addresses, This IS a good thing, as it keeps down the automated 'phishing' for e-mail address, and makes it more difficult for spammers and scammers to automate an attack this forum's members)
Thank you very much for this information :) Sorry about "all caps"/"shouting" :( I don't always pay attn. to that and I should,everything we do on the computer except for emails and things like this have to be in all caps and I sometimes forget to change. I really do appreciate your help,Technician just read this as well and headed to the shop to do some more checks :) May bother you again if alright?? Thank you and have a great day
Sheryl,
-IF- I tell you what the codes mean, will you stop 'shouting', and use small case letters? [Using all caps is consider 'shouting', and should generally be saved for when I say something typically dumb, although this conversation may turn in to 'typically dumb']
My book for this truck shows a truck with GE SX style controllers, (maybe 3 grey boxes if you have the proportional hydraulic controller) codes that have a 2** number will be related to the right traction controller codes with a 1** will related to the pump controller and no number ** will be the left controller.
I don't see any 38 status codes for SX or SEM controllers. ?maybe that was really the 68 codes?
the 266 indicates the right traction controller or drive motor had a failure that shorted the fields, either in the motor, the cables or the controller.
the 68 codes (268, 68) are the right and left traction controllers failing to allow static return to off signal (maybe as a result of the shorted field in the right traction controller or motor)
code 251 is the right traction controller, not charging the capacitors properly, which can happen if you have a blown power fuse (remove to check, do not try to check while installed, false reading is possible) or you are going to need to replace the right side controller.
now to my.02 USD as to why this happened.
This truck needs to have the battery pulled out, charged and serviced by a battery company, all the corrosion under the battery cleaned out and any heavy power cables that have been laying in corrosion replaced. I would also closely check the brush wear on all the motors, especially the right traction motor. You also need to insure the battery lift cut-out is properly adjusted and that the operators understand that if the truck is in a tight spot or otherwise stuck, and does not move at all within 3 seconds of trying to move, they MUST stop and figure out what is keeping the truck from moving, not just try to floor the pedal and shove over or make the wheel spin to move the truck sideways. I think this happened in a tight turn (which is why only 1 controller, the right one, is shorted, it would have been a left turn, most likely backing out of a rack) and more than likely happened at the end of the day when the battery power was lowest [voltage goes down, watts (current load) stay the same, amps have to increase, more amps = more heat].
In this truck (and most with GE SX or SEM controllers), the controllers cook, in some trucks with earlier controllers, the motor would expand the armature and then cook, in this situation.
S/N E807N05888B MODEL ERP040TGN36STE082,THE CODES WE ARE SEEING ARE 266,268,68,251. WE HAVE NO HYDRAULICS,NO TRAVEL...NOTHING BUT STROBE LIGHT WORKS,BATTERY FULLY CHARGED,CONTACTORS CLOSE WHEN PROMPTED ???
a serial number or at least the series would be nice...
