Hi keypad,

It's a long time since I worked on an R14 but I have come across a similar fault on one of these before, first check the battery connector,
The main connector should comprise of two male poles that's the truck half and two female poles battery half, check the mail poles for excessive wear, what can happen is that is excessive wear is on poles then the truck running over bumpy ground or hole in warehouse floor can shake the connector sufficiently to spike the power unit and blow it. Then there's the logic unit it has a set of contacts in it that can spring open if truck is bumped. I think you can remove six small pan head screw and remove logic board from the container and reset contact carefully by hand, this may get your truck going. I hope I'm talking about the right series truck as I don't have any written info on it. I hope this info is usefull.

Regards Nero

What controller does it use the black logic card that sits on top of an aluminium base with drive contactors? If it's that one does the drive contactors energise? If not try disconnect the 6 pin plug off the aluminium base unit and if then the drive contact energises but still no drive its a faulty base unit.

If its the older aluminum boxes with white igbt modules below it check the igbts. You can compare the readings with the hydraulic igbts. If you find one to be faulty you should be able to take it out of circuit just to see if it drives.

On the other hand if it's the large aluminium power module then it uses shunt wound drive motor and if your motor checks out not open circuit good chance its the module. However I think they used this on the 2000 plus models not too sure.

I'm guessing you have checked throttle voltage and variation when using the accelerator.

Just remembered we had one with the igbt units that would not drive but hydraulics worked fine. Yet it was an earth fault on the hydraulic motor that prevented it from driving. That was a weird one

Yes I think elektrodrive is on the right track here although I don't know what Igbt unit is I think he is referring to the power unit is but It sounds like the same unit I worked on, these unit secured to the base plate with every other unit on top of them. When you get to them and remove them you will find them heavy for there size. The truck I worked on had four power units fit to it, one fit by a Lansing engineer
Which blew with in half hour of him leaving site. I think it will come down to the power unit or logic unit in the black box.

I think if the black box is in it he is also from readable to read from foud code

Thanks everybody turns out it was a wiring fault found by a Linde engineer even though I hate to admit it.
