the truck fails at plugging ocasionally and if you keep the accelerator grip at full speed after the directional contactor has tripped due to the aforementioned fault then the battery indicator lit bars at the display dissapears. the truck goes back to work after cycling the key switch wich tells me is not wiring related ,is not my style to throw parts at a truck randomly but I'm lucky enough to have two identical trucks so I swapped distribution panel,control card, contactors, pot and switches!! my atention is now on transistor panel, I ordered a new transistor and will check those capacitors ,there is also two diode modules there and some snubbers... anybody out there had any trouble with those transistors? thanks in advance!!
