Thanks for your reply. For the first code which is 24. I have change motors and fwd, Rev contactor. I changed the Main SCR controller, changed subbers. When the truck start it move in reverse and then when try going fwd it code out. What I notice when I try lift functions it shut down the truck completely. So when I change the card I start to have a thermal issue as I try to accelerate the truck. I change the thermal sensor and the REC1 but still having the same issue. I have no handheld.
