TCM FB25-7 Buzzer & rear lights always ON

Hi,

Working on a TCM FB25-7. It reverse alarm and reverse buzzer is always on and the left side indicator are as well even on the switch off position.

any idea what could be the fault. I think its the CPU board faulty at rear panel..? Does CPU Board control all the lighting circuit or the controller fitted in the right side box where integral charger fits?

Thanks for help. if possible please send wiring diagram. Thanks

module FET UNIT is on the right at the bottom, if you open cover you will see a block VTM in a metal box , the back side of module VTM is FET UNIT module. CPU board not need to touch.

little bit confusion, is it the board when we open the right side cover and it is located near the front right wheel in the corner. this forklift has external charger so it is the only card fited in the right side panel.

wires from light switches etc comes to the controller at rear panel (in Counter weight) bottom controller which is called CPU board.

I am sorry but I do not know the catalog number, since I do not supply parts.
module is called the "FET UNIT".

your board "light" defective.
necessary to replace two transistors 2SJ380.
unit is at the bottom right, the back side of the module VTM (where the charger).
