[LW] [LW11] ST7000 ACU internal voltage drop

[LaurensenKitty]

Hello,
After a couple of clutch failures I measured voltages throughout the system. There is not the correct voltage present at the clutch terminals on the ACU (voltage drop of 1,5V between course computer power supply and clutch terminals). The FAQ says in that case then the course computer is faulty and needs to be serviced.

See attached picture

1) Has anyone encountered this problem and was able to resolve it?
2) What kind of servicing is required?
3) What parts do I need?
Best!

Dear Laurensenkitty,

Thank you for your post.

What is the power input voltage you are seeing?
What is the power output at the clutch you are seeing?

The ST7002 is a control head, what is the model of the course computer and I can check with our service team if we are able to repair the unit.

Many Thanks
Louise
