Komatsu (Fiat) FB25H-1R 48volt Year 2002

Hey there,

This truck gives a fault ( V.COND ) on the display.
The maincontactor stay's open.

This electronic is not Komatsu, I think it's Fiat!!
The controller is an Drive and Pump in one.

Is there someone who will help me?

The ser.nr. F14007n00122

Cheers

I only have some error codes on paper. I don't have any further information.

I think you should first ckeck the power transistors and capacitors of the controller.

Regards,
Manuel

Hi, Thanks for your information.
Do you have a wiringdiagram of the controller?
So I can find the error.
By the way the battery is good.

Thanks for your assistance!

Hi,

The komatsu FB XX-1R series have the same controller that the FIAT EU series.
VCOND!!!! means : shortcircuit protection at the start stage. In other words, you have a shortcircuit somewhere or a drop voltage in the the battery.
