FB15P-50BC-450M - Technical Troubleshooting discussion in Forkliftaction's forums

Nichiyu (& Nyk) FB15PN50:
FB15P-50BC-450M

Hi. I have a problem with the FB15P-50BC-450M.
when the accelerator is slightly pressed the forklift jumps violently (like full speed is applied - there is also a big spark on the relay) for a fraction of a second and then stops. Is there any diagram or any help so I can troubleshot?
Thank you.

Hi Mark. I have order and change the thyristor, checked all the big diodes
and they measure ok. But the problem is still there.
Is there any other info or diagram available?
Thanks for your help.
Yiannis.

Hello Yiannis, I think you have a problem with a diode or thyristor. I can send you diagram if you mentioned your email.
