Hello all,

I have the following:
Model: Nichiyu FBT 13 PN-50-300
SN: 215AA0011

It has worked great for over a year, but recently started acting up. When engaging the foot pedal in forward or reverse, the machine will jump forward or backward and immediately shut off. All other functions such as steering and mast are fine. If I release the pedal and press it again, it jumps again. I used this technique to limp it out of the way on the floor. If I continue to hold down the pedal, nothing more happens, but I do hear a faint high pitched tone that goes away when I release the pedal.

On the display the "travel" icon is flashing. Based on some googling, I believe this means, "When fault is detected in the travel circuit, the travel icon flashes and the presumed defective part name is displayed." The display is in Japanese, so I can't make out the part name. I found a post here on changing the display language, but it was for a different model. I haven't dug in yet to see if it will translate to this machine.

Battery is fully charged. I have lifted the drive wheels off the ground and tried to engage with the same results. I'm fairly handy and would be comfortable troubleshooting with my dmm if someone could point me in the right direction.

Thank you,

-Michael.
