Hi guys,
I was the happy owner of a Linde e12 324 serial: 324511001412/1985. But suddently the forklift won`t drive anymore.

The U200 PCB was damaged, a resistor was destroyed. So I have bought a different U200 PCB from marketplace tried it but it still doesn`t work. Even the contactors won`t switch. I think that maybe one of the BIG thyristors is broken. And the thyristor caused the PCB resistor to burn.

I did a lot of research and measuring on the electronics of the forklift but I can not find the problem.

So I`m looking for advice from you guys.
Where should I start diagnosing the forklift, what parts can cause this problem.

Thanks in advance,

Lambert
