Linde e12 324; NO drive forward/reverse, powersteering and hydraulics work.

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

Hi pablo,

I added an arrow in the picture that points to the resistor that was broken.

Hello, can you send a photo of the damaged electronic equipment to begin to see where the fault is located?

Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
