Will not move Forward. Reverse works. No codes

Lift was overloaded and completely shut down the lift. Would not turn on. New system card fixed that issue. Now it will not move forward. Only moves backwards. Tried replacing power card, motor wires, both diodes on the traction heat sink, Q1 is new, regen heat sink has been replaced not too long ago. Motor will engage forward if wires are swapped around.

Have you checked the field transistors? Switch positions see if you gain fwd and lose rev. They are what switch directions of current flow.

Speed is set at 7.5
That has also thrown me for a loop before. I had to triple check to make sure it was set at jax speed.

Did you check speed settings? Often the swing reach cards come programmed to 0 mph travel speed and can throw you for a loop until you figure that out.

Fact of the week
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.
