Hi,
I both a new Power Trim (PT), ref:855998A05, because the old one is spoilt by the corrosion. Wend the PT is at home, I try to test wiring with 12 v and it works up properly, moving the three pistons, but wend I try to go down only works and go down the middle piston and the others pistons doesn’t go down, I don't know if I am doing something bad or the PT doesn’t work properly.
Thanks
Manuya
