    2016 200 ProXS won’t trim up

    The motor won’t trim up but down; however, it automatically trims up an inch when turning on main power. Serial# 2B123417. TIA

    Not sure if your model has 2 relays (1 up 1 down) but if it does swap it and see if it follows. That's how I determined mine when it stopped. Installed new relay good to go.

    Does this mean that if you turn on ONLY the battery switch, the engine starts trimming up all by itself, without you touching any switch?

    Check for a Trim Limit Module (Ranger commonly strapped them to the PCM wiring Plugs). If your trim sender is not working properly, the tri-lobe pin has fallen out, or the module is failing, it can interrupt "up" trim relay operation.

    Yes, that’s correct and that lasted for one second.

    Trim gauge is working correctly. Switched relays, now both up and down are working. Weird. Ordered two new relays just in case.
