One of the motors on my ace lift is not working. Standard worm drive twin motor and drum switches for each. Forward and reverse hums but motor wont start. I can spin the pulley to let boat down easy by hand so with motor humming I did that and the motor starts but never reaches full speed because it's like someone is flipping the power on and off every second or so. The motor is a real PITA to get to and worse than that are getting the wires down with the boat in the way. I took the cover off the back of the motor and wiggled all the connections. havent been in the drum switches yet but think because it hums for up and down that unlikely in the drum switch or connections in motor for that matter. The motors got wet (pretty sure they were submerged for an hour or so with some brackish water) during katrina along with the wires and switches but I think my dad, the engineer, replaced the switches and hes not here anymore to diagnose the motor problem so I'm reaching out to my extended family. I'm thinking if anyone here has got a line on good prices I should replace both motors and keep working old for spare.
