I have a small manlift that operated fine this past summer but not now. It has an electric motor that powers a hydraulic pump and a transformer setup that reverses the electric motor for the up or down movement of the hyd cylinder. The motor will only slightly hum right now but will not operate.
On the diagram I've labelled a circle as the "Reverser" but I don't know what kind of transformer it is. I have unhooked and cleaned the four connection points but again no change. I believe the yellow Up/Down switch is run on DC and I suspect that's why there is that other small transformer present.
Any ideas on how to verify if the main "Reverser" is the problem? Maybe I should pull the motor??
Thanks
