What is the battery voltage?
Connect a meter, turn the lift on, and watch the meter.

man, are you checking any of these parts or just replacing them? The diode blocks are not what i was talking about. there is a diode on the contactor coil.. physically on the terminals of the contactor coil.


does the contactor close then open immediatly? or not at all?

if all the epo circuit is ok, check the diode on the line contactor, make sure it is not giving the coil a dead short. it being on backwards can simulate this.
