Arrived at location on 10/22/21 - Arrived, stated unit is dead, not turning on at all. Turned unit on, turned hood on. Checked voltage, traced back through fuses, fuse block. Not getting voltage to power supply board. Traced through up to hood and back down to terminal blocks. While moving wiring and reconnecting terminals, now have voltage to power supply board and unit now turns on. Check ops, functioning correctly. Likely just a loose connection that is now corrected. Ok for use.
