Greetings: Amateur here, but with 50 years of electronics history. This circuit board is for a medical adjusting hospital bed. It has eight relays (24v - model no. 1055030). They are very basic relays. When testing them I get continuity across both poles with no voltage applied. I would expect closed on one side and open on the other and then when voltage is applied I would see the reverse. Anyone have knowledge on this symptom? A little more information on the board. 3 of the motors on the bed work OK. The fourth motor either has bad relays or source voltage for the relays from the processor is missing. Bed has 4 separate motors, 2 relays per motor. At this point I'm just trying to clear the relays as the problem. Many thanks!
