I checked voltage across contact, 24v on top and on bottom had 20v. To me I am reading the drop though the resistor that hooked up in parallel. I took all wires off the contact and energized it. I took an ohm reading and it read o ohms so to me it should be working right. What do you think if I just jump the batt voltage across the contactor. Everything should work? What would happen if it did not work. Would it then be a bad power pack? It seems to me if I place to B+ from the battery to the other side of the contactor I should at least get the horn and lift out of it. I will pull battery pack and test each battery to see what I get. I will recheck the wire to the contactor coil also. Thanks for feedback on this problem and a reply.
