Hello everyone, new member here from Ontario, Canada. I have purchased a 2010 New Holland B95B backhoe and the backhoe control switch will not stay lite which allows the backhoe controls to operate. I have replaced the switch with the same results. This switch is the upper switch on the right side pilot control tower. As long as I hold the switch in, everything works, as soon as I let off the switch, everything stops working for the backhoe. This setup is the same as many Case model backhoes as the switch was from a local Case dealer, same part # on the switch. Could this be a relay issue? Any help would be greatly appreciated as this is my first piece of heavy equipment.
