Dometic RM2652 no power to upper control board

Also I forgot to say right before I took the camper to the campground I checked both the old and new electrode's for continuity from the end of wire to the tip of electrode and got 0 ohm reading on both. I have the original electrode here still so I guess I could check continuity from end of wire to the metal tab on electrode to make sure it is not shorted out. I should be able to go out to campground this evening or tomorrow to do more testing if I need to. Thanks
