Aquahot 450D not working on Electric side

Been out on the road for the past four months, primarily using the Aquahot Electric hot water system for showers etc. Yesterday it quit working. Still working fine on the diesel side, but nothing on the electrical only side. The panel shows no issues what so ever and appropriate lights are green. I understand there is a high limit reset switch ( which I haven't tried yet) but not sure what the issue might be. Any thoughts would be greatly appreciated!

    I just last week replaced the relay for the electric side on my aquahot. I saw on Roger Berke's website that they had a new relay conversion to replace the original one on my DP.

    I used the schematic he emailed me and removed the old relay that had badly burnt wires, one was burnt off completely. Upon inspecting the schematic it wasn't even wired correctly at all, reason for burnt wires I guess. I had never used the electric side before this. Rewired relay and tested voltage to the element and now works great.
