Looked through the manuals but could not find any electrical schematic of a gas water heater.

Anybody have one? I have looked at several Royal Coaches but none are like the one I am working on.

The control board has all of the components visible unlike other units that are encased with a protective molding.

Two wires come out by the relief valve but the control board has only one spade for a single wire.

Also the igniter has been disconnected and loose in the compartment.

Any help would be appreciated!!
