Tht unit should have a 100% pilot safety, so if it stays lit the thermopile generator is okay. The first thing to check is the pressure switch that determines if there is flow through the heater. Jumper its terminals and if the heater starts, you have to determine whether the flow is too low to operate it or if the switch is defective. To bypass all the controls, jumper from the millivolt terminal that goes to the controls, over to the terminal where the return wire connects back to the control. You should also slip the connectors off the controls and clean them since even a slight corrosion will prevent the flow of electricity to the valve.

:, I bought a house an inherited the beast. The pilot light lights and stays lit. I'm thinking the Millivolt Generator is ok, but it maybe worn out, how do you test it, or jump over the connections to see which electrical parts are spent?

: What are the logical steps to go through?

: Can parts be removed and taken to the hardware store for testing?

: Or should I just rplace all of the electrical stuff?

: The water flows through it ok.
