in THE MAIN WALL
how can I check the resistance of the power unit in a gas control vavle to find if it is defective, in or out of a boiler?

    are you talking about the electromagnet that holds the standing pilot valve open?

    t-couple test

    Jack I used to know the method for this test but I can not find my notes. What I can tell you is thatthe Thermo couple should be putting out 20 to 30 millivolts while disconected from G.V. (use a tool to jam the red button down while testing it). If thermocoup is good but the pilot will not stay lit when re-connected, the power unit is bad. When I am troubleshooting I like to find out what's not the problem, and that will narrow the possibilities down.
