That is a four stop solid state card rack controller. Are you an owner, or a mechanic??? Why do you want prints?? What city are you in??

You might have a valve problem.

Think they have replaced valve not sure if adjusted correctly have to look into that also tac the car next te there. Just wondering when u order the solid state boards are they job specific could I have the wrong board for this configuration is there difference between say a 2 stop to a 4 stop on the timer for each of these controls

Cards are not job specific. There are three slot and four slot cards. Higher number of slots will replace lower number of slots, i.e. a four slot board will replace a two or three slot board of the same type. If you have an I-2 valve, make sure the screen in the leveling adjustment id clean.

So the timer pot on the power board there was about 1/8 turn left ,increased that an so far car still running but no more adjustment left.also customer has a oil burner heater in room maybe may still have problems as the weather changes and that thing fires up not sure. But thanks for your help on this johnny

Usually, Dovers of that era had a bimetal sensor or some type of thermostat in the tank. when the oil got cold the thermostat would call for heat and the pump motor would turn on and run on bypass till the oil heated up. Those Dover valves would not move the car if the oil was cold, they would run till the oil got warm enough or the Low Oil Timer tripped. I would check the thermostat before replacing anything.
