No, I would NOT expect full voltage to test at those two points if the contacts are closed, so you have to know what is up with those.
I would propose testing this in a bit different way. One big point of failure on electrical heating is the element as it takes a lot of stress as it swells/shrinks as it heats/ cools.
So I might first set the meter on resistance or ohms scale. The one with the funny upside down horseshoe? Tough the meter leads together to make sure it is all set right and get near zero resistance from one lead to the other. That tests the test first!
Then with power off the the heater, move the probes to each side of the element, like where it is labeled white and black, maybe? The test reading is not too critical and may be up near several thousand ohms but it is usually either good enough or totally bad and you get no reading. Some read really high so try switching to higher meter reading levels if you get something strange looking. All you really want to know is that there is a good path through the element from one end to the other!
Just my method to test the element first but then do test the voltage goes through right.
I might go one probe to ground somewhere, either the neutral or some frame item and then the other lead to the point "A" to see the 110 VAC is getting to the board, then if I can find and reach where it comes out of the relay (like where it says black?), I want to see 110VAC there and if all okay this far, you are seeing voltage go to the board, to the relay and through it and getting to the element. The last step is to see the voltage is getting THROUGH the element by checking where it says white.
And a big point to keep in mind is how much corrosion we get on things that we store outside and may not use for a few months. So all those little quik-connects are always a good place to wiggle and look at them for being clean. You may get voltage all the way through everything but if that last little plug is corroded, we miss the real problem!
