Yes, there is relay
This is helpful. Look at figure 7 for the AC wiring. The 120V power from the breaker panel connects to the relay. Then when 12VDC is applied to the coil (refer to figure 6), the relay should pass the 120V to the switch. Then once the switch is on, it feeds the hi-limit cutout and finally to the element itself.
If you're comfortable checking with power on measure it at each place, starting with the input to the relay. If you aren't comfortable doing that, find a way to connect the meter while the main power is disconnected and only turn it on long enough to read the meter.
If you suspect the outside switch, try temporarily shorting the pins or better yet pull the wires off the switch terminals and find a way to connect them to each other (with the power off).
