To test the heater coil, it says:
1. Turn the instrument power off.
2. Disconnect the oven heater leads (P3, P4) from the AC power board.
3. Use an ohmmeter to measure resistance at the connectors.
Everywhere else in the document, "connector" refers to the part attached to the board. But how does testing the circuit board test the no-longer-connected heater? I'm I actually supposed to be testing the leads?
