Thermocouple short question

I don't understand the short error from my thermocouple.
If I have a thermocouple and a heater connected to the duet but not in the heater block and I power on I don't have a short.
The moment I put both in the heater block and then power on I get a short.
If I connect the thermocouple after being powered on, I don't get a short.
If I put a continuity tester between the thermocouple wiring and the heater wiring there is no continuity anywhere.
What could be going on?
Latest 2.0.3 firmware. Brand new e3d thermocouple. Haven't heated yet.

Have you tried checking continuity between the wiring and heater block?

Seems strange if it were a issue where the voltage of the meter it to low to indicate a leakage but the board does. You don't happen to have a high voltage insulation tester or know someone with one?
And just to confirm, you are measuring the continuity under the same circumstance the board is giving the error?
