I was working under my 5th wheel today and my sewage tank was exposed. There is one probe by itself with a white wire and on the other side there are three probes with different coloured wires. When m...

First, turn off the power so that nobody gets a shock or electrocuted and don't use the FW again until the problem is diagnosed and fixed.
You could try a non-contact voltage tester (NCVT) but it sounds like there is a "hot skin" condition.
Below is a wiring diagram for the monitor panel and level sensors that are commonly used that have button sensors/probes. The monitor and sensors operate on 12VDC so there isn't 120VAC introduced through that. The lowest sensor is grounded though so would be at the same potential as the frame and anything else that is connected to ground.
If at home, likely a faulty extension cord or shore power cord. There are other possibilities. As mentioned, google "RV hot skin". Good thing that you inadvertently discovered this as a hot skin is dangerous.
