Testing the power supply

After purchasing new probe tips for my multimeter I tested the power supply at the connector to the solenoid driver.

I am getting power where it is supposed to be but the voltages are not right:

when I check pins 4 and 1,2 ... I get 12v which matches the circuit diagram
pins 4 and 12 give 33vac instead of 24
pins 4 and 13 give 27v instead of 24
pins 4 and 15 give 5v. Matching circuit diagram

So its off to the forums to ask if this is the problem or no big deal and it is within tolerances
