Angry P0459 Code (EVAP Problems)

Hey guys, was hoping I could get your thoughts diagnosing this code. Iíve been trying to fix my small EVAP leak and just replaced the purge control solenoid (under the hood) and am now getting a high volatage code for it.

I took my multi meter to it and found the follow:

- very small resistance between harness terminals (35 ohms I believe)

- 12 V coming from one terminal and 0V on the other with the car off

- cycling 4.5V on/off from other terminal when car is on and in test mode

- stripped the cover from the wires about 5 inches to look for shorts and didnít find anything

- car throws a high voltage code when harness is plugged into solenoid and a low voltage code when itís unplugged.

Am I correct assuming there is a short?

Also on a side note is it possible to just disable the EVAP codes completely? Iíve been chasing this issue for 5 months now and getting nowhere.
