Thanks for Posting a great article. I did all of this and seems great ! However

When I shut my Car off, I hear "Click....Pause "Click"...pause..."Click... I put my thumb on the Duo-valve and besides it being burning Hot, The Valve doesn't stop "Clicking "...It actually I think killed my battery after not driving the car for a week.

I pulled the fuse and it stops, left the car 2 weeks battery is no issue...

*NOTE: I followed your easy directions because the Duo-Valve was making this sound Prior....

Any help would be appreciated
