Strange ckicking/relay chatter
Today when I went into the garage I heard a sporadic ticking noise much like a relay chattering.. I opened the hood and it is not coming from either relay center but rather underneath the wiper plastic cover--I think. It is not that noticeable inside the car. When I start it up the clicking stops. When I shut it off It will click for 10 about second's and then stop and then start up again. Everything seems to work just fine. Has anyone experienced this?

Now I feel like an idiot 
Today I had some time to get to the bottom of this clicking since sooner or later something was going to fail.I disconnected the rear battery and the clicking continued. Then I disconnected the starting battery and the clicking continued--WTF how is that possible? Then I realized that the clicking was actually coming from my garage opener and the noise was telegraphing down to my car in the cowl area. Actually that is a relief since openers are dirt cheap compared to SL parts.

We’ve all been there chasing gremlins. You know blind alleys, false positives, two problems posing as one, etc.
