If I was going to fish walleye I'd want your rig.
I try and stay out of these "What's the best motor/boat/rod/reel/line" discussions because they tend to go sideways pretty quickly.
If you know how to properly use a voltmeter it won't come back to bite you. You'll be chasing your tail on the recommendations about grounding that I've seen so far - identify the problem using the right tools and go from there.
I'd break out the volt meter and start working back from the truck. Focus on one light, disconnect the others, find a good ground for one lead of the voltmeter and see if you have voltage on the one trailer light you have hooked up.
Well they finally got beat yesterday, but overall, taking 3 out of 4 from Detroit in Detroit is not bad. Anibal Sanchez kept them baffled yesterday. Sanchez is a pretty good pitcher that flies under the radar with Verlander and Scherzer on that staff.
Yeah as far as I can tell, he didn't name it after himself. Others have done that for him. I doubt that he gets a buck every time someone says "Ned Rig", well at least not from me - maybe some of you guys are sending him money.
