I don't mind sending the plane ticket, it's the cost of the inevitable drinking that concens me

w00t! packing my bag...beers are on me!

In all seriousness, wish I was closer, I like these kind of problems.

I think this will get you there. I wire wheeled the area of the frame where I placed my grounds, bolted the ground eyelets to the frame and then painted over them for rust protection.

If your temp switch is in the rad you need to ground the rad to the frame its being insulated by the rubber mounts

That was it guys, the ground. I'm amazed that the rad support wouldn't have a good enough ground but apparently it isn't any more. I put a jumper from the upper control arm to the ground and the fans started right up. A lot of aggravation for a simple thing.

Thanks again guys.
