7531 crank trigger signal

I've got a 7531 box and I'm having problems with it. I'm wondering if anyone is running a crank trigger setup besides an msd setup. I have a reichard racing crank trigger and pickup. I have no spark when I try to start the car but when I follow the diagnostic sheet to check for spark I have spark. I just got the box back from msd for repair and they said there's nothing wrong with the box. Before I sent it in the car would not idle. It acted like it was on the rev limiter under 1500 rpm but over 1500 rpm it worked fine. Anyone have any ideas? Nick

What is this MSD tester you speak of, delltang?

bushmec, I did their spark test and I do have spark. I believe it is a bad signal for some reason. I am going to recheck it tomorrow night after I move the pickup in some. Its at .065" now. The weird thing is that it would not idle out of the box, but it would run fine above 1500 rpm, but I guess that makes sense. According to MSD the higher the rpm the stronger the signal. I will let you guys know what I find. Check the polarity of the magnets in the pickup? MSD recommended that as well. I have to find a magnet with the poles identified on them. Thanks for the help.
