Ok, so heres the deal, I have an 87 supra comp ts6 m. pcm 351 motor. I was out on it last week and it just died. After doing some diagnosing, I found it had no spark. I replaced the coil with a accel 12 v coil. Still no spark. I then figure ok maybe the points are bad, I have already replaced them once. I ordered a pertronics conversion kit pnx-1581 or 2 I forget exactley which one. It is the right one for my application. I installed the conversion, STILL no spark. What could be the issue, does anyone have a wiring diagram for this boat. I checked voltage at coil with ignition in run position, no voltage. I ran a wire from the battery positive side to coil positive side to bypass, still no spark. Bad resisitor maybe? not sure. Also I forget what it is called the little black box on the right side of the carb. it has a positive and negative lead coming from it, could this be an Issue? Any help would be greatly appreciated.

thanks, adam
