It will just up and die,so I don't trust it. I thinking I have a stator or coil-CD unit problem. Right now it does'nt run, no spark, no lights. I unplugged the single pin wire coming from the engine thats thats i have heard would by-pass the kill and ignition switches but still no spark. I wanted the check out the stator with a ohm-meter before I spent $360 on a coil-CD assembly but can't find a manual with wiring diaghrams and stator ohm specs. Anyone know how to test the stator? The engine is the USA made 600 big block.
