Inside the clutch is a diode ACROSS the coil windings. Wired properly, it shunts the reverse current from the magnetic field in the clutch when power is removed.
If you ground the wrong wire from the clutch, the first time you energize it - you feed a dead short to ground through the diode. Most of those diodes are only rated 1.5 to 2 amps. When you nail the diode it often fails shorted. Then you have a built in short across the clutch coil.
Your aftermarket plug has a second diode from your description. Is it wired across the two terminals in the plug?
Yes. I wish I could post pics here but it is a black diode with a silver stripe on the positive feed. Although the connector is different, it looks like this and is wired the same way. http://www.casperselectronics.com/cart/ ... uct_id=296http://www.casperselectronics.com/cart/index.php?route=product/product&path=7_53_54_10_13&product_id=296
