Guess I picked Hot Spark 'cause I wanted some new technology, it was cheap on Ebay, and it wasn't Pertronix.
It worked fine for about 2 minutes run time. Then Hot Spark became No Spark.
I pulled my engine to clean (recent purchase) after initial Hot Spark successful install, and once engine was reinstalled, I only got intermittent fire for a few minutes, then nada.
After confirming all wiring wasn't queeped, I yanked the No Spark and put the points back in, and she runs perfectly.
Got an extra set of points to throw in the glove box and threw the Hot Spark in the trash. Hot Spark is not reliable IMO and not ready for the long haul.....my $.02.
No I never reversed polarity and my coil is fine. It's just Chinese garbage and thank the gods I didn't get stuck out in the middle of nowhere.....
