I have one cylinder that is not firing. Both coils are charged with 12.5 volts to each other. when i turn the motor over and the one that works fires, it drops to 4 volts then back to 12.5. the cylinder that dose not fire stays at 12.5 all the time. On the 4 small wires coming from the lamp housing I have Red - 7.5v Yellow - 5v Blue - 0 v Black 7.5v . on the next rev I have Red - 7.5v, yellow - 5v, blue 7.5v, black 0v. Dose it look like its cutting on and off or dose it seem like the box is not working properly? I can't find any good info on this thing.
Sorry that I can't help you with Newtronics other than to say that in my limited experience (helping another racer) they either work or they don't. I suggest you change to a different system, Moto-Plat or PVL are good. Pro-Flow has one also that I hear is good. I have new ane used Moto-Plats and new PVL for sale and will be at Talladega this weekend. Lyn Garland
I heard the directions on some were backwards. In other words, it tries to fire at bdc instead of tdc.
