TIM 6 ignition
« on: September 04, 2016, 04:33:47 PM »
I have two TIM 6 ignition modules on my V twin engine. They were both working but suddenly one will not fire at higher RPM. It works at low RPM but as soon as it speeds up it will not work. I assume that one of the transistors is going bad but I do not know. It is not the hall sensor because I can swap the sensors and the results are the same. Electronics is not my best field so I just blindly follow the diagram. Anyone have any insight?

 Gordon,
My only bad experiences with the TIM 6 ignitions is that if the coil doesn't have enough resistance it will overheat the diode. Other than that they have been bullet-proof. I don't see any reason why it would fire at low rpm's but not higher. To me it sounds like there isn't enough dwell or saturation time at the higher speed and the coil can't charge.

It is cutting out at relatively low RPM. Like 50 RPM. The one on the other cylinder works fine. I will try switching out the coil.
