Weak spark 3-4

[ekvh]

I have weak spark from the Dyna and no spark from the coils. Timing with the light on the Dyna gives a nice bright light on 1-2 and a weak light on 3-4. I swapped coils, but they were good. I put in a new coil, no change. I have a spare Dyna module, I'll swap unless someone has a better idea. Seems as though the Dyna is only putting out around seven volts on the yellow wire. Not enough to fire the coil. Thanks in advance.

I'm using gl1500 coils. This happened after I did the relay to coils. I checked that and I have it wired as shown here.

swit the wires at side cover to switch witch modual is working the 3and 4 ...switch plug wires from front to back and see if problem moves to 1and 2 ...if it dose it diffinitly dyna

Spark amplifier modules would be my guess

Just a thought - hope it helps

I tried several wire swaps before swapping Dynas and it must have been the Dyna. Thanks for the suggestions guys. Time for a ride.
