Asking for a friend. He is installing the electronic ignition system (2 CD boxes/4 coils) on a new a Titan 340 engine. The engine was built up at a local shop and was successfully test run using the Light Speed boxes.
With the engine installed in the aircraft, he can only get a spark from one position on the CD boxes.
He states-“When I try to do the phasing procedure and rock the prop back and forth at TDC/BDC, I only get spark across the tower of one coil. If I swap the primary ignition wires around the 4 BNC connectors on the CD boxes, I consistently get spark on whichever coil is attached to just one of the four.
Similarly, if I swap the input 15 pin connectors between CD boxes, I get the same result. To complicate things, I have, on rare occasions, got a weak spark from coils attached to two other BNC connectors.
Anyone else experience issues like this with Light Speed?”
Cheers, Tom
