Re: Onto a new learning curve…CD ignition

[johnyrude200]

Question. If you see weak spark on one cylinder and none on the other, is it possible that there are 2 faults; 1 at the powerpack (or that ignition coil which has no spark) and the 2nd being a weak charge coil?

If there is a weak charge coil, will the powerpack just shoot off a weak spark to the ignition coils (assuming there are no ground issues)?

I ask this because seeing a working CD ignition, there is bright blue spark jumping in most cases 3/4 to 1 inch. In weak systems, I’m seeing it still jump that far, but it’s barely blue or even orange, or just a smaller gap.

For what it’s worth, the old magneto point & condenser system, completely rebuilt with new wires, boots, etc, I’ve been seeing them go 5/8" with bright blue spark, maybe even 3/4 inch. Pretty darn powerful for things that were ‘obsoleted’ pretty much by the mid 70’s (with exception of the small motors up through the early 90’s…was interested to recently work on a 2hp, 1 cylinder OMC from the early 90’s with a points/condensers system still).
