I have Falkons with resistor plugs-- and ZDZ ignitions with out resistor plugs and with resistor plugs th stock ZDZcap has NO resistor in it - -- no glitches - ever
my radios are all JR PCM on Ham Band -have been for almost 20 years .
I put the DA cap on the one in the picture it works perfectly
Don't know why the other glitch problems are occurring
