We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common !
through process of elimination (swapped out everything except the sensor with no change in results) i now believe the sensor is the culprit. tonight, when i hooked the timing light to the coil/dist wire while cranking. it only showed a couple of sporadic flashes and then stopped. the good stb motor shows a consistent flash.
the module is a pertronix, 2 wires out of the sensor and pickup that is mounted under the rotor. no paperwork came with the boat for the pertronix. the dist has no munufacturer stamp or tag on it. there is a
"L362" stamped on the base exterior. the plate inside has 25979A LH stamped on it. from memory (the books are at the boat) the rotor number is 302 and the cap is 407. all on a 427/300hp chris craft. i'm more inclined to believe someone here has the correct model number than trusting someone in a auto parts store.
oh, and i tried the stand alone coil theory i suggested earlier, and it did produce a spark.
