I have a pair of 1970 GM 427 325hp mercruisers in my old wood boat. They have a semi electronic ignition system with a trigger assembly in the distributor instead of points and a switchbox that takes the trigger output and fires the coil. Does anyone on this forum know how to test the switchbox, coil and trigger assembly? Also, I have been able to find a new aftermarket switchbox and trigger assembly but can't find the trigger assembly any more. Any ideas would be very much appreciated
