Did you do any testing of amps output from the coil? Sounds to me like the classic change to EI and the accompanying different dwell time, compared to points, slightly changing things and causing issues for the coil. For me failure was caused by simply removing a few feet of wire and a connection. A few tests and use of Neil's formula may be useful.
