Ah...horse feathers. I have been converting points vehicles to electronic ignitions for 15 years and have never had one break yet. And that includes 2 BMW high millage motorcycles, and my truck (pertronix) which has been doing fine for 2 years. I have never had electronic ignition go out yet on any vehicle I have owned. And I had factory units on a suzuki rotary (wankel) motorcycle (RE5) from 1975 and a 82 honda turbo bike (CX500 Turbo) and a 1977 Ducati 900 GTS (italian bike) - all of which were supposedly unreliable.
(then again, mebe I just lucky)
