Voltage spikes that an older system would ignore do weird things to solid state electronics. In the early 1980's I was teaching a 2-year professional level auto mechanics course at a Tennessee state trade and industrial school (last stop before a permanent spot on the welfare rolls for a lot of my students) and teaching sophisticated electronics to people who were GED-level on the education scale or just slightly above was a challenge. That's about the time auto electronics started getting very complex- - - -computer-controlled carburetors, delay wipers, memory seats, electronic climate control, electronic cruise control etc. After 8 years of fixing autopilot and compass systems on B-52's, all that was pretty basic stuff for me, but the auto industry was in a panic!
