There was an episode of Jay Leno's Garage where he talked about where the future of car restoration was going.
It featured a Duesenberg that was 80 years old that a guy was restoring back to mint in his home garage. Parts that he could not find, he was able to fabricate in his garage. Jay commented good luck trying to restore any modern car 80 years from now. Electronics would be impossible.
Part of the reason I heeded the forum advice to have an extra RCM, camshaft sensor, and crankshaft sensor.

Ambulances here in the 1980s were Motorola radios. We got to know the tech very well as he was there at least once every 2 weeks to repair a truck.

Going further back I remember my dad testing tubes at a local store for our TV when something went wrong.
Whenever he opened up that TV all I could think was what a mess and potential disaster zone.

Been to quite a few electrical "incidents' over the years. I have a healthy respect for that stuff.
Be careful with your hobby, but you already know that.

Thanks again
Jim
