Pacemakers and Model A ignition systems

[Cool Hand Lurker]

I got one in 2008 and have had no problem driving Model T or Model A. But once I was pushing hard on a 1/2" drill that was close to my shoulder and that did affect it. It shut down for awhile and I had to sit down for a bit until it self-corrected. I have not tried arc welding since I got it so I can't comment on that. My sons now have my arc welders.
