Hello, Anyone,

I've had several failures over recent years, and all were my own fault. Every one was an attempt to fire a battery-powered camera with dead or no batteries in the camera; a Pentax ZX-M jammed in a dry-firing attempt but came clear when fresh batteries were installed in the auxiliary grip; some jams didn't clear with fresh batteries installed [Pentax ME-Super, Pentax ME-F, both when dry-firing, so not affecting any shooting sessions], and a Canon T90 that I'd left unattended with film and batteries for way too long came alive with a replacement set of batteries, but discharged the replacements sitting idle for just a couple of days, and now won't power up even after I hit the camera body's power contacts with a wire brush and 91% isopropyl alcohol.

Thanks and regards,
