Re: [Psychonaut] XTi firing when turned on - tongue switch
Sounds like a short in the cable, connector molding, or switch. Easiest diagnostic with no science involved at all is to just get another tongue switch (or any sort of remote control, which you might find at Best Buy and could try out in the store for free) and see if it happens with that one too.
If it DOES happen with the 2nd switch... then you have probably serious problems. But I'll bet it doesn't.
Side note... trying to plug a switch in while the camera is on most likely will cause at least one shot to fire as the plug slides in and temporarily crosses contacts. Always plug and unplug while off, for the sake of convenience.
