So i have been shooting my 30D with a nonname grip for about 8 months no issues, Suddenly in the middle of a game it just stopped working. Though no problem switched to a canon grip off a friends camera and it did not work.. Here i started to freak out thinking my body died..
Yanked off the grip and slide a battery in and it works fine.. take the battery out and put the grip in nothing. Wiggle it alround alittle and get some life.
Seems i have to put the grip in and twist it every so little to make contacts for it to work ( with both grips).
Noticed that the pad the grip contacts too has little indentations on it from the grips connections and i am wondering is it possible that the pads contacts are bad? I cleaned all the contacts with an eraser and still the same issue.
Anyone else have this issue i really dont want to send the body in for repair this time of year.
