""If the video glitches during your viewing, just advance a couple of seconds and will be ok. Sorry for any inconvenience"". Many thanks to members at GMTNation Forum for their suggestions that helped in digging in and finding this cause of my problem. So, in case the original ignition switch, that you are replacing, is geared wrong to begin with & when you match the gear for the new switch, a new or same problem could still be there on the new install. This video explains & shows a way to correct the gear set up for the new switch. The video explains how this problem COULD occur.
