Gentlemen, A few days ago I replaced my ignition barrel as it had basically fallen apart, coming out of the housing in 3 pieces. I called a locksmith to do the actual replacement and he ensure it was all working properly. I did the disassembly and reassembly of everything else as I've done it before when changing the ignition switch, but this time I accidentally split open the slip ring housing, which caused the spring to fall out. I put it all back together and it ran fine for a couple of days before stranding my wife in town. The key would turn and the dash would light up but there was no ignition at all. I drove down in our other car, pulled open the slip ring, wiped around it in case something was gumming it up (the locksmith had used WD40 or something to grease the new lock), put it back together and hey presto, it fired up fine again. This morning, however, it wouldn't fire again. I rotated the top of the slip ring housing a bit and it fired up. This made me wonder: Does the spring in the slip ring have to be sitting a certain way for it to connect? I noticed there's a small notch in the inner slip ring (could be the face of the barrel), is the end of the spring supposed to sit in this? I also noticed that a pin near the head of the key slot seems to sit in place and stop the key being inserted if I rotate the slip ring to a certain point.
