Just installed this to eliminate points in my 68 Chrysler Newport, installed exactly the way it was supposed to be, I ran the red to positive black to negative, I tried starting turned over ran rough shut off, put the original points back in the distributor now I can't start it and keep it running normal shuts off right away, I hope I didn't destroy my motor it ran fine yesterday until I took the points out and put the kit in. Please any help would be appreciated.
