Msd 6al install. Now over charging

It’s a 69. Originally a 273 car. It wasn’t over charging before. (That I know of). I did replace the alternator right after the first ignition module went bad. The reason I went through the msd stuff is because I was having a problem with the connection at the ignition module which caused me to think it was bad


I have had some problems with the switch. Some times I have to kinda jiggle it to get the gauges to work. Sounds like I need to start there.
