Alternator wiring questions

After a while of investigating I seemed to have fixed both issues.

- The overcharging might have been a ground cable not connected properly between the alternator and the water house. I reconnected the cable and cleaned the connection as I couldn't make out any metal, just engine block paint.

- The starter was a connector from the alternator going into the inside of the car, where they are connected at the engine bay wall. The yellow starter signal cable was right next to that one and they must have touched. It seemed like the alternator cable was a little burned, probably from overcharging and getting hot first.

So far everything seems to work fine. I also connected the charging cable straight to the battery. It starts much faster now too.

Thanks again guys!
