84 318 5th ave. I wanted to keep origional alternator, but it wasn't charging so it got diodes, bearings. It was a poor job and I had the alt rebuilt by another electric motor shop as it made bearing noise. The system is charging at 16 volts at idle and boiling bat. I put on a new regulator and its still 16 volts and boiling. Can the alt put out to much if the reg is good?
