On my sons 78 550K I am not so sure it is charging the battery properly. I checked back (with a electrician's help) and an getting 12 volts even when revving to 4000 or more rpm's.
The electrician then checked the rectifier for continuity and got nothing. I am assuming the rectifier is no longer good. I checked and saw the price for a new one and it was 220 dollars.
Are there other rectifiers out there that anyone can recommend or is the Honda the only was I should go?
Thanks
Mark
