I get your point about the R&R it came new from ebay. When testing the output from the R&R it only shows battery voltage. The connector plug on the output side all look good but i cant see any fuses?
I recently acquired my 1982 CB750C and can not get it to charge the battery. i have put in a new stator and tested it, getting 15v ac on each of the yellow wires.
I have also put a new regulator/rectifier on but getting no output to battery? The regulator/rectifier just gets hot. I am at a loss...
