I had recently been advised by my mechanic that there was a charging issue with my bike. I would like to test the rectifier to ensure that it is not the culprit but alas, every service manual I can find on the '95 CB400 says it is under the rear fairing. But it's not! I cannot seem to find any other information out there on where else they have been located on CB400s before. Any ideas? Regards, M.
