>From a previous post: Recent experience with my 84' CB650SC:
Intermittent starting problems, sometimes after just riding and shutting down. Battery condition questionable. Charging system typical low output. I have a multi light voltage indicator from HarborFreight installed so I can see the voltage/battery/charge condition. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=46972 Replaced the battery with a new Honda/Yausu(?). Much better. Replaced the regulator/rectifier with one from Electrosport $100 http://www.electrosport.com/products/product-detail-581.php This made a enormous difference in charging voltage levels. I now get charging voltage @ 12 V + at about 1500 RPM or less, and 14+ V above about 2500 RPM. The Electrosport regulator/rectifier gave me a tremendously improved electrical system.

Sent: Tuesday, May 18, 2010 8:58 PM Subject: [Nighthawk Lovers] Regulator/Rectifier Hello all, I have been chasing electrical problems on my 83 650 since I got it. I think it is mostly just age. New fuse panel, cleaned up ignition switch, lots of dielectric grease. However, I was wondering about the regulator/rectifier. To my knowledge, it's function in simple terms is to smooth out the electrical current generated by the alternator and make sure it is a standard voltage (I know it's more complicate than that, but let's keep it simple for my benefit). My question is what happens when it goes bad? Does it simply fail outright or can it gradually degrade and do it's job less efficiently? If this happens, what kind of symptoms would I be seeing on my bike? If it is allowing too much current or not enough, would this strain the overall electrical system on the bike and lead to problems? I am leaning towards replacing it anyway, I am just curious as the cheapest one I have seen so far is $135.00. How can I test the original part? Thanks!
