Ok, as the story goes, on the second ride of my barn find 1964 CB77 the battery boiled over and spilled battery acid on my left muffler. I used baking soda and water to neutralize the acid. Now I have alot of stains on the stainless steel muffler.
Can the stains be removed?
I am going to replace the celenium rectifier with a Radio Shack Bridge Rectifier 276-1185.
Thanks
Jerry
Battery acid on my CB77 org mufflers! AURRRGGG!
There is no regulator on these machines so the new rectifier will not solve overcharging issues.
You should be able to polish our the 'stains' where the acid has etched the surface. Try replacing the battery with an AGM type where the electrolyte is absorbed into a porous glass mat. G '60 C77 '60 C72 '62 C72 Dream '63 CL72

Thanks, does anyone have a AGM battery part number, or brand.
The voltage at the battery (attached) at 6500 rpm just keep climbing, I stopped my after the spill test after the readings where going over 15 volts, it only took a minute or so to go too high. What would cause an overcharge problem. Head switch is on, all lights are working. The bike is starting and running great, the weather is getting better, I want to ride! You may be able to save your muffler. Use a fine compound (white or blue) and a buffer with a fairly soft wheel. I have been able to bring back some fairly bad chrome this way.
Unfortunately you are stuck with the same charging problem that everyone has. It is not regulated and you get what you get. I have spent the last several weeks looking for a simple regulator/rectifier to try and solve this problem. It is possible that regulator/rectifier from a Kohler engine might do it. Shortly I will be trying a setup from an early CB500 and from a Kohler engine.
Here is a regulator rectifier combo kind of expensive though
