Oldgit. Thanks for the help ! Here is another reason for high voltage that was given to me by a guy who was a dealer tech. in the 70's ! THE PROBLEM COULD BE IN THE HEADLIGHT SWITCH. NOT MAKING CONTACT TO SEND THE CURRENT BACK TO CHARGE THE BATTERY. IN THE DAY IT WAS VERY COMMON FOR THAT TO HAPPEN. THE CONTACT BOARD WOULD " BOW " , THE PLATE THAT MOVES FROM ON TO OFF WOULD NOT BE MAKING CONTACT, THUS ALL THE AC CURRENT WOULD FLOW TO THE HEAD LIGHT. DO THE TROUBLESHOOTING WITH A VOLT METER. I THINK ONE WIRE WILL GO TO THE REGULATOR/RECTIFIER. OR MAYBE THERE IS ONLY A RECTIFIER. THE BATTERY HAS TO BE " GOOD " TOO!

cursory regulator So, maybe this resistor is shorted and not providing any resistance to keep the voltage in check ? proper 6v regulator Maybe a new 6v 1 wire regulator that grounds to the frame or an in line regulator ? Thanks So, Very Much !

Looking to set up classes for a general street and street/trail motorcycle show. We have had a cruise in for like 5 years which is growing and I would like to expand to give ribbons and possibly trophies. I would like to include classes such as Touring, Cruiser, Rat Bike, Trike, Sport bike, Vintage (20+?), Antique (30+?), Highest Mileage ect... with American and Metric bikes. Please give me your opinions and remember I feel it would be best to make this a general show but, not get too many classes ? If anyone has a link to such rules and or classes please send them to me. Thank you ! Chuck S. [email protected]

Wow, you are right there is no voltage regulator and I see a diode in the epoxy so, it is a rectifier ! Maybe, I will put a 12 volt regulator on the lighting circuit and use a 12v bulb and be done ? Thank you !

________________________________________ Hello ! We have a silver 1972 Yamaha RT1 360 with a 6 volt system which puts out 11.5 at idle to almost 16 volts when rev'ed. We replaced the 2 wire voltage regulator with 2 other used 6 volt regulators with the same results. You can guess what is does to the rare 6v head light bulbs......I can not think all 3 6 volt regulators are bad but, then if they were good how could we have such high voltage at the H.L. socket ? So, I hook up an old 30 watt 12v bulb and it was real bright for like 30 seconds then poof.... I noticed if you wiggle the ignition/head light switch the head light changes brightness.... certainly, this couldn't be the cause of the high voltage ? Maybe it is as simply as using a 12 volt regulator and head light bulb ? Is the 6 volt battery simply for the ignition system ? Any one know where I could find a wiring diagram ? Thanks for any help !
