Ok the battery test at 9.3 volts when the bike is running. I guess this means that the rectifier/regulator is not working? Any suggestions on getting a new one? |

I guess I am wondering if any 6v 4 wire rectifier will work. WHy did they have to make this motorcycles on a 6v system. |

Before anyone can even get a chance to anewer your question we need to know what year and model the bike is. My 1975 Honda mt250 does not have a regulator but uses a resistor hidden behind the headlight bucket. If that has failed or is not there or has a poor connection to it your headlight will burn out immediately when you rev the engine. Rick |

It is a 1974 mt 250. It has a big green resistor attached to the light bulb with a white wire. I guess I could try to check resistor. Any chance you know how to test the resistor? |
