lyleh Posted September 21 Share #1 Posted September 21 I have a 2001 Yamaha Venture Royal Star with 114,000 miles on it. Today the bike quit on me and I determined that the battery is not being charged as the battery voltage does not increase past the 12vdc while revving the engine. I disconnected the cable from the rectifier and tested the diodes on all 3 pins and they check out fine according to documentation I found on this site. I also checked the 3 stator pins in the rectifier cable with the engine running and at idle they are around 25vac and when revved up they go to over 100vac. I am looking for input as to: · Are there other tests I could run? · If it is the generator would only the stator need replacing? · Do I need special tools to replace the stator? · Could it be the rectifier? · Something else I have not thought of? Thanks for any assistance, Lyle Link to comment Share on other sites More sharing options...
etcswjoe Posted September 21 Share #2 Posted September 21 Sounds like the rectifier, however, make sure you have continuity to the battery and ground from the rectifier, also inspect the connectors really well. The R/R connector and the stator connector under the battery box are usually the weak points. Link to comment Share on other sites More sharing options...
lyleh Posted September 21 Author Share #3 Posted September 21 Hi Crazy Joe, I have a question on locating the R/R connector and stator connector. My documentation says to remove the left side cover and possibly the inner cover then find the 3 pin stator connector with 3 white wires. I must be looking in the wrong spot as the only 3 wire connector I see is for the speedo, and the wires are not white. I have inserted a speed adjustment device inline with the speedo connector. I have attached a picture of what I am looking at. Would you let me know if I am looking in the correct spot, or where I should be looking. I did measure 12 volts on the connector at the rectifier and the pins look good. I really appreciated the quick response to my original post, and "thanks for your service"!

etcswjoe Posted September 21 Share #4 Posted September 21 Thanks, I am going to say that your stator connector is the white one hiding behind your fuel pump with the yellow sleeve, I had to take out the battery box to get to mine however it's not required if you do some digging. Here is an article that may help. The Venturers - Yamaha Venture Technical Support Library Link to comment Share on other sites More sharing options...
lyleh Posted September 21 Author Share #5 Posted September 21 Thanks for the call Joe, I really enjoyed talking with you. I did as you said and removed the radiator overflow container and found the connector when I was looking from the right side of the bike, not the left! The connections all looked good. The venture article you linked me to had a nice picture of it. Actually I had been referring to that article before and missed the stator connector pic. I am going to order a rectifier.

Lyle Cool beans, was a pleasure talking to you as well, us Venture riders have to stick together. Link to comment Share on other sites More sharing options...
lyleh Posted September 30 Author Share #7 Posted September 30 I just received my new voltage regulator and the charging system is now working great! My thanks go out to Crazy Joe for his input and to this site for the great service it has supplied to my tech questions. Lyle 1 Link to comment Share on other sites More sharing options...
