  • Just picked up my new cruiser. It's cursed!

    My names Rene, just picked up my 2003 Silverado. Nothing was supposed to be wrong with it, but the adventure begins! Actually kind of looking forward to working on the bike since I have never worked on a motorcycle before. The battery is getting no charge but the bike runs great when jumped. New battery will start the bike maybe 4-6 times before it dies and back to square one. I'm already starting to trouble shoot the problem but find it hard to believe its the stator since the bike runs great once running so decided to buy a new Regulator/Rectifier. Hope that's the problem, I'm dying to put some miles on it. This will be my first cruiser, always had sport bikes. Looks like a great site and looking forward to contributing to the community.

    Welcome to the forum!

    Roadstars are great bikes and if you need help with one you came to the right place.

    Good luck with the new bike!

      Got to be a little more methodical. First off. Get a volt meter so you can check the voltage at the battery with the bike running. If the meter can check resistance, IE, ohms you’ll need to check the windings in the stator at the plug.

      There are other ways to deal with this problem than throwing money at it.

      Oh, and your bike has one carburetor. The fuel injected models didn’t appear until 2008.

        I have an 04 that I bought a year ago. The first thing I had to do was replace the alternator.

        With a bike that old, it is very unlikely that there is "nothing" that needs doing. In all likelihood, there are a number of things that need doing. Fortunately, this forum is just the place to come for assistance.

        There isn't a ton to the charging system of a motorcycle. Battery, regulator\rectifier, stator (alternator), wires, and fuses. My guess is the stator. Most folks suggest replacing the stator and rectifier together. The rectifier takes all of 2 minutes to swap out. Wouldn't it be lovely it this were the issue? Wishful thinking. As Bikerron said, a volt meter (micrometer) should help you find your problem.

        Here's the article that I found helpful in identifying and replacing a faulty stator.

        Happy gasket scraping.

        You probably also want to check your brake pads, tires, rotors, fresh brake fluid, oil change, gear oil change, new plugs, lube cables. You might also think about cleaning the carb and getting a fresh air filter\clean the old one.

        How many miles on your bike?

          from Sturgis Mi. My stator went bad last fall and it still ran great when I charged the battery. I suck at diagnosing electrical issues but the article from the old forum helped a ton and made it easy. If it is your stator be sure to get ome from an 05 because the upgraded them that year. Good luck.

            I was under the impression that when switching to the upgraded stator it requires the newer rectifier also. Is this true?

            I had my Stator Rewound to '05 Specs. and still run the '01 Reg./Rec. all is well. This is on my '01 Midnight.

            I’m impressed, as a stator pumping out more than the bike needs to run the electrics and charge the battery is just turning the regulator into a big heat sink when shunting the excess to ground.
            You must be running accessories such as passing lights, amp, etc., to keep the overflow at bay.

            Charging problems can be a pain to diagnose.

            Good luck and ride safe.

                thanks buddy. I saw all the recommended links for troubleshooting, good stuff. I’m looking forward to the weekend to go through the electrical system. I do have a meter, when I checked the battery off and running there was no difference so inspected the regulator. After checking the regulator with my meter it failed the test so decided to stop and purchase the new one. After reading the tech links I realize I should have started with the stator. I’ll check it out this weekend.

                As far as my profile regarding the Carb/Fuel injected its the only option in the drop down menu that would not redirect the page. It’s a website glitch. If you click “Carburator” from the drop down menu it automatically sends you to a sponsored link. Thanks for catching that and bringing it up though.

                I’ll post up how the stator checks out.

                  If you have to buy a stator buy 1 for a 05 -07 1700. It has a better charging capability. I also hope you ordered a reg/rec for a 05-07 1700. They are a direct swap and charge more amps.

                        OK. I think I've solved all my charging/starting issues. I reread the service log on my 2004 Roadie and it says it was upgraded to the 2005 stator/rectifier at 69K miles. The previous owner stated it was charging at 17.5 volts afterwards. Put the '05 rectifier in, still stops charging at 14.11 V's. Which is fine by me. But what's the output supposed to be with no extra load on it (no stereo, no heated gloves, etc...). Thanks.

                          Charging anything 15v and over is overcharging I'm sure the previous owner was mistaken about the 17.5 volts unless he changed the reg/rec again. the 14.11 you are reading is just fine. In fact it can be considered within a perfect range.

                            Representing Scorpion Gulch, Arizona. Doing things in the correct order can save you lots of time and money. Don't buy a cheap Chinese regulator, they are known to fail. Best bet is to get the O.E.M from Yamaha. Also, it's a good idea to do just one repair at a time. Otherwise, you won't know which one actually fixed the problem.

                              Copy that on the one repair at a time thing. Another pro tip: Review service records from previous owners, if available, prior to chasing gremlin's. I'm sure I read that when I bought the bike, but my memory isn't what it used to be...
