  • Dead Battery??

    Hey folks! I have something killing my battery....
    i went to fire up my 03 roadstar 1600 and the battery had like 9 volts. So off to parts store I went got a brand new battery road it home and went to ride today and boom dead again!!
    this time it was so dead the neutral light wouldn’t even hardly light up before fading out. I have no extra lighting or anything on it does anyone know what could be killing my battery?

    Was the new battery fully charged when installed? Don't try to start your bike with a low battery as it could fry the points on your starter relay next.

      low voltage means high amperage. ohm's law

      I think i've read on this forum that if you don't charge a new battery per the directions before use you can actually damage or shorten the life of the battery.

    Not sure, I assumed it was charged being new

      Never assume anything, Fully charge it and try again.

    I would put my amp meter in series with the batt. terminal to see the draw, set to dc milliamps. If i see a draw then I start taking apart all the connectors one at a time. Could be just a little corrosion on a connector. Process of elimination. What I don't know is what the clock may draw but once out of the system you should be able to find it.

      First thing. Need to charge it back up and put a volt meter across the posts of the battery and see if the bike is charging at a fast idle.

      13.8 - 14 volts is the norm.

        you would have to put a amp meter in series with negative cable and batt post to see amp output. Anything below 4 or 5 amps charge rate is low. and rectifier may be bad. To check stator you can run engine and check for voltage at the plug. It should read well above 60 70 volts at couple thousand rpm. that would be ac voltage.

      So, how many folks out there have an amp meter?

      A volt meter is all you need to diagnose a charging system. At the battery and stator plug.

        those are some shitty directions. How does that help the guy out? Maybe you could explain, I would like to know also.

      A voltmeter really is all it takes to diagnose the charging system on the Road Star. Besides an ohm meter that's all that is used in the service manual.

        What's a "manual"? A Mexican gardner?

            That’s good, but don’t assume a tender will charge it fully if it was low. Use a good standard charger initially, then a tender to top it off after each ride. Many tenders won’t charge once below a certain voltage.

              I never put a tender on mine and don't have a problem. I was told if the kickstand is on concrete can cause a little drain on the battery, I do keep my kickstand on a rubber mat when parked at home but ride almost everyday too

            Sounds like a myth to me!

              yep nothing but an old myth. storing batteries directly on concrete will not hurt them at all. My whole career as a mechanic our stock room stored batteries on the concrete floor and it never hurt even of them. MYTH,MYTH,MYTH

              could be, It doesn't sit to long anyway! I don't know where I heard it.
