    AGM Battery

    The battery on my 88 is weak so I ordered an AGM battery (Absorbed Glass Mat). Has anybody tried one on their bike? I was searching for an alternative to the typical wet acid type batteries that I find myself buying every 3 years or so. The technology has been around since the 80's mostly in...

    Draining battery problem

    Hello all, I am having an issue where something seems to be killing my battery while my 85 vmax is off. It also seems to not be charging while running. My initial guess is the R/R for the charging issue. Haven't had time to go through the test chart and verify it. But just looking to see if...

    battery charging

    Hello all. Chuck here. I was wondering if anyone here had ever measured the amperage of the 3 wires coming from the stator. My bike is a 1989. I just replaced the r/r. I clamped an amprobe around each wire I got a reading of 17 amps at idle. Thanks----:bang head:

    New battery or not

    Had the non-starting issue after a quick run to Walmart. I've already got the replacement battery & R1 regulator/rectifier is on the way for upgrading from the stock r/r. Assuming the r/r is the reason why it wouldn't start, should I wait to install the new battery until after replacing with...

    Battery draining right before my eyes

    Hi guys, have any of you ever seen a battery drain as soon as you take the tender off of it? The reason I ask is that I am having some sort of issue going on where I HAVE to leave the bike on a battery tender. Today I pulled the tender off and measured volts at 14.3 after it sat for a few...

    New Battery? No spark?

    My bike died on me last month and the battery was flat and wouldn't charge. Prior to this it had been running fine. I replaced the Yuasa 12v 16amp battery with BS 12V 18amp, which was of the same dimensions and a perfect fit. Since fitting the new battery I have had a 'no spark' issue and the...

    Battery? Won't run?

    I was riding home last night and about 1 mile from my house, the bike just died. When I attempted to restart it but the battery was flat. I know there is no problem with the charging system, as I have a voltmeter on the bike, which showed it was putting out at least 13+ V when running. I called...

    Which battery charger?

    Evening all! I am going to invest in a new battery charger for 'Brutus'. But i am dithering between an optimate 4 or Ctek msx 5.0. Both have the facility of leaving the terminal cable attached to the batteries and both have appear to have trickle charge... So the question is, do you...

    Battery weak when hot?

    I remember having seen this on the forum somewhere, but my searches are not pulling up anything useful. My bike acts like the battery is low, when it's hot. Simple as that. When it's cold, it starts like a champ (with a little choke) and runs like a top. When it's hot, it acts like the...
