Battery eating bike

Postby cruelpaul » Sat Oct 31, 2015 7:41 pm

Hi, Newbie here so go easy please...
I just purchased my fathers 87 interstate with 55k on it, he had owned it for several years with no known issues. My dilemma is it seems to eat batteries, the last one lasted 30 miles, I did have to rewire the connector at the battery to make it home once and I thought the issue was fixed as before I did that the clock would constantly be resetting itself. Yet again today, last ride of the year it dies on me, jump start it, it stays running, lights are bright, but battery is fried.

Help please.

Thank you, Paul

If it's cooking batteries like that, I suspect it may be overcharging with too high a voltage. Put a voltmeter on the battery terminals and run the bike at around 4,500 RPM to see what voltage readings you get.

Are you buying a battery specified by the battery manufacturer for that bike? If so, are you charging the battery, they call it initializing, to its fullest before installation? New batteries come with directions on how to properly prepare them for installation.

Once installed and all cables are properly checked and hooked not only at the battery but at the end of each, then it is time to check that charging system as Wing Admin notes. It certainly sounds like something is wrong with your charging system and probably not the battery.

If you don't have a voltmeter, check at you auto parts store for one or at a Radio Shack. There are small, relatively cheap multimeters available that will be accurate enough for these checks.

You might want to take that old battery to a auto parts store and have it load tested to insure it is bad.

Wife's V-STAR did that, but battery was boiled dry and warped, bad regulator. Over charging seems to be worse for them them than under charging.
