Dead Battery every two days

Postby Mad Meteor » Tue Mar 29, 2016 6:02 pm



How much current should I see across fuse #22 when the ignition key is off? I have a triked 2002 GL1800 with 86 thousand miles on it and the battery dies every two days unless ridden or plugged in. I have changed batteries and verified that the alternator is working (recently replaced it actually) but it will present with a dead battery if parked for two days. In checking with a cheap multi-meter I see .01 amps being drawn across fuse #22 when the ignition key is off. With fuse #22 pulled than I see no draw. I know there is a clock in the radio but don't know how much it should draw. Any thoughts?

Personally, I can't see how .01 amps would kill a battery that quickly.
I would suggest having the battery charged and getting it load tested.
There have been threads on another forum that hints at a MP3 player drawing a battery dead in a short time...do you have such a device, maybe hard wired to the battery where you wouldn't "see" the current flow through the fuse panel?

There is an MP3 player that is connected through the CD player input but it hasn't been used for a long time. I don't know why I didn't think of it before but having the battery load tested is an awfully good idea.

As stated earlier, your problem is elsewhere, you said you have replaced the battery and assuming you fully charged it before installing it, 10mA (0.01Amps) would need ~2000hrs (battery is a 20 Amp hour battery) to flatten the battery, that is 80+ days. If your battery is going flat in 2 days either the battery is defective, is not getting fully charged when you do ride it, or you have something else taking current that is not passing through fuse 22. You are looking for something that is taking ~0.5 amps to flatten a battery in 2 days.

Okay, it appears that the battery was the culprit. I thought I had switched batteries but it seams that I actually hadn't. I have three Gold Wings all with the same brand of battery and while playing musical batteries I ended up putting the suspected one back into the Trike. Its difficult to admit such a stoopid mistake but there it is. Thanks for the help.
