Mystery batteru drainage

Dabby40 · 12-29-2023, 11:35 PM

My Bashan storm has some battery drainage issue I cannot seem to find the reason for. A full charge of my battery takes maybe 5 days then it's dead again. Any parts/areas I need to look at?

Looked at:
Battery - Changed out roached battery when I bought it with a new one that still registers as it should.
Alarm system - Removed this as soon as I bought the bike as I read it drained batteries like butter. I will say there is a weird wire that looks similar to a wall plug on the bike after I removed the alarm system. Will show it in the morning but I never saw this on any other bike I have owned.
Starter relay - Tested and works as it should and cleaned it a bit since it was, like everything on my bike when I got it, covered in sand.

It is a pain in the neck dealing with slow voltage drain

First, disconnect the battery and charge it. Check the resting voltage with a voltmeter/multimeter...should be close to 13 volts. Then connect it and see if the voltage drops. That will verify that it is the bike, not the battery.

Then, methodically disconnect systems, like the lead to the starter relay, then the CDI unit, light switch (left side controls), ignition switch, starter button and hazard flasher (right controls switch), regulator/rectifier, etc... See if/when the voltage drop goes away. Hopefully, this will help you isolate the problem.

If that works, you can drill down on components if it isn't already obvious.

Found out what the issue was today! My starter relay died. Bike wasn't running and made the dreaded dead relay noise. I love when things sort themselves out.

Also here's that weird ass cord I mentioned I have no idea what it does.
