Why won't my scooter stay charged?

by Anonymous

I have a Baja 125cc scooter and the battery keeps dying every 5-6 days. Any idea why and what I can do about it?

Poor ground
by: Gary

Sounds like leak down caused by a poor ground. Check jumper from frame to engine is secure and directly against bare metal, not painted, surfaces. If surface is painted strip a spot and reconnect.

You can use silicon dielectric grease to stop micro-arcing and corrosion. If jumper is indirectly attached, such as over a metal bushing through a plastic cover, replace it between the plastic cover and the metal cover it attaches to.

Even if a test shows continuity, which it probably will, if the connection is not against bare metal, redo it. Thread flanks through attachment bolt alone do not always provide adequate ground, the connector end should be against bare metal.

If left untended, a poor ground can cause coil failure, in addition to battery leak down.

When you start the scooter, put a volt/ohmmeter across the battery set at Volts DC. It should read at least 13.5 volts. If not, your regulator is bad or a wire is bad and the system isn't charging.

You are not using the scooter enough. Remove the battery and connect it to battery tender.

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.

ATTENTION! I have had to delete the Scooter Forum for this site, unfortunately. Despite my best efforts, I could not adequately prevent daily attacks by hackers and spammers. Even though most of their posts did not go public, they still cluttered up my website host's server space, jeopardizing my account. I appreciate everyone's contributions over the past few years and I apologize for having to do this.

Wondering why your scooter question never got posted?

Chances are, there is a good reason. Did you...

If you "checked yes" on any of the points above, then I've deleted your post. Sorry, but I have standards. Feel free to re-submit, following the instructions I have everywhere on the site.

Also... all submissions have to be reviewed by me, and I am currently backlogged. Comments go live without approval, but still take 30 to 60 minutes to show up, so don't repost them, please.
