How do I fix scooter headlights that keep shorting out?

by Joe
(Baltimore, MD)

My 150 cc scooter headlights are shorting out, back lights work fine. How do I fix? It seemed to happen after someone rode it and hit the mirror into a fence. Sometimes the lights work and sometimes if I go over a bump they do not. How can I tell if it is a fuse or loose wire?

Okay the scooter does something different.

The High beam bulb only lasts a few seconds to a minute before going out after replacing.

The low beam headlight goes out after a good 10 mile ride in city.

Last time I replaced the lights, my dashboard lights went out, and one of the bulbs for the turn signal in the dashboard also went out. Both headlights went out, and tail light went out... ( All the lights are supposed to be on when the scooter is on.) However...

The tail light still turns on when I press the brake, and the turn signals also work Starts fine with a normal charge and fuel.

What do?/check?

Also on another note, the scooter is dragging up to speed. I have to rev it up again and again in fast succession to get it to go faster. (at least to bring it to 40 mph in city. that's as fast as it pushes for now.)
If I open the throttle all the way it stops speeding up after 25mph and seems to backfire, like sputtering .

I suspect I need a new spark plug/ or spark plug wire, since the fuel filter has already been replaced with a universal one of the same size.

Sounds like you have loose wiring go in and check the cables that are hooking into the lights make sure that they are fully plugged in. If that does not work make sure that none of the wires are damaged and that there are no breaks in the line. Also a issue that sometimes happens is that the wiring going to the lights the ground wire is loose or is broken off and then only when the wire touches metal does the lights turn on.

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.
