HI everyone!

I'm a long time 2-wheeler rider but first-time scooter owner.  Just picked up a 2013 Kymco Agility 125 for cheap.  It was cheap because it comes with some electrical gremlins.

So here's the breakdown.

When I first bought it, the headlight and brake light wasn't working.  Only the front left turn signal worked but it just stayed solid whenever the signal was used.

I took it home, ripped it apart and found out that all the bulbs were blown out.  I ordered new bulbs, a new rectifier and a signal relay.

I put them all in and I get a dim headlight but a normal looking flash-to-pass beam ( voltage measured about 2V and 10V, respectively, at the bulb ).  No turn signals work.  Brake light now works but parking lights are still not working so no riding at night.

I should also add that originally, the fuses in the floorboard were exposed with no protection.  I snipped em off and replaced em with proper in-line holders and the accompanying 7A fuses.  Also, on that note, if I disconnect the red wire fuse, the headlight brightens up on low beam. 

I've tested all the grounds for continuity including the ones behind the front plastics and under the seat.  I'm not super electrically inclined, however so I need your guys' help on this, please! Otherwise this thing's going to be a daytime only scooter, which sucks, because it's 100F+ in the daytime right now.

Thanks in advance!

14 volts on a multimeter means next to nothing on a valid battery test. A load test is meaningful because you could have a cell that won't work under load.

I agree with Oldguy,about the battery taking a surface charge, but you did not say how old the battery is, or if you have any other devices drawing voltage from the battery. Also, Ive seen low milage on a machine but time killed the battery from sulfation-not enough use/charges. Here is a test to check how good the battery is.If you charge the battery fully, put it in the scooter and hook it up. Then hook up a voltage meter to the terminals. (See the chart below) While starting (or attempting to start)the scooter watch the voltage. If the voltage drops to less than 10 volts while the starter is turning the engine over, the battery is bad and needs to be replaced.(probably has a bad cell from sulfation) Each cell represents 2+volts. That is why you see 6 fill caps on a battery.  A new charged maintenance free battery should show about 12.9-13.0 volts. Here is a chart for maintenance free battery voltage, percentage of charge
12.9-13.0 volt    100% charge
12.6-12.8 volt      75% charge
12.3-12.5 volt      50% charge 
12.0-12.2 volt      25% charge
11.9 or less           0% charge
Kind of decieving looking isn't it. but this is out of the book information.  A Regular (non-maintenance free battery ) usually runs about .3 to .4 of a volt less on the chart. Now you say- what about that draw down when starting?, pulling the battery down to around 10 volts? well it takes alot of amps to crank over that engine-especially cold, so the voltage drop is normal, but a good battery will usually not drop below 10.5 volts while cranking the engine over. This is why the electronic stuff( CPU, electronic fuel injection,etc) operates on 9 volts, so every thing will work like it is supposed to while starting. Hope this information helps in the future.           This information applies to cars, motorcycles, and the like that is equipped with a 12 volt battery
