Killin' Batteries!
« on: October 17, 2009, 08:34:36 PM »
I bought a used 2008 Agility 50 (800 Miles or Km not sure) as an alternative to buying another car.  The battery died within the first few days of purchasing it.  The last owner assured me it was a fairly new battery but made good and bought me a new one.  Two weeks later that completely died.  I figured it as because I left the kill switch on a few times.  Last night while riding, I went to use the turn signal and i felt the power drop off and the turn signal did not engage.  I tried it again and the whole bike died.  The kickstart would not work.  My fiance met up with me to give me a jump start and had to give me three more jumps on our 4 mile journey home!

WHATS THE DEAL?!  Is this a problem with the stator not keeping the battery charged?  I've never owed a moped before o I have no clue what I'm doing. 

Please Help!

Im no expert but I would look for a wire with damaged insulation or a pinched wire or a sharp edge of some kind causing a sporatic dead short . Good luck .

The kill switch can not draw down power, so you can cross that off. Sounds as if there is a short as suggested above. You will need a multi meter w/ a 10 amp test mode. The battery can be charged overnight w/ an old camera wall adaptor, or a lap top adaptor, ect. as long as it has 12v output. Just cut the plug, splice the wires to a pair of aligator clips, and you have a "poor man's trickle charger. You can then hook the ammeter in series off the batt. to the positive cable to see if you do indeed have a current draw. (should be 0amp) unless there is a digital clock on your console then you will see around 5 milliamps. If all is good there check the batt. voltage w/ the bike turned off. (should be 12-12.8v) Start the scoot, and you should see 13-14.5v. If not you have a faulty stator or volt. regulator. If yours is a 4 stroke, the cdi is a dc fired unit and will not run. Check these out, and look for the service manual on line,(there may be a link to one on this forum somewhere, try the search feature). the manual will have some basic resistance values to compare for the suspect parts. Please post back so we can follow. It may just be a disconnected plug somewhere, but you will not know until you get into it further.

It was a bad regulator.  Being completely new to the wold of mopeds, I decided to take it to the local moped mechanic.  They took a battery reading. 12.8 with the moped off.....then when he tuned the moped on, it actually dropped to about 12.3.  He replaced the regulator and that was it.  I was kind of bummed to pay $65 for the part and the diagnostics when I could have just  bought a new regulator for $30 and popped it on myself. However, considering I would have had no clue if what I was doing was right, I guess the extra $$ was worth the piece of mind.

$65.00 Sounds "fair". Most areas are at least that for the labor alone. Glad to hear your running though, and thanks for the results! Happy scooti'n!!!
