help me asap!!!!

my 50cc all of a sudden with a new sealed battery fitted keeps going flat its only just over a year old and I WOKE UP WENT TO START THE BIKE LIGHTS WORKED FINE THE NEXT DAY, ALL 4 HEADLIGHT BULBS ( 2 CAPLESS AND 2 HALOGEN ) WONT WORK ON NORMAL OR FULL BEAM

PLEASE HELP !

 

Check the basics:

Fuses, see if the connections are tight, no corroded terminals etc. if you a voltmeter check you ouputs from the stator windings

 

have you got horn and rear/stop lights

 

If you sure its the battery Id speak to manufacture as it maybe under guarantee

 

Grab a volt meter, any standard tester will do, start the bike, put the probes on the battery terminals, red to positive, black to negative, check the reading on the meter. With the bike running it should give a reading of 13.6 - 14 volts. A little higher is ok, but any reading above 15 volts means the voltage regulator is shot and is probably killing your bulbs. If the reading is 12.6 volts or less then the charging system is shot and you need to replace the stator and pick-up.

 

Theres a man who should be commenting

 

everything else works fine ? :L

 

could just have a bad earth somewhere..if you got back light and stop lights,ide say head light earth.

 

did the halogens ect get wired on a relay

 

also is your new battery up to feeding extra amperage or the charge circuit up to keeping them happy with a bit for the battery

 

i got a new upgraded battery like 2 months ago its like 7-9 amp ? over the standard one its a sealed lithium one ? i dunno why all of a sudden they arent working ?

 

you are using a battery that can supply over 100 watts of power over an hour.volts times amps= watts.your charge circuit has to recharge when its going along fully lite and under load.calculate how much wattage All your bulbs are and using total wattage divide it by 12 this gives you your TOTAL power need .if you then add a 20%on top to allow the charger to keep up...coil output ammerage should at least be that much or more.you wanna ride a Christmas tree..you may be needing a bigger charge system

 

could also have burned the crap out of the hi
,,lo switch.are they on a relay or wired to your standard lights via switch

 

the high low beam is seperate but it is wired to the same lights

 

if im getting it right,you got extra front lights wired into your front switch but on/off switched seperate.(have back light and stop) ide check for voltage before and after the switch and earths on the h/light bulb.if your running a 35watt bulb and have put another on making 70watt , it could be you've burned the hi.lo switch out.rear light is internally connected in the switch so its on all the time the main on/off is on.what needs to be done is wire the lights on a relay.this allows the voltage to be switched via your original light but have the supply voltage switch through a set of contacts via the battery. With bigger bulbs..more strain on the switch.
