Despite my little erm...'oversight' yesterday, ahem
This time I really DO have an issue:
Brand new battery yesterday, started no problem, rode around for a few hours, each time starting of the remote or electric because the Kick-start is Donald.
This afternoon, batterry is dead! No headlights, indicators very weak. Starter motor just clicks. But alarm on/off works and sounds as loud as ever.
So what had drained a brand new battery over night? Scoot was locked up and garaged overnight so I didn't even have the alarm on - could it still be draining the battery if its not on?
Makes we wonder if what ever is wrong was what fryed the original battery - basically I never to got to use the electric start because apart from the odd occasion there wasn't enough charge. Lights etc were fine but not the starter. This is what lead to me over using the kick until it slipped and sheared all the teeth smooth.
As always, any suggestions gratefully received

My guess is either a short (battery draining to earth) or a dodgy voltage regulator (too much charge going into battery at high revs). You need to get a meter and test the voltage going into the battery. It shouldnt exceed aroung 13 volts.

OK, Cheers
Just one thing......if I get volt meter, just what do I do with it?

How about if, for the time being, I get the battery charged and then just connected beofre I ride the scoot and then unhook the connections after I've parked up?

You will probably find that although you bought a new battery, sometimes they are not fully charged when you buy them. Whilst you may of had sufficient power in your battery to start it, it was ok while the engine was running but was not running long enough to replace the current you used in starting your bike initially.
Therefore, remove the + battery connection, connect up your charger charge you battery overnight and your problem should be solved. If not then you have a short somewhere and you will have to find it and isolate it. You could of course have a look at the wiring looking for any signs of scuffing on the wires. It does not take much to wear through the insulation on thin wires that are used on scoots. the cure insulating tape and plenty of it should you find anything suspiscios.
If your wondering why I say disconnect the + lead from your battery its to prevent diodes blowing in your rectifier. This can and does happen with cars too so a little prevention initially saves a costly repair later.

Sorry to hear your having problems hodgeyboy. Can't help coz my technical and mechanical knowledge is the laugh of the campo. Could it be even that you've bought a duff battery, after all you are in Spain. Good luck, hope you get it sorted.

i was having exsact same probleem it is the immobiliser that drains the battery best thing to do is charge battery fully and go for a good long ride
also when you get the multi metre put the one prob on nag terminal and other on positive this will give you the reading of volts in the battery if they go down somthing is draining it
next start the bike and repeat process this will tell you if battery is charging properly

OK, I've got the Multimetre and the Battery Charger - which is a story all of it's own.
Now, assuming I've not (continued) to be a total thicko, I think I've got it right so far...
Set the meter to 20V on the dial and used the probes to, er probe (Oo-er) the battery which gave a reading of 07.5 ish so that means that it is v. discharged, right?
Got the battery hooked up to the charger and as the charge increases closer to 100%, the ampmeter reading on the front of the charger will gradually decrease - correct?

depends on if your battery is 6v or 12 v if six volt 7.5 indicates your battery is ok as your charger nears completion of charge the amperage should drop to a trickle, ie the needle on meter decreases just as explained. If you had a 12 V system you might get a reading of 13.8 volts. Looks like you have a 6v battery. some people leave a battery on charge over night to ensure a full charge. Your battery when charged after you take it off charger should read a little in excess of 6 volts. Same with a 12 volt system. hope that helps

OK, so it is a 12v battery so 7ish would be a low reading and I'm looking for a reading of a little in excess of 12 v when it's ready to roll.
I only ask because the instructions on the charger and multimetre are all in Spanish (well of course they are, thats where you live!) I know sometimes you get the 'international' instructions along side,but not in this case.
There's only so much accuracy in translation sites like BabelFish!

Give it a good charge overnight, in the morning it should be ok but before you connect to bike check the voltage in the battery it should read a little in excess of 12v. With a fully charged battery you should be able to start you bike off starter then warm it up or take it for a spin. When you return check with meter, when you have the motor running the voltage should increase as the alternator is trying to replace the current that the bike is using. The same applies when you turn on your lights as you do so you might experience a drop in voltage this is normal.

SUCCESS - so far
Charged up the battery over a couple of hours. Amperage (hark at me, with the jargon!) went to zero, and checking the multimetre reading of 13.3V.
Stuck the battery in and it fired up so I'm off out for a ride for and hour - or three...
Question now is; ONE) IF my scoot is draining the battery how and where to I go about checking and TWO) I haven't much need right for the alarm right now and I reckon it's number one candidate for the battery drain - which wires do I nned to turn my attention to to disconnect it?
You know there is a chance, one day, just maybe, that I could actually answer some body elses questions....only they would probably have to be about something other than scoots!

Dunno re alarm. Just look at the wiring wherever you can see it,Has it rubbed and chafed? Can you see any damage or wires hanging free which look like they should be connected? Have a look inside the lights as well. Some bikes have a courtesy light under the seat. Does yours? Does it switch off when the seat closes? You know there is a chance, one day, just maybe, that I could actually answer some body elses questions....only they would probably have to be about something other than scoots! Give us a Paella recipe then!

after you have ben out on it stop and then do test on battery with multi metre as before if its still draining the voltage will go down
you may get a slight drain off alarm but not too quickly

All seems fine re: above two suggestions - thanks again.
Can't do much about the wires now as I'm on shift for 4 days from tomorrow which doesn't leave much time for anything else other than sleeping, scooting to work, talkin' to poker players on the phone for 12 hours then scootin' home and sleeping.
Just to be sure, I've disconnected the battery for tonight as I've absolutely GOT to use the scooter tomorrow. I'll investigate further in the coming week
cheers
