Scooter won't start after recharging battery

I went away for a month. When I returned, I turned the key and the lights and fuel needle came to life but no sooner I pressed the start button, the electrics went completely out without the engine turning over at all.

I took the battery out and charged it but after putting it back in, exactly the same thing happened.

This scooter has always been reliable where many times I have been away only for it to start up straight away.

HOWEVER, there is another piece of information that might change any diagnosis that someone might have at this stage:

Just before I went away for a month, I was approaching my destination and it completely cut out at the lights. Nothing would come on, the engine wouldn't turn over etc. I had to push it about 50 metres to reach the destination.

Would something like the regulator just all of a sudden die like that?

Thanks very much and hope you can help.

My scooter is a Honda @/NES 125cc.

 

Could be a few things. I guess it's possible the regulator could die all of a sudden. Has your bike got a kick start?

 

It doesn't unfortunately.
I have one of those power bank jump starters for my car.
Do you think I could use that?
Thanks.

 

I don't know because car batteries are bigger and it might damage your electrics. I'd hang on until one of the more knowledgeable members here come on line and gives you the right advice.

 

You could try your jump starter ok. It soulds like you might have a bad earth connection. But try the jump starter first. Battery size does not really matter, it is the voltage that counts, so as long as the bike is 12v all will be fine. Just remember to put positive to positive and earth to earth. I very much doubt it is the regulator. But try the jump start first. If no good check all the electrical conection, especilly around the starter solonoid.

 

I would be looking at your battery connections and possibly the main fuse.

 

I think I have to order a new battery BUT it seems the scooter killed the battery from what my limited knowledge ascertain:

• I successfully charged the battery according to the charger. The battery displayed 12.5v after disconnecting it from the charger.
  
• I put the battery in the scooter, turned it on, the fuel needle moved and service light came on as normal.
• After pressing the ignition, it made a short click and everything turned off such as the above.
• The battery now read about 1.8v!
• I jump started it and it worked.
• Whilst the engine was running, the battery now read about 3.2v

Would I be right in saying that the battery is buggered and it's not being fed enough volts?
I know that if it was being fed over 15v then that would apparently damage the battery but it's being under fed here.
It seems this does not narrow it down because I'm assuming it could the wiring, stator or regulator that's the problem.
Does that information help or do the previous suggestions still stand?

Thanks again.

 

Sounds like it's frazzled to me.
Still sounds like you are shorting out somewhere though. Sounds like the starter relay is working, and the 12v feed from the relay is going straight to the frame or something
