Alternator or rectifier? Or something else?
Good day,
I have a CPI GTR 50 water-cooled (2-stroke) from 2004 and registered in 2006.
Unfortunately, the battery discharges while riding, and the scooter shuts off. I just removed the battery and connected it to the charger. Since the battery is only a month old, I don't think that's the problem.
Does anyone know what could be causing this?
Is it the alternator?
Do I even have one?
Do I have a rectifier?
If it isn't one of these, what else could it be?
I am grateful for any help!!
Greetings Luca

Yes, this scooter should normally have its own power path for the battery circuit incl. Blinker, brake light, E-Starter and possibly still have the instrument panel.
In contrast to the main lighting, this current path normally operates with DC voltage and should at average engine speed at the battery terminals be at about 13.8 to max. 14.4 volt charging voltage can be measured directly at the battery terminals.
Therefore yes, this scooter has a rectifier, as usually also a battery charger for the battery circuit either as a single device unit, or two-parts as rectifier + voltage / or respectively. Charger.
Unfortunately, I don’t have a multi/volt meter. However, have a digital voltage display on the charger. Up to what voltage should I charge the battery?
See my last comment in the thread of @JochenOWL
Please leave (light) gas for 30 to 60 minutes.
Without measuring, no one can tell you whether the problem is on the battery or on the lighting machine.
Please charge the battery fully.
Then disconnect the charger and measure whether the battery then has 12.8 volts, but at least 12.5 volts, which would be a little for a new battery.
If the battery has the voltage and also keeps – so does not discharge itself – then the light engine will be defective – photo below.
A new lighting machine costs only by 20€ and is installed quickly and easily.

In this trhread, I have to supplement you with your suggestion, because the scooter probably has a separate charger / rectification unit for the battery circuit:

That’s sweet of you, because you’re one who likes to help others.
My problem is that I’m here – in the voluntary rescue service – only have a small smartphone with me and don’t come to my documents that I have on my PC.
I know, however, that in the and similar scooters, the light engine will give up the mind.
But now the FS already has information.

I think I’ll find him under the front panel right?
Up to what voltage should I charge the battery?
Update. A connection of the + pole is slipped off. He’s probably responsible for the E-Starter. Now the scooter starts again. Get me a multimeter later. How can I check the charge/equipment?
It has 13 V
How much volt does the battery have now?
The charging current was at 1A and the voltage up to which I charged the battery was 14.1 V. Was the battery then still approx. Leave it for 2 hours until I reconnected it. When I joined them, only one more came when I activated the E-Starter.
Please ensure that the actually flowing peak charging current does not necessarily exceed about 1/3 to 1/2 of the battery nominal capacity in Ah, and that the battery is no longer handwarm.
The main headlight is normal with the motor-speed-dependent change in brightness, because it is generally not supported by the battery circuit in small motorcycles.
Which charger have you currently attached to your battery exactly at home, and at what voltage with which charging current is it currently working?
Up to approx. 14,1-14,2 volts to short “Sprudeling” for the purpose of mixing the acid You’re going to the warden tonight.
After that, turn off and clamp.
I can borrow this week. With the flashers, the brightness does not take so much. But headlights definitely.
The battery is still on the charger. Up to what voltage should I charge? Is ne 12 V 4 Ah if it is relevant.
This is no problem @JochenOWL. You are a thematically pleasant contemporary, with which I like to work together with each other for the good of requesting users.
@DerLuca61 ,
will your blinkers become a bit brighter when you bring the engine from stand gas to about 4000 tours during flashing?
Or do you have a multimeter to hand or can you get such a pardon?
