Battery problem

[GasGasRider_]

Hi, i have a problem with my Gas Gas ec-e 300 2014.
My battery wouldn t charge, light and other equipment work normal but on full throttle it start to bug.
Every information is helpful.

How did you find out that the battery isn't charged? Did you measure what voltage you have at the battery terminals when the engine is running and revved?

 

[GasGasRider_]

It is 12,80v all time, when i open light it fall on 12,45v

So it's not charging.

,measure the AC voltage from the stator. Should be say 50v ac. Then into rectifier..

Stator has been removed , does the engine have to run for examine it

 

[Neil E.]

You can certainly inspect it out of the bike, but it's got be in place to check the voltage output with the engine running. With it removed you can do resistance checks to see if any windings are "open" (broken).

What wire i need connect on multimetar? I put stator in bike and connect yellow and brown wire on multimetar. Voltage is 26v.

Been too long since looking.

So what wire connects AC to the rectifier?. Is there any DC output from the output and ground?

 

[GasGasRider_]

Yellow and brown wire go to rectifier, white and second brown to cdi from pickup. And there is red and blue wire that go nowhere

 

[Neil E.]

You must have the estart model. It uses a DC powered CDI, so the "single winding" wires are not connected to anything. You should get a high AC voltage on the two wires going to the rectifier. If not the stator may be bad. Clean and grease every wiring connection. Clean every ground point then try running the bike and checking AC voltage out of the stator. If it's high (50-60 volts), then check the DC voltage out of the Reg/Rect. If low you need a new Reg/Rect. If your battery voltage drops low enough the CDI may start misfiring.

Download the 2014 GG enduro manual. It has wiring diagrams in it.

Thanks i will check this, but one question. I have stator like this on my bike https://www.motocrosscenter.com/sho...-300-2018-2019-5016-725-194-0-0058209101.html can i put different one on bike like this one https://www.enduropuro.it/shop/en/electrical-parts/850-stator-gasgas-ec-200-250-300-00-13.html

The units on those listings appear different, but someone else may be able to advise you. I don't know what differences exist on the newer machines. If you search a bit you can find topics here that show how to install a common KTM stator on the GG mounting plate. A little modification to the wiring connectors is required. Here is a photo of the 2011 stator. Note the number of windings.

I was check possible solution. AC voltage from stator is 50-60V on normal throttle but on full throttle is 80/90V. Is this ok or to high

 

[Neil E.]

Don't get too concerned about the actual AC voltage. You are measuring it with only the tiny load of a multimeter. Under normal conditions the regulator/rectifier will clip the excess voltage. The actual DC voltage output should be anywhere from 13.8 to 14.8 volts. Try a new R/R and measure the DC output.

Hi guys, i solve my problem, the problem was reg/rec.
Thanks everyone for help.

Sweet. Glad you got it sorted.
