ATV isn't charging, replacing voltage regulator didnt helped

[DracieVajko]

Hello, I cant find any solution... The problem is that battery isnt charging.. I located and meassured alternator cable, there was like 100-150Volts in cable that is going to the voltage regulator, but the output from the regulator that is going to the battery, I guess, was without any power, just 0 volts.. So I replaced voltage regulator but didnt helped. On fresh charged battery on turned atv is there around 13.5 volts, when I push gas the volts goes up to 13.6 maximum but the battery still isnt charging, by time it just drops down to 12volts and less again. I have no idea what is the problem here. I would appreciate every help. And sorry for my bad languagge :).

Assuming the replacement regulator is working (not Chinese junk that may or may not work), then it's pretty odd to be at 0V.  What are you using as a ground to check voltage?  at the battery?  Check the ground wire from the battery, if it's not grounded properly you won't get any voltage.  Or are you checking directly off of the regulator?

MAKE SURE TO REPLACE STATOR RECTIFER AND PICKUP COIL ALSO MAKE SURE THEY ARE PRODUCING VOLATGE WHEN MOTOR IS TURNING CHECK WITH MULTI METER ALSO CHECK ALL FUSES N ETC NEEDED TO HELP

Regulator is original replacement not Chinese. Last time Ive checked directly off the regulator so I will try ground from the battery.

Ive checked the wire from alternator and there is from 100 to 150volts so I guess this is good. And where can I find fuses (I have Linhai 500 if it helps) ? Like I have some case behind the battery that looks like there are the fuses but I have no idea how to check if they are good or not.
