Hello mates.
Today i check my alternator charging and for my surprise see only 13V on idle rpm. That 13V was measured with maximum load on the charging system. I mean i switch on the head light ,air con ,heating for rear window ,sound system and more. Before the winter start i check the systems and everything was fine (on the same load between 14v and 14.3v). So i gees there is something wrong. All off the measurements was made directly on the back side off the alternator to eliminate any bad ground spots etc. There is no difference wen i measured on the battery. The multimeter says exactly the same volts like on the back off the alternator.
On the back off the alternator i see two numbers 037 903 025 F - 0 124 325 011 90A
Can some one help me to find replacement parts number for servicing my alternator. I thing i need a new pulley and new voltage regulator.
Any help will be appreciated.
