Hey.
A while back my alternator started only charging a bit and eventually stopped charging after I reached higher RPM. In the meantime I also had something that looked like a short, because when I turned off the power to my gauges, they would still receive enough voltage to actually turn on and function. I settled with the thought of the alternator being broken so I bought a new one. The new one doesn't charge at all and I'm unsure if there is a short now. I'd like to get some tips, please. Also I wonder what specific voltages I would get from that 4-pin alternator plug? I get 12V on the red wire and I got something like 4V on another one and the two others were dead. Does anyone know what voltages to expect here? To be honest it also looked like it had a slight burn mark from the 12V pin to the pin next to it, but I'm not certain.
The battery is fully charged and I have tried with two different batteries. It had about 12.5V when I start the car and it falls to about 11.4V when running. I've tried increasing the throttle a bit also, but nothing happens. I'm doing the readings with a multimeter at the battery terminals. I've also checked for continuity between the battery and alternator and checked that it's grounded properly.
Thanks in advance..
