My check engine light comes on. I check the fault codes and 33 and 41 come up. Since I dont have a/c in my truck, that eliminates code 33. Code 41 says alternator field control circuit open or shorted.
i have traced my wires. I have a brand new alternator installed. My battery terminal was corroded so I replaced the battery cable connector. I cleaned my ground wire. I think I looked at all the wires. But my mechanical gage still shows that the battery is not being charged.
I have read the the power module and the logic module could be bad. I dont know what these are or where to look for them. Where can I go to find a picture of them? I also would like to know what you think could be the problem. Where is the voltage regulator circuit and how do I check that?
have the same problem?
