What kind of wire goes to the PCM?
What kind of wire goes to the PCM?
The dodge wiring schematic showed a different color wire going to the PCM, one is for communication link red/white, and the other is for the transmission, pink wire. Please let me know what I am missing because your explanation of alternator/generator wiring is excellent easy to follow and not a lot of mathematical lingo.
What kind of voltage does an alternator have?
– The dark blue wire is the voltage supply to the Generator fields. Meaning this is a positive wire and should have 12V on a meter or light a test light like this when the test light is hooked to battery negative as in the picture.
Where is the PCM located on a Dodge alternator?
This is where the PCM lives behind your air filter box, notice I removed mine for better access, TURN THE KEY OFF before disconnecting. The connector closest to the passenger side is the Grey C3 connector. The Connector in the middle is the White C2 connector. Reference the wiring diagram at the PCM.
Where is the green wire on an alternator?
Connect one to a paint-free point on the engine, and the other one to the green wire. Actually, you can use either small terminal on the back of the alternator. The resistance between those two terminals is only four ohms, but be aware, it is common for them to read open circuit when the rotor is not spinning.
What to do if ECM is not communicating with alternator?
Put circuit tester between bat and cable. Tested all fuses by removal. Light on circuit tester still on. Removed hot cable to alternator, tester light still on. Any help would be great. I will reserve my diagnosis until comments provide diag/options.
Is there a bad wire to the ECM?
Suspected bad wire to ECM or ECM. The ECM in some manner controls the voltage regulator, which charges the battery. The voltage regulator works all on its own. The computer does not control it in any way. Yes the charging system goes through the pcm ,The Electronic Voltage…
What should the voltage be on an alternator?
Alternator Testing: What Is The Correct Voltage? For some alternators, it’s normal to see as low as 13 volts. For some, a constant 13.6 volts is an indication of a problem.
