I New Alternator New Fusible link and I still have low voltage battery light in the dash that went away I have read a lot in I Can Find The problem HELP
You have 3 fusible links in this vehicle.
18 ga brown on right side of engine compartment
12 ga gray at rear of engine compartment
12 ga gray on right side of engine compartment
All three of these are involved in charging, so make sure all three are good. Resistance end-to-end on each should be zero.
You have two wires that go from the alternator to the PCM. One is light green + orange which should be at ground voltage and the other is light green + red. This one is a control voltage sent by the PCM to regulate the alternator charging voltage. Both of these wires must be connected on both ends and intact and reading correct voltage for your charging system to work properly.
I don't know the correct voltage range for this light green + red wire. For a step-by-step procedure to diagnose your charging system yourself, you can subscribe to a service such as AllDataDIY.com, which will cost much less than replacing parts that might or might not be bad.
