2003 Mitsubishi Lancer Evolution 4 cyl All Wheel Drive Manual
I would like to know what is the purpose of the G and FR terminals at the Mitsubishi Lancer EVO VII alternator.
There is B+ (output), S (battery sensor), L (lamp) FR (field report) and G (unknown).
I look at the wiring diagrams and both FR and G terminals connect to the connector C122 at the ECU. The FR is connected at the pin# 41 and the G is connected to pin# 33.
It seems that the FR is a report to the ECU if the field excitation is correct.
The " G" seems to be some sort of grounding control by a transistor. I would like to know what is the pattern of this control so I will be able to reproduce it.
IÃ‚ ´m installing a Vi-PEC V88 stand alone engine management system and I could not make the alternator to work. ThatÃ‚ ´s the first time I see this " G" terminal.
Thanks in advance!
