jsbsti Posted June 16, 2023 Report Share Posted June 16, 2023 Hello, I have the alternator voltage that drops, do you think that the alternator is tired or that it is the regulator that is too slow? On subaru ej 207. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 17, 2023 Report Share Posted June 17, 2023 Cant really tell from just the voltage, you really need to put an amp clamp on it to see if the alternator is outputting its rated current or not. jsbsti 1 Quote Link to comment Share on other sites More sharing options...
jsbsti Posted June 20, 2023 Author Report Share Posted June 20, 2023 Is it possible to control the alternator? @Adamw Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 21, 2023 Report Share Posted June 21, 2023 It is not an ecu controlled alternator in these. Quote Link to comment Share on other sites More sharing options...
kaptainballistik Posted June 21, 2023 Report Share Posted June 21, 2023 You Need to put an Oscilloscope on it whilst its under load, (all the lights, heater ect...) But that looks like a dud alt. Quote Link to comment Share on other sites More sharing options...
