    This last order I made I got two magnets stuck together. My whole garage fridge is riddled with the rock auto disease.Poland? That’s dedication my friend; you’re a real one for that! I’m sure parts availability is difficult in those parts.

    Please stop posting all your google and AI results. Your posts are extremely difficult to read. Ask your question and we will answer. Before I even did any research I would've tested battery, cleaned and checked grounds, checked ALT fuse and THEN...

    It never hurts to get the alternator tested. For piece of mind. *I* believe your alternator is ok but you have voltage drop somewhere. I'd start by making sure your grounds are tight, clean, and secure. Battery to starter bolt and firewall are...

    Yes that's correct. You can google why there are two different settings and what it does.

    The alternator has two “modes” - low voltage/low load and high voltage/high load. The ECU controls which mode the alternator should be in using the “Generator G” pin on the ECU harness (pin 33). When G is grounded, the alternator is put into...

    The DC voltage settings are on the other side of the meter. You're on batt test. Go select DC 20 volts

    Guys I also wanted to mention I used to have a 98 GST with this same code - P0300. It had a 1g CAS for some reason. It had no balance shaft I'm guess it went went out and took out the crank sensor they switched it or it had a 1g head I’m not sure...

    Do you happen to use a 1g CAS? If so, have you confirmed that the base ignition timing is set properly? Maybe it's too advanced? And if the idle RPM doesn't lower below a certain RPM by bottoming out the BISS, I would also suspect that the...

    I believe it's FWD, automatic and overpriced.Also seems to have the incorrect spoiler on it but I may wrong about that. Looks like the 1Ga Eclipse spoiler and I don't recall ever seeing that style on a Laser.

    I feel like the alternator is going out do you guys approve of me taking the alternator out to bench test it or should I do some pinpoint test first thank you.

    99Dsmer was saying to check the g control circuit first this is what I found online.It is best to check the alternator B+ circuit first. The B+ wire carries the actual charging current to the battery. If this heavy-gauge wire is loose...
