    Help Sought w/ Charging Light on Cold Engine (m)

    For the 3 driving days I've gotten the "battery not charging" light (red outline of a battery) for the first mile ot two of driving. I had the system checked and my mechanic tightened down the cables etc. and said it was OK. This morning I got the light again, only I noticed that when I lifted off the throttle to shift to 3rd and 4th, and also when I just coasted, the light would go out. As soon as I hit the throttle again, the light came back on, but within another half mile, the light went out and stayed out.

    This makes me think that something in the charging and/or sensing system was both affected by throttle/power/torque and also not making contact until it warmed up and expanded.

    Anybody have this problem or recognize it? What's going on? Also, I had my mechanic change the belts at the same time as he was checking out the charging system. I had the same problem with the old belts and the new belts, so they shouldn't be a factor.

    Thanks,

    John

    Hmm. Kinda thinking brushes.

    But, then I've not had mine apart to see if it's even got 'em (I *think* they're part of the regulator module, as it is with the e30).

    If brushes/contact area has any excess corrosion/grease/etc., higher speeds would tend to "float" the contacts off the copper, especially when cold.
    Just my 2c.

    Object Lesson Herein (m)

    Turned out that the alternator was going bad and although I had the local grease monkeys check it out, they found nothing. So, I picked up the car and 1 miles later the battery light cam on and stayed on. The next day I was driving to the garage and one by one the A/C went out, followed by the seatbelt light coming on and finally kaput. Had the car towed and they replaced the alternator after calling and telling me it needed a new one for $750. My mind was on other things and I told them to go ahead. Picked up the car and the same eaxct bullshiat happened! Kaput and another tow. The head monkey then told me the rebuilt OEM alternators had a high instant failure rate..

    I said REBUILT for $750?? Long story short I bought a NEW alternator for $310 online, got a core rebate of $20 and will never go that Gas station again! Weird, the local garage is the highest local supporter of every civic venture and cause and uses that to rip the shiat out of their customers. What a shame!

    The "rebuilt" ones are nicely painted. And that's about it.. the garage was really ripping you off - the rebuilt ones cost about $135 or so. You can find new on line WAY cheaper then what they were ripping you off for.

    Did they kiss you as they presented the bill?
