    I’m trying to upload a video of it but for some reason the site won’t let me I’m not trying to ask people what it is I’m just wondering if it’s normal it is coming from the alternator or near the camshaft right above it it’s hard to describe kind of like a bad idle pull but much deeper

    Using periods at the end of sentences used to be normal.. sigh.. complaining about lack of punctuation makes me feel old
    :pout:

    Does the noise go away if you disconnect the field connector while the engine is running?

    The idler belt bearing next to the alternator is famous for howling, make sure to confirm the noise with a stethoscope before jumping the gun.

    Not at all. Sometimes a failing alternator will make a whining sound. Its the sound of the internal magnetism struggling to generate any power. Unplugging the field connector will verify if the alt is noisy or something else near it

    The irony they're speaking of is the missing period or punctuation in your statements after noticing it earlier in the thread.
