It's charging your battery. You just used it to start your car.

I'm a bit frustrated with the squeak (just really annoyed by it). I'd LOVE to get to the bottom of it and fix it once and for all. It's obviously a very common issue, as many of us with the Innovate kit seem to have it.

Oh, I just read this. No. That doesn't make sense.

edit: I mean I agree it's not likely to be the alternator.

If not the alternator, then rotate all the idler wheels by hand (belt removed - duh).

If there is anything but smooth, dead silence, the bearing on that wheel is blown.

QFT- I have been lurking on this blower but don't have one. Not an expert with it specifically. Is the gearbox any stiffer when it's cold?

Yea it doesn't make sense. If they get squeaking from spinning the alternator pulley, then surely it's something else faulty inside the alternator......not the pulley itself since that part doesn't have any bearings and doesn't spin freely on its own.

I am the one that said I had a squeak coming from he alternator. I didnt say particulary say it was the pulley, just it was coming from the actual alternator.

I wonder if it has anything to do with running the gates blue belt.

i had a squeek with the gates blue belt as well.. loud screech only at start up.. never tried the other belt though..

I'd be willing to bet the belt material is too stiff and doesn't hook up enough. That squeak is just the moment after using the starter when the alternator dumps all it can back into the battery.

I think a video of the squeak would help. These blowers make a squeaking type of noise just by themselves. If you're new to twin screw blowers it is easy to mistake it for an issue when there isn't one.

Blue or standard belt won't matter since the tensioner sets the tension.

Disagree in principle. That's just like saying different tire compounds don't matter since the car weighs the same.

The belts aren't supposed to slip like tires do, so it shouldn't matter

5 minutes of google reveals the Gates Blue is a stiffer belt designed for higher loads. It matters.

It's definitely not the blower. I've had a few supercharged vehicles before, and they never squeaked like this. It's a very noticeable squeak that goes away quickly, once I start driving. It's coming from the belt or a pulley.

I'll try to get a video of it, when I get home on Sunday.

I'm also quite certain it's not the blower that is squeaking. It sounds like it's coming from one of the pulleys....bit I just can't pinpoint which one is faulty.

By the way I'm using the Gates K061015 belt.

How much preload is there on the tensioner? If it's slack, will the next shorter step fit? K061010 is about a half inch shorter

edit: I may be incorrect about the tensioner position if it is of a constant torque type. The shorter belt may not help/matter.
