problems with underdrive pullys
is anyone else going through alternators with underdrive pullys? i'm on my third in 8 months. i do drive the car everyday but i dont have a stereo or anything extra. could the pully be making the alternator work too hard?

That said, I'm still on my original alternator and have been running underdrive pulleys for years.

What winds up being wrong with the alternators? Bearings? Could you be consistently over-tightening the belt? Bushings? If you're buying rebuilt units some of the aftermarket bushings are really crappy.. Charging capabilities/Regulator? A bad battery or bad ground can really make the alternator work overtime..

Yep, I agree with NewbernD, overtightning the belt will cause the alt. to break, and also it will cause you water pump to break and leak which can result in overheating your motor.

oh, sorry i did but it was somewhere else that i posted it, the volts on the FC commander are spiking up to 15.9v but only when its in gear, if im in neutral and i rev it up it wont do it. it seems to go with the car when it jerks, like when i take off in first or am shifting gears and also sometimes when i'm on and off the gas, so pretty much whenever the car has a jerky movement. sometimes my radio cuts out, i think from the spike and all my light get really bright off and on with the spiking. hope this helps

Could be a ground problem. Check to make sure you reinstalled any grounding cables you may have taken off when you removed the alternator. Beyond that, I would suspect the battery. An intermittant connection -inside- the battery will do what you are describing. The battery post can come loose inside where it's staked through the buss bars that hold the plates.
When this is a problem, the battery appears good when tested. Try applying some rotation force on each post (with the cables connected). It's usually loose enough you can move it a bit by hand, and if it's still good you are unlikely to damage it if applying the force by hand. If you turn on the car radio and have it blaring, this battery problem will show up when you do this.

if you take out your batter it'll go much higher and fry **** (I blasted an injector).
