Looks like I may have lost ANOTHER Vp-44.... looking for options and ideas

Yeah it just too far up. Like I said normal should be 0.01 to 0.02. You really close to getting the 0.10 mark time for a change of alternator...

Thanks and guess its time to O/H the alternator then!

Getting marginal.

I wish there was a diode kit for our alternators. It would be nice to just purchase the diode pack and replace it. Normal good diode should be 0.01 to 0.02. Your 0.08 is very concerning.

There you go http://store.alternatorparts.com/ibr256---bridge-rectifier.aspx

Check your amps on back of alternator, this place has both.

Also my brushes were wore 3/4 or better got them from cluod gear with bearings, for $35 shipped. One bearing was stamped AVF and the other just numbers, B17-99D was big one with AVF on inner race, and 6003RD for smaller one.

DF,

 

Can you get to the diode's and brushes without taking the alternator off of the truck or is it better to remove the puppy?

 

Thanks for the link BTW!

You probably could change the rectifier pack by leaving it on the truck, but I would think that it would by sorta tough to do......... I would pull it.

Take the alternator out will make it a lot easier, and make sure you do change both diodes and brushes as old wore out brushes can make some ac noise, make sure you don't cut stator wires but rather old diode ones and then pry them apart, otherwise won't be long enough to crimp and solder new racktifire on.

Does your v/ac rise at all from .02 when you rev it up? After I rebuilt my alternator truck seems to run more crisp and haven't surged yet. I went back to local guy and he hooked his devise up to test diodes and it was mostly on good but not at 100% he said it was way acceptable, and other things could affect it. And with my fluke I get .03 at idle and .06 at 2500rpm. Just curios if you tried revving motor up to see any change.
