Well, I finally got to go for a decent ride to celebrate getting a new job (no more temp job crap!!!), so I rode 2 hours up to Frisco and back, and my headlights started dying out about 10 miles from home in the middle of I-25 in the pitch black. And it started dying like to the point that I couldn't keep up with the 80+mph traffic. Better yet, I was in the left lane because I HAD been passing everyone, so had to a 3 lane dash to the right shoulder with failing lights and lackluster acceleration. I shot across to the left shoulder with semis honking madly at me (yeah, I know what I'm doing, I know you're there, honking aint helping!!!!) I rode along the right shoulder, with a dim headlight, hitting all of the tread casings littering the shoulder, and finally limped home wiht a flickering speedo light and dim headlights and no turnsignals. TO me, that says the alternator is gone and I'm running on the battery, any ideas?

Have you checked the voltage ? I had the same, was the R/R crapping out.

I've been diagnosing my charging system myself. Not the same symptoms, but I've all but determined that my R/R has failed. You can narrow some things down pretty quickly with a multimeter. Lots of good how-to threads here and on youtube, etc.

Frisco, eh? Beautiful - I used to live there. Miss it!

Chy's faster than me. Sorry. If ya look in "Performance Mods" there is a thread called "regulator mod done" and it's got all you need to know about how to fix that.

Maine. Here are a couple of tutorial videos that may help. If you check the R/R be aware that the input wires are black with a blue line. I confused one for the Neg. output wire and my readings seemed off, but when I noticed the error and re-checked, they were fine.

OK, folks, here is another question, if I'm seeing 11.5-12V at idle from my battery I should not need to check each leg of my alternator stator for damage, right? I'm still planning on doing the mod, but am assuming that if I had leg to leg damage on the Stator, I would not be seeing normal charging voltage at idle.

11.5 to 12V is not normal charging voltage.

Ditto, should be 12.5 or better i should think at idle higher at 2500 and 3500 respectively.
