I know this has been posted a bunch of times, but...
At idle the volts off the back of my 80 amp one wire alt are too low, around 11 with no lights or acc.
How do I fix this?? Getting tired of the stero cutting out when at idle with headlights on and i operate the power windows.

Who's 1 wire alternator are you using and can it be set up as a 3 wire? Not a lover of 1 wire set-ups.

go to www.madelectric.com and read up on one wire vs. three wire alternator, and read about remote voltage sensing. I suggest you convert to 3 wire alternator and sense your voltage with a 12 gauge wire at the your junction block where all your accessories,etc draw power from. It will explain this. Also upgrade your alternating charge wire to 8 guage if you haven't already. Much heavier than stock 10 gauge.

I run a Powermaster alternator.

Ran it in "one-wire" mode for about three years. Then switched it to "three-wire" with remote voltage sensing. The difference is like night and day. No more dimming lights or other evidence of voltage drops when I increase the load on the alternator.

Got it fixed! The issue was the alt pully. When going to the power saving system from march the crank pully was smaller but the alt ully stayed stock. I ordered up the small 1.5 in pully and now volts are staying at 14.
So nice to not have to jump the thing all the time!
