I've had concerns about my voltage regulator since I installed it maybe 100 or so hours ago.  I run an analog gauge so accurate read not really possible but it always kept the batteries charged with a low amp read.  I put in a small digital gauge recently and confirmed the low voltage read, at most about 13.2V in cruise.  I called B&C to confirm the exact tool I needed to adjust and they indicated a slotted screwdriver.  Trouble was the adjustment hole was sealed with some kind of crap I couldn't dig out, hot glue or something.  I decided to exit my recliner this afternoon and try it again.  I had probably spent 30 minutes in the past trying to dig the stuff out without success.  Today I removed the regulator from the firewall to rotate to a better work angle while not removing any wiring.  Success!  With a dental pick and 20 minutes of effort the adjusting screw revealed itself.  Book says 1.6 volts per turn so I cranked in 4 or so turns, not being very accurate, and did a quick engine run.  Wow, I went way too far. After the engine warmed up I took it to about 2000 rpm and I was getting 15+ volts and climbing.  Not wanting to remove the cowl again today, I'll adjust it down on next airport visit and run with top cowl off to tweak it in to 13.6 or 13.8 volts.  I came home a happy camper as I think I can now forget ordering the 30 amp unit ($680) and can probably run with landing lights in the pattern without showing a slight discharge.  I'll keep you posted.
