I concur with Ductape ! Much too high ! Something is the chassis wiring could be "tricking" the alternator, but it need to fixed soon. You have already "hurt" your batteries. Don't expect them to live a long life.
Researching this overcharging issue online I came accross some sentiments similar to your's regarding something in the wiring possibly being an issue. One thing I saw mentioned a couple of different places was checking all of the ground connections. I'm going to do that tomorrow. Make sure all I can find are tight.
The house batteries are definitely "hurt." Especially the one of them which leaked much more than the other. I'm going to replace both. Not going to limp them along.
Cleaned up the batteries with baking soda/water last summer.
After looking back at some old notes on voltages, it would not suprise me to find out that this alternator has been perpetually putting out 15+ volts the whole time we've had it.
I'm also going to put my stand-alone charger (ctek unit) on both the starting and second chassis battery to ensure they are both fully charged to potentially rule that out as a reason the alternator may be "stuck" in 15+ volt mode.
