Today I spent some time trying different nozzles just to see if I could wrangle out those last few RPMs needed to get past 12 volts .. I bored two out to 3/8ths and dremmeled the crap out of them, finishing the interior with some fine gauge steel wool wrapped around a dremel shaft and polished it till the battery died on the tool. I made sure it was a smooth angle to the tip and got rid of all the scratch marks from the drill bit. Put them in and just ran the hydro with a multi-meter and was getting around 7 volts with a single jet. Pretty sweet .. the most I ever got before was around 5.5. With both jets on and with some fiddling with the angles I hit 13!! So I turned connected them to the batteries and whadya know.. its charging. The battery bank is at 12.4 and when I hit the switch to complete the circuit the alternator comes under load and keeps on spinning!!! So thats that then. Now just have to keep tweaking things to gain more performance. I might bore some out a bit bigger and see how that goes. The nozzles i'm using don't have much room left .. any larger bores and i'm risking going through a side wall, but they're only like 2 bucks each so its not a huge deal if I screw one up. speaking of which think i'll have to get to town and buy a few more to play with. Hey I can't thank all of you enough for the advice and telling me i'm doing something bone headed once in a while -- its been a huge help. -zachary
