Yeah I might swap that out, but those were handy and had the fittings. I
could probably just move to that clear poly but I don't have the fittings
for doing that on hand.
I need to do some other stuff first.

Right around 12 volts .. I think my multi-meter is messed up because It
won't read amps at the moment, its always zero. But I hooked a dead car
battery up and it from round 4 volts to 7.5 after 10 mins of running or
so. I don't want to run it longer until I pipe in a place for the excess
water to go .. back down the hill into the stream. Its been fine for
testing but when you run it for a while that water needs a place to go!
Once again that was a detail I didn't want to bother with till I thought
the generator part would actually work.
