DIY Micro hydro generator - first run

I have recently been testing a micro version I built for low powered items such as LED lights and fans in our un-powered chicken coop. I've read that using a vehicle alternator isn't a great option as they're meant to spin at high RPM to get any useful wattage. A more efficient motor would be a direct drive BLDC (Brushless Direct Current) motor from a Samsung or LG washing machine. We have a stream on our property that flows during fall/winter/spring and dries up in summer. I don't have much elevation (around 10-15ft) change so it has fairly low head. I use 60ft of sewer drain 4inch PVC pipe and a gate valve to shut off the flow during maintenance. Our washing machine broke 2 out 3 spokes on its "star gear" that connects the stainless steel spinning drum to the motor and shook violently during spin cycle (very common problem). It was the perfect opportunity to repurpose it as a hydro generator. The wheel consists of two 20inch kids bike wheels, a 3/4" threaded rod shaft threaded into the BLDC splined shaft, 3inch PVC cut in halves as buckets, a pillow block, phase rectifier, capacitor to smooth out rectified sine wave ripples, and a 40 amp solar MPPT.
