Here are some shots of the nozzle alignment. I sighted down the nozzles as in the third pic, but looks like I could improve a bit with the drill bit.
Here is the damage to the runner. Some slight pitting on the inner surfaces of the buckets in addition to the dinged up edges.
Pitch diameter is 4 inch.
The alternator does use a rheostadt (12 ohm, I think) to control the field. Just the other night however, it apparently shorted out, and will now only supply field when turned all the way down.
Voltage reading at present is 13.2v at alt., 12.2v applied to batteries, and 11.5v on the field.
The hydro unit's ammeter does not work and has been bypassed. Amperage at the alternator has been taken with a multimeter. Meter is only rated for 10 amps--when I first used it I opened nozzles slowly to see when I would hit 10, but since it hit it just before reaching max flow, I decided to risk passing 10.
Amps read at the house are as shown on the system monitor.
The nozzles are not clogged, and the pressure gauge is new, has read consistent, and is consistant with surveyed head.
I think that addresses everyones q's.
