Windseeker 503 24v

denlow1

Here is where I am. Last February a micro burst storm snapped the 3" pipe tower that supported my 503 Southwest Windseeker. Luckily it landed in a pinon pine tree, preventing damage to the generator and blades. Long story short, I just yesterday got a new tilting tower base constructed and installed. I had a local auto electric shop install new bearings in the generator and up it went. Turbine was spinning well until I turned on the circuit breaker between generator and the 24 volt battery bank. The turbine immediately slowed to a crawl, just like twisting the positive and negative down leads together. Have checked proper positive / negative connections. Question 1: could the auto electric shop have crossed up polarity inside the generator?
Question 2: if the polarity was crossed, how much damage to the internal regulator likely occurred?
Anyone have any suggestions or potential electronic replacement parts?
Thanks

Can you verify the polarity at the base before closing breaker, while the blades are turning?

Does it use a modified PMA - Permanent Magnet Alternator?
Typically, the is no "regulator" inside, only the PM rotor, the Stator Coils, a 3-phase diode bridge and Pos / Neg power wires.
Did you check the PMA for full functionality before raising the pole?

I checked polarity at the base and it shows 22-29 v dc on the red wire.
I do not know if it uses a modified PMA. Just reading the owners manual it states: "Brushless neodymium permanent magnet alternator with a built in voltage regulator" it also states in the trouble shooting section "Do not connect it through another voltage regulator as it will confuse the Windseeker .....Do Not use a blocking diode in the wiring."
I have it connected on the battery side of my system (output side of Flex Max PV charge controllers.
Thanks for your response
