Four Winds II Wind Generator

I have a Four Winds II Wind Generator which has a defective motor which I have not been able to replace. Everything else seems to be OK the last time I used it. I would like to sell it. $350(I am on Marco Island, Fl)
Check it out on Four Winds Wind Generator II | Passport 40 S/V Grendel

Re: Four Winds II Wind Generator

How would you define defective?
If my memory serves me right, o test you should get 7-10V when spinning shaft by hand when blades are off. Was shaft not spinning?

Re: Four Winds II Wind Generator

There are a number of problems with the motor. First a couple of magnets detached themselves from the case interfering with the shaft rotating. Secondly the commutator is very worn and one or more of the armature
winding are open.

Re: Four Winds II Wind Generator

The magnets coming loose is a common problem with these units and they can be epoxied back in place. There is pretty much nothing in these units that can't be fixed by a good generator/alternator shop. The expense will determine how bad things are and how that compares to replacing a unit. Even if you find a used unit, these same issue will present themselves later. We used a Four Winds for over 15 years in constant use. Chuck

Re: Four Winds II Wind Generator

Do you know what causes them to come loose? So far so good for me. 5+ years trouble free on the generator.

Re: Four Winds II Wind Generator

The epoxy that held the magnets was not of good quality and failed on many units. They changed that and the problem went away. Chuck

My four winds II, old style w/brushes, is in the shop but they don,t know what to do about those capacitors or whatever they are inside the generator. Do you/anyone know what those components are or if they are even necessary?

Re: Four Winds II Wind Generator

They may be electrical noise suppression capacitors. I doubt if they are bad. It will probably work ok without them.

I'm not sure what you mean by capacitors. Are you referring to the magnets?

Re: Four Winds II Wind Generator

Magnets(4) are epoxied to the case of the motor housing(you hope). I know he use to install noise suppression capacitors somewhere. I thought maybe that was what you were referring to. The noise suppression was used in an attempt to eliminate radiated rf signals from the brushes interfering ham or ssb receivers.

Re: Four Winds II Wind Generator

I was confused because the noise suppression capacitors were mounted inside the generator. In my manual, they were shown in the 2" mounting pole. I am having the shop remove them ( they are broken) and if needed I will put new ones out side the generator. I don't have an SSB or Ham.
