I finally got around to rebuild my solar vent.  It seems to work fine and 
all was done for under 30 bucks. 

I put the new motor on (The old one was toast both brushes and commutator 
were completely shot.) and replaced the battery with an Eneloop  C Size 
3000 mah I found on Amazon (It is somehow much more expensive now) 

To make it happen: I had to Dremel the casing a bit as the motor shaft was 
slightly short, I added a couple of small zip ties to tighten the fan's 
grip on the shaft, I made a little plastic motor holder arm, and wrapped 
the motor with a couple turns of double sided tape to help hold the it 
tight. 

Here are the pictures:

Hi Nate, 

Sounds to me like one of the commutators in the motor is no longer getting 
current and that creates a dead spot.  I.E your motor is toast. 

You can try connecting a good AA battery directly to the motor if you want 
to test and know for  sure

Here's a good replacement if you or one of your friends is handy with a 
soldering iron:

You also need to shim it some for a perfect fit.  I found out about it on 
one of the cruisers forums, the guy reported excellent results.  It's a 
lot cheaper than a new vent.  I just received mine along with a special 
Eneloop battery I found on Amazon.  I'll report back when I install.

Subject: Stus-List solar vent wiggles, doesn't rotate

My Nicro 4" solar vent, maybe 4 years old, would not run this season.
I replaced the NI-MH C cell, left it switched off for a couple days to
charge in the sun, and turned it on - it wiggles back and forth a little,
but doesn't rotate - same as the with the old battery.

Ideas? solutions?

Thanks

Nate
