Re: Nicro Day-Night 2000 solar vent repair

Hi,

It's easy to fix a solarvent. You need to :
- Change the motor (you can buy for cheap in china)
- Balance the prop, or you'll break your motor again in few months

I've made a video to detail this : https://youtu.be/FREGvXFdu-Q

Gee Jason, that's a find. I'm going by Lowes later today and will definitely take a look. After going through all of my re-re-re-repairs having a few more inexpensive spares will be worth it. I'll report back if I find the same at our local store.

Ironically, when I went to the boat today, I pulled off the fan blade and sprayed some WD-40 on the shaft gave it a twist, and it began spinning. I put the fan blade back on and it was still running when I left two hours later, so maybe it's OK. Keeping my fingers crossed. Oh, and this is one of the ones that WM sold that had a totally enclosed battery compartment. If it does again, I may have to open the battery compartment with my Dremel tool .

Gary--

It might just be the battery. Before anything else, get a meter on the battery posts (without the battery of course) and see if your panel is still putting out amps. If so, and a recharge of the battery on your bench at home (or a new battery) doesn't revive the thing, Nicro sells a replacement motor for the new style vents and it's an easy swap.

FWIW...

So... At this point we're a few daze over six months since my re-repair of our 1980's era Solar Vent with a new $8.95 motor and the little beggar continues to spin away merrily blowing hot air out of the boat. I guess if I must spend $8.95 every 40 months or so to keep it going, that's not such a bad deal eh?

Next report next January or so!

Cheers!

Upon inquiry at an adjoining business I learned that the shop had closed some while ago because the owners "couldn't compete" with internet sellers. I have, of course, gone back to Sundance Solar and ordered two of the motors (one as a spare) for about what I paid for one at the local hobby shop although--with shipping charges--my cost ends up being just about the same save for the 6.5% sales tax not collected by the internet seller. Frankly, if his is "progress", I'll pass...

More later...
Well, my re-repaired Solar Vent has been sitting on my work bench since last evening, whirling away with one of the replacement motors from Sundance Solar like a dervish. This motor replacement went much more quickly than the original repair given my prior experience. The most problematical aspect (at least for me) was the process of soldering the tiny little wires from the solar panel to the tiny little posts on the motor, given my deteriorating vision (which also makes taking a round of sights a pain in the neck!). Never-the-less, the job is done. Based upon the longevity of the prior repair, I estimate the motors are good for about 29,200 hours of running time (40 months continuous) so I shouldn't have to repeat this exercise until late 2019, assuming I'm still around at that time myself.

One thing I have noticed is that the new motor does not respond quite as readily to power from the solar panel generated by reflected sunlight (vs. direct) as did the original. I suspect this is not a property of the motor itself but of some deterioration of the performance of the solar panel which the maker claims will have a service life of "...10 to 20 years". Given the environmental conditions the solar panel must endure--even under a clear cover--I suspect it may be loosing capacity rather more quickly than the maker's estimate. (To be one the safe side, I have ordered another of the solar panels while they are still available to keep with the extra drive motor in our spares kit)

N'any case, more reports to follow in due course....
