Hi Kevin.

I suggest the following steps:

1. Use a decent digital voltmeter to test the circuit as follows. If you don’t 
have one, head off to the store with at least $25.00 in your hot little hands 
and buy one. It will be very useful.
2. Make sure the panel breaker feeding the fan is turned on.
3. Using the meter, check for battery voltage between the output connection on 
the breaker feeding the fan and ground.
4. If there is no voltage on the output of the breaker, check the input side of 
the breaker to make sure it is getting power. You should now know if the 
breaker is good or not. Replace if needed or move the fan wire to another known 
good breaker.
5. Check the connections on the wire feeding your fan. Are they crimped 
properly? If in doubt, redo them.
6. If you have determined that electricity is present at the feed end of the 
fan wire and the fan is still not working, measure across the connections at 
the fan both with the fan switch turned on and off. There should be voltage 
present. If not, or if the voltage drops drastically when the fan switch is 
turned on, check your connections and the wire you installed carefully.
7. You should have found the problem by the end of step 6.

There may be some shaky connections in the fan itself that may have caused it 
to run at the battery and not when installed. Wiggle the wires….?

Hope this helps. 

Rich.

I wired it all up yesterday to my breaker panel and when trying to turn it on, 
nothing happened. I then took it off the wall and connected it directly to the 
battery, and it worked just fine. I then tried to connect to directly to the 
feed line of the breaker panel and it didn't work. 

I'm not an electrical expert but I would think connecting it the way I did to 
the breaker panel would not have a large voltage drop. I was using 16awg from 
the breaker to the mounting location. I might be a little low on the gauge of 
wire for that length I admit. That was my first guess. But connecting to the 
panel line feed directly still didn't do anything and that baffled me. 

Any ideas on what could be going wrong? The batteries are new last year. My 
battery meter was saying approx 70% charge capacity when doing all of this. The 
cabin lights and other electronics were working while I was trying to do this 
too. 

I'm at a complete loss here.
