AH OKY THANK YOU FERMIN COLLEGE AND THERE IS NO WAY TO TAKE A FAN OUT AND TEST IT HOW WOULD YOU DO?
Johan
Yes, take it outside and try it with a square battery, 9vdc or a 9vdc source, the 2 Red and yellow cables are positive and the negative white and blue, that does not connect, since it is for the speed variator, greetings
Thank you!! Fermin 007 was the cooler fan, you were equally right thanks to colleague Lusangor for his opinions !! a thousand blessings!
