kunan mo ng resistance tapos gamitan mo ng ohms law. gumamit ka ng ammeter para malaman mo yung kung tama specs yung makukuha mong value. or pwd rin kahit nakakabit sa otto mo yung fan, gamitan mo ng ammeter in a series connection tapos wait mo umandar yung fan. Dun pa lang makikita mo na kung sira yan o buo or kung may oscilloscope ka tingnan mo yung voltage spike nya para malaman mo kung sira na yung armature sa loob o manipis na ang carbon ng hindi mo na bubuksan ang motor. Pero pwd ka rin gumamit ng synchonomometer tapos lagyan mo ng tachometer para malaman mo kung tama pa yung rpm sa flow / gm / ms.

yan lang alam kong testing procedure dude aside from visual inspection.

is your fan belt driven? Try holding two blades of your fan (granting your car is off - please) turn left slowly and right slowly, if maganit na or hirap na i turn. Me problem ka. Usually the fan is connected via the water pump, cheap repair lang.

Apply 12V DC power to the power leads (preferably fused to OEM spec), taking note of the polarity. The fan should pull air from the front and blow it towards the engine with significant amount of volume. That should give you an instant go or no-go status of the fan.

The fan is defective if:

a. It does not turn or turns too slowly
b. Makes metallic noises (bearing or bushing problem)
c. Produces a lot of vibration (unbalanced or damaged blades)
d. The fuse blew (shorted)

salamat mga bro

.....check ko mamaya...

.....
may vibrations ka ba madadama just in case my trouble sa fan....?
pwede ka ba mamatayan ng makina just in case my trouble...?

Under normal operation, the fan vibration may be masked by the vibration produced by the engine. The better way is to operate them with the engine off so you can feel/hear/see anything that's unusual.

If the fan fails, it's only a matter of time before the engine overheats and seizes up. That's not good. It's a good idea to keep an eye on the gauges and idiot lamps every now and then so you can stop the car before anything turns for the worse.

Gawin mo ganito tanggalin mo connection ng fan at kumuha ka ng bagong wire at direkta mo sa Battery kung ayaw umandar sira na motor niyan. Linisin mo rin iyong connector sa fan baka may umido kaya loose connection.
