How To Test the Coil Circuits Without a Meter
You did it correctly teslamaniac. Providing you added an extra wire?
If you have NO meter, use a small bulb and battery to test continuity with the coils. Understand?
Use or make a simple Test Light
Use a battery that will light up a small bulb or LED. eg - Bicycle lamp, car test light or torch.
Connect a wire to one of the battery terminals [+ or -]
Then connect another wire to the other end of battery.
Connect these two wires to the bulb or LED and ensure it lights up clearly.
To test the coil circuits.
Mark all four wires from fan with tape and number them 1, 2, 3, and 4.
Simply remove one wire from bulb and connect it to wire No 1.
Connect wire No 2 to the bulb, where you just removed the wire above.
If the bulb lights up, you have found a complete circuit. [join with tape or make a note of both wire numbers].
If the bulb does NOT light up, test again with wire No 3.
If the bulb does NOT light up, test again with wire No 4.
You should now have found one pair of coil wires. These can be called the 'trigger' coil wires.
Repeat the bulb test with the two remaining wires and these should also light up. These will be your power coil wires.
If you cannot find two pairs of wires that complete the test circuit and light up the bulb, you will need to inspect the wiring to the fan and the soldered connections inside.
Check that the test bulb definately lights up when connected to battery and try the test again to be certain.
If you have a 12v battery, you can use one of these as a test light.
psss, I can't believe how long it takes to explain a simple technique
~~~
If you have two complete coil circuits remember this...
... if the motor does NOT work swap either T1 and T2 OR P1 and P2
~~~ DO NOT SWAP BOTH SETS! ~~~ read this post for more help
