BY USING TEST LAMP ,WE CAN EASYLY IDENTIFY THE MOTOR LEAED.
1. APPLY PHASE TO THE ANY ONE LEAD OF THE MOTOR & CHECK THE
TEST LAMP TO OTHER LEAD, WHICH LEAD - BULB IF GLOW THAT IS
THE OTHER END OF THAT LEAD. IT MEANS SUPPOSE I ASSUME ONE
LEAD IS U1 & THAT IS CONNECT TO THE PHASE & CHECK THE TEST
LEMP TO THE ANOTHER LEAD WHEN BULB WILL GLOW THATS LEAD IS
U2.
