I BOUGHT A HAVELLS ACCL WITH GENERATOR STOP FASCILITY(i.e- BASICALLY IT IS A AUTO CHANGE OVER SWITCH) FOR MY HONDA EXK 2000S HOME GENERATOR (WHICH START IN PETROL & RUN IN KEROSENE). ACCL HAS 8 POINT. 2 FOR MAINS(PH & NUE), 2 FOR LOAD, 2 FOR GEN AND 2 FOR IGNITION POINT(X1 & X2). THE IGNITION POINT IS SPECIALLY FOR AUTO ENGINE STOP WHEN MAINS POWER RESTORE. I CONNECT THIS X1 & X2 POINT TO THE GENERATOR STATER MOTOR & EARTHING POINT. BUT WHEN MAINS FAILS THE GENERATOR COULD NOT START, BUT WHEN DISCONNECT THOSE X1 OR X2 POINT, THEN THE GENERATOR START. BUT WHEN MAINS ON THEN THE GENERATOR SHOULD START, AND WHEN I OFF THE MAINS THE GENERATOR AUTOMATICALLY STOP. PLESE HELP ME HOW I STOP THE GENERATOR AUTOMATICALLY WHEN THE MAINS RESTORE.
