ELECTRONIC IGNITION COMPONENTS TEST
For any ignition problems, always check the components as per the following procedure.
1. SPARK PLUG:
Check spark plug after cleaning in “Spark plug cleaning and testing Machine” replace if ……
•
SHORT
•
WORN OUT ELECTRODE
•
INSULATOR BROKEN
2. SUPPRESSOR CAP (SPARK PLUG CAP)
Check the resistance of suppressor cap by multimeter, if 5.0 K.ohms approx, otherwise replace it.
3.
COMBINATION SWITCH:
Check the continuity by multimeter.
4. H.T.COIL:
Mobike H.T. coil has separate ground terminal (Black)
•
Check primary coil resistance between green and yellow/black wire terminal, if less than 1.0 ohms,
otherwise replace H.T. coil.
•
Check secondary coil resistance between H.T. cable and earth wire it should be 7.5±1K.ohms,in
total includes 5.0 K.ohms series resistance of the suppressor cap, otherwise replace H.T. coil.
5. PICK UP COIL:
•
Check for its resistance value across blue-white and green-white wire it should be 150 to 300 ohms
at 20 otherwise replace pick up coil.
•
Remove spark plug & then connect a L.E.D. of 1.5 volts across blue-white and green-white wire,
kick the start lever to rotate magneto, L.E.D. should flash, otherwise replace the pick-up coil.
6. C.D.I. UNIT TEST:
•
Connect the defective C.D.I. in place of O.K. mobike C.D.I. where C.D.I. already working
satisfactory.If mobike starts easily, then unit is good, otherwise replace the C.D.I.unit.
•
Check for functioning of ignition timing auto advance by timing light, otherwise replace
C.D.I.unit (As shown in figure)
