Sonata V6-3.0L (1991)
Coil L1 And L2 Test Hook-up
Apply positive power to terminal 7 with negative power applied to terminal 10.
Check terminals 3 and 4: should be conductive (0 ohm).
Remove power.
To test coil L3:
Check terminals 1 and 6, should be non-conductive (infinite ohm).
Check terminals 8(+) and 6(-), should be non-conductive (infinite ohm).
Check terminals 8(-) and 6(+), should be conductive (0 ohm).
Coil L3 Test Hook-up
Apply positive power to terminal 6 with negative power applied to terminal 8.
Check terminals 1 and 6, should be conductive (0 ohm)
Remove power.
Test between each terminal and the case: All terminals should be non-conductive (infinite ohm).
