and distributor.The coil is a BOSCH blue with 3.3 ohm primary.The coils resistance was tested.
Do i need a BOSCH voltage regulator.?Iam willing to go that route if it
is the solution.The BOSCH regulators are 10 times more expensive.
Also of note,the engine is running rough and i suspect it may be related.
Would greatly appreciate any help with this problem.
Best regards .

Ballast resistance would normally be located on the switched power (+12V) side of the coil. If located on the negative, distributor side of the coil, the observed voltage at the positive side of the coil will always be system voltage.
